We pledge to act and interact in ways that contribute to an open, welcoming, diverse, inclusive, and healthy community. ## Our Standards Examples of behavior that contributes to a positive environment for our community includes: * Demonstrating empathy and kindness toward other people * Being respectful of differing opinions, viewpoints, and experiences * Giving and gracefully accepting constructive feedback * Accepting responsibility and apologizing to those affected by our mistakes, and learning from the experience * Focusing on what is best not just for us as individuals, but for the overall community Examples of unacceptable behavior include: * The use of sexualized language or imagery, and sexual attention or advances of any kind * Trolling, insulting or derogatory comments, and personal or political attacks * Public or private harassment * Publishing others' private information, such as a physical or email address, without their explicit permission * Other conduct that could reasonably be considered inappropriate in a professional setting ## Enforcement Responsibilities Community leaders are responsible for clarifying and enforcing our standards of acceptable behavior and will take appropriate and fair corrective action in response to any behavior that they deem inappropriate, threatening, offensive, or harmful. Community leaders have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, and will communicate reasons for moderation decisions when appropriate. ## Scope This Code of Conduct applies within all community spaces and also applies when an individual is officially representing the community in public spaces. Examples of representing our community include using an official e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. ## Enforcement Instances of abusive, harassing, or otherwise unacceptable behavior may be reported to the community leaders responsible for enforcement at [cfug-team@googlegroups.com](mailto:cfug-team@googlegroups.com). All complaints will be reviewed and investigated promptly and fairly. All community leaders are obligated to respect the privacy and security of the reporter of any incident. ## Enforcement Guidelines Community leaders will follow these Community Impact Guidelines in determining the consequences for any action they deem in violation of this Code of Conduct: ### 1. Correction **Community Impact**: Use of inappropriate language or other behavior deemed unprofessional or unwelcome in the community. **Consequence**: A private, written warning from community leaders, providing clarity around the nature of the violation and an explanation of why the behavior was inappropriate. A public apology may be requested. ### 2. Warning **Community Impact**: A violation through a single incident or series of actions. **Consequence**: A warning with consequences for continued behavior. No interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, for a specified period of time. This includes avoiding interactions in community spaces as well as external channels like social media. Violating these terms may lead to a temporary or permanent ban. ### 3. Temporary Ban **Community Impact**: A serious violation of community standards, including sustained inappropriate behavior. **Consequence**: A temporary ban from any sort of interaction or public communication with the community for a specified period of time. No public or private interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, is allowed during this period. Violating these terms may lead to a permanent ban. ### 4. Permanent Ban **Community Impact**: Demonstrating a pattern of violation of community standards, including sustained inappropriate behavior, harassment of an individual, or aggression toward or disparagement of classes of individuals. **Consequence**: A permanent ban from any sort of public interaction within the community. ## Attribution This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 2.0, available at https://www.contributor-covenant.org/version/2/0/code_of_conduct.html. Community Impact Guidelines were inspired by [Mozilla's code of conduct enforcement ladder](https://github.com/mozilla/diversity).

The support range is limited due to the above condition. Therefore, we have a general compatibility policy to help people that are not actively adapting SDK updates or intended to use any old SDKs to acknowledge the support range. ## Policy Details For all packages, the oldest Dart SDK we typically support is one that was **released less than 2 years ago**. ### Exceptions - The minimum SDK version will follow the dependencies' requirement. For example: `http2: ^2.1.0` requires Dart SDK >=3.0.0. - The implementation can no longer compatible between the latest and previous SDKs. - Previous SDKs have security issues that require to use a new version. To raise your suggestions and reports, use the issue tracker or contact cfug-team@googlegroups.com if you want to do this privately. ================================================ FILE: CONTRIBUTING-ZH.md ================================================ # 贡献指南 Language: [English](CONTRIBUTING.md) | 简体中文 首先，感谢您考虑为 `dio` 项目做出贡献！像这样的开源项目得以成长和繁荣，多亏了像您这样的贡献者。无论您是在修复错误、添加新功能、改进文档还是报告问题，每一份贡献都是宝贵和值得赞赏的。 本文档提供了一些指南，以帮助确保您的贡献尽可能有效。在提交您的贡献之前，请花一点时间阅读这些指南。 请记住，每个为这个项目做出贡献的人都需要遵循我们的行为准则。这有助于确保所有贡献者的积极和包容环境。 再次感谢您的贡献，我们期待看到您将为 `dio` 项目带来什么！ ## 创建好的工单 > [!TIP] > 在创建新问题之前，搜索已有的工单和拉取请求以避免重复是一个好习惯。 ### 错误报告 报告错误时，请包括以下信息： 1. **标题**：简短描述性的错误标题。 2. **包**：指定有问题的包。 3. **版本**：您正在使用的包版本。 4. **操作系统**：出现问题的操作系统。 5. **适配器**：指定使用的适配器。 6. **`flutter doctor -v` 的输出**：使用 Flutter 时需要。 7. **Dart 版本**：您使用的 Dart 版本。 8. **重现步骤**：详细步骤说明如何重现错误。 9. **预期结果**：您期望发生的事情。 10. **实际结果**：实际发生的事情。包括日志、屏幕截图或任何其他相关信息。 ### 功能请求 请求新功能时，请包括以下信息： 1. **标题**：功能请求的简短描述性标题。 2. **请求声明**：描述您认为 `dio` 项目能解决但目前没有解决的问题。 3. **解决方案头脑风暴**：分享您的想法，关于如何解决问题。如果您没有特定的解决方案，那也没关系！ > [!TIP] > 记住，您提供的信息越多，我们就越容易理解和解决问题。感谢您的贡献！ > 请避免评论旧的、已关闭的工单。如果旧问题似乎与您的问题有关但并未完全解决您的问题，最好开一个新工单并引用旧的。 ## 开发 此项目使用 [Melos](https://github.com/invertase/melos) 管理单体仓库和大多数任务。Melos 是一个为 Dart 和 Flutter 的多包项目优化工作流的工具。有关如何使用 Melos 的更多信息，请参阅 [Melos 文档](https://melos.invertase.dev)。 ### 设置 开始之前，您需要全局安装 Melos： ```bash dart pub global activate melos ``` 在安装 Melos 后，可以克隆仓库并安装依赖项： ```bash git clone https://github.com/cfug/dio.git cd dio melos bootstrap ``` ## 提交更改 在以拉取请求提交您的更改之前，请确保格式化和分析您的代码并运行所有测试。以下是您应该了解的主要 melos 脚本： ### 代码质量 要格式化（和修复）所有包，请运行： ```bash melos run format # 或者 melos run format:fix ``` 要分析所有包，请运行： ```bash melos run analyze ``` ### 测试 要运行所有测试，请使用： ```bash melos run test ``` 可以使用适当的脚本运行单个测试目标： ```bash melos run test:vm melos run test:web melos run test:web:chrome melos run test:web:firefox ``` ================================================ FILE: CONTRIBUTING.md ================================================ # Contributing Guidelines Language: English | [简体中文](CONTRIBUTING-ZH.md) First of all, thank you for considering contributing to the `dio` project!

Improve performance when sending binary data (`List`/`Uint8List`). ## 5.1.2 - Allow `FormData` to send a null entry value as an empty string. ## 5.1.1 - Revert changes to `CancelToken.cancel()` behavior, as a result the `DioError` provided by the `CancelToken.cancelError` does not contain useful information when the token was not used with a request. - Fix wrong `ListFormat` being used for comparison during encoding of `FormData` and `application/x-www-form-urlencoded`, resulting in potential wrong output encoding for `ListFormat.multi` and `ListFormat.multiCompatible` since Dio 4.0.x. - Respect `Options.listFormat` when encoding `x-www-url-encoded` content. ## 5.1.0 - Fix double-completion when using `connectionTimeout` on web platform. - Allow defining adapter methods through their constructors. - Fix `FormData` encoding regression for maps with dynamic keys, introduced in 5.0.3. - Mark several static `DioMixin` functions as `@internal`. - Make `DioError.stackTrace` non-nullable. - Ensure `DioError.stackTrace` always points to the correct call site. ## 5.0.3 - Imply `List` as JSON content in `ImplyContentTypeInterceptor`. - Fix `FormData` encoding for collections and objects. ## 5.0.2 - Improve code formats according to linter rules. - Remove the force conversion for the response body. - Fix `DioErrorType.cancel` in `Interceptors`. - Fix wrong encoding of collection query parameters. - Fix "unsupported operation" error on web platform. ## 5.0.1 - Add `ImplyContentTypeInterceptor` as a default interceptor. - Add `Headers.multipartFormDataContentType` for headers usage. - Fix variable shadowing of `withCredentials` in `browser_adapter.dart`. ## 5.0.0 - Raise the min Dart SDK version to 2.15.0 to support `BackgroundTransformer`. - Change `Dio.transformer` from `DefaultTransformer` to `BackgroundTransformer`. - Remove plain ASCII check in `FormData`. - Allow asynchronous method with `savePath`. - Allow `data` in all request methods. - A platform independent `HttpClientAdapter` can now be instantiated by doing `dio.httpClientAdapter = HttpClientAdapter();`. - Add `ValidateCertificate` to handle certificate pinning better. - Support `Content-Disposition` header case sensitivity. ### Breaking Changes - The default charset `utf-8` in `Headers` content type constants has been removed. - `BaseOptions.setRequestContentTypeWhenNoPayload` has been removed. - Improve `DioError`s. There are now more cases in which the inner original stacktrace is supplied. - `HttpClientAdapter` must now be implemented instead of extended. - Any classes specific to `dart:io` platforms can now be imported via `import 'package:dio/io.dart';`. Classes specific to web can be imported via `import 'package:dio/browser.dart';`. - `connectTimeout`, `sendTimeout`, and `receiveTimeout` are now `Duration`s. ## 4.0.6 - fix #1452 ## 4.0.5 - require Dart `2.12.1` which fixes exception handling for secure socket connections (#45214) - Only delete file if it exists when downloading. - Fix `BrowserHttpClientAdapter` canceled hangs - Correct JSON MIME Type detection - [Web] support send/receive progress in web platform - refactor timeout logic - use 'arraybuffer' instead of 'blob' for xhr requests in web platform ## 4.0.4 - Fix fetching null data in a response ## 4.0.3 - fix #1311 ## 4.0.2 - Add QueuedInterceptor - merge #1316 #1317 ## 4.0.1 - merge pr #1177 #1196 #1205 #1224 #1225 #1227 #1256 #1263 #1291 - fix #1257 ## 4.0.0 stable version ## 4.0.0-prev3 - fix #1091 , #1089 , #1087 ## 4.0.0-prev2 - fix #1082 and # 1076 ## 4.0.0-prev1 **Interceptors:** Add `handler` for Interceptor APIs which can specify the subsequent interceptors processing logic more finely (whether to skip them or not). ## 4.0.0-beta7 - fix #1074 ## 4.0.0-beta6 - fix #1070 ## 4.0.0-beta5 - support ListParam ## 4.0.0-beta4 - fix #1060 ## 4.0.0-beta3 - rename CollectionFormat to ListFormat - change default value of Options.listFormat from `multiCompatible` to `multi` - add upload_stream_test.dart ## 4.0.0-beta2 - support null-safety - add `CollectionFormat` configuration in Options - add `fetch` API for Dio - rename DioErrorType enums from uppercase to camel style - rename 'Options.merge' to 'Options.copyWith' ## 3.0.10 2020.8.7 1. fix #877 'dio.interceptors.errorLock.lock()' 2. fix #851 3. fix #641 ## 3.0.9 2020.2.24 - Add test cases ## 3.0.8 2019.12.29 - Code style improvement ## 3.0.7 2019.11.25 - Merge #574 : fix upload image header error, support both oss and other server ## 3.0.6 2019.11.22 - revert #562, and fixed #566 ## 3.0.5 2019.11.19 - merge #557 #531 ## 3.0.4 2019.10.29 - fix #502 #515 #523 ## 3.0.3 2019.10.1 - fix encode bug ## 3.0.2 2019.9.26 - fix #474 #480 ## 3.0.2-dev.1 2019.9.20 - fix #470 #471 ## 3.0.1 2019.9.20 - Fix #467 - Export `DioForNative` and `DioForBrowser` classes. ## 3.0.0 ### New features - Support Flutter Web. - Extract [CookieManager](../plugins/cookie_manager) into a separate package（No need for Flutter Web）. - Provides [HTTP/2.0 HttpClientAdapter](../plugins/http2_adapter). ### Change List - ~~Options.cookies~~ - ~~Options.connectionTimeout~~ ；We should config connection timed out in `BaseOptions`. For keep-alive reasons, not every request requires a separate connection。 - `Options.followRedirects`、`Options.maxRedirects`、`Response.redirects` don't make sense in Flutter Web，because redirection can be automatically handled by browsers. - ~~FormData.from~~，use `FormData.fromMap` instead. - Delete ~~Formdata.asBytes()~~、~~Formdata.asBytesAsync()~~ , use `Formdata.readAsBytes()` instead. - Delete ~~`UploadFileInfo`~~ class， `MultipartFile` instead. - The return type of Interceptor's callback changes from `FutureOr` to `Future`. The reason is [here](https://dart.dev/guides/language/effective-dart/design#avoid-using-futureort-as-a-return-type). - The type of `Response.headers` changes from `HttpHeaders` to `Headers`, because `HttpHeaders` is in "dart:io" library which is not supported in Flutter Web. ## 2.1.16 Add `deleteOnError` parameter to `downloadUri` ## 2.1.14 - fix #402 #385 #422 ## 2.1.13 - fix #369 ## 2.1.12 - fix #367 #365 ## 2.1.10 - fix #360 ## 2.1.9 - support flutter version>=1.8 (fix #357) ## 2.1.8 - fix #354 #312 - Allow "delete" method with request body(#223) ## 2.1.7 - fix #321 #318 ## 2.1.6 - fix #316 ## 2.1.5 - fix #309 ## 2.1.4 - Add `options.responseDecoder` - Make DioError catchable by implementing Exception instead of Error ## 2.1.3 Add `statusMessage` attribute for `Response` and `ResponseBody` ## 2.1.2 First Stable version for 2.x ## 2.0 **Refactor the Interceptors** - Support add Multiple Interceptors. - Add Log Interceptor - Add CookieManager Interceptor **API** - Support Uri - Support `queryParameters` for all request API - Modify the `get` API **Options** - Separate Options to three class: Options、BaseOptions、RequestOptions - Add `queryParameters` and `cookies` for BaseOptions **Adapter** - Abstract HttpClientAdapter layer. - Provide a DefaultHttpClientAdapter which make http requests by `dart:io:HttpClient` ## 0.1.8 - change file name "TransFormer" to "Transformer" - change "dio.transFormer" to "dio.transformer" - change deprecated "UTF8" to "utf8" ## 0.1.5 - add `clear` method for dio instance ## 0.1.4 - fix `download` bugs ## 0.1.3 - support upload files with Array - support create `HttpClient` by user self in `onHttpClientCreate` - support generic - bug fix ## 0.0.1 - Initial version, created by Stagehand [Migration Guide]: doc/migration_guide.md ================================================ FILE: dio/LICENSE ================================================ MIT License Copyright (c) 2018 Wen Du (wendux) Copyright (c) 2022 The CFUG Team Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

final dio = Dio(); void request() async { Response response; response = await dio.get('/test?id=12&name=dio'); print(response.data.toString()); // The below request is the same as above. response = await dio.get( '/test', queryParameters: {'id': 12, 'name': 'dio'}, ); print(response.data.toString()); } ``` ### 发起一个 `POST` 请求: ```dart response = await dio.post('/test', data: {'id': 12, 'name': 'dio'}); ``` ### 发起多个并发请求 ```dart List responses = await Future.wait([dio.post('/info'), dio.get('/token')]); ``` ### 下载文件 ```dart response = await dio.download( 'https://www.google.com/', '${(await getTemporaryDirectory()).path}google.html', ); ``` ### 以流的方式接收响应数据 ```dart final rs = await dio.get( url, options: Options(responseType: ResponseType.stream), // 设置接收类型为 `stream` ); print(rs.data.stream); // 响应流 ``` ### 以二进制数组的方式接收响应数据 ```dart final rs = await dio.get( url, options: Options(responseType: ResponseType.bytes), // 设置接收类型为 `bytes` ); print(rs.data); // 类型: List ``` ### 发送 `FormData` ```dart final formData = FormData.fromMap({ 'name': 'dio', 'date': DateTime.now().toIso8601String(), }); final response = await dio.post('/info', data: formData); ``` ### 通过 `FormData` 上传多个文件 ```dart final formData = FormData.fromMap({ 'name': 'dio', 'date': DateTime.now().toIso8601String(), 'file': await MultipartFile.fromFile('./text.txt', filename: 'upload.txt'), 'files': [ await MultipartFile.fromFile('./text1.txt', filename: 'text1.txt'), await MultipartFile.fromFile('./text2.txt', filename: 'text2.txt'), ] }); final response = await dio.post('/info', data: formData); ``` ### 监听发送（上传）数据进度 ```dart final response = await dio.post( 'https://www.dtworkroom.com/doris/1/2.0.0/test', data: {'aa': 'bb' * 22}, onSendProgress: (int sent, int total) { print('$sent $total'); }, ); ``` ### 以流的形式提交二进制数据 ```dart // Binary data final postData = [0, 1, 2]; await dio.post( url, data: Stream.fromIterable(postData.map((e) => [e])), // 构建 Stream> options: Options( headers: { Headers.contentLengthHeader: postData.length, // 设置 content-length. }, ), ); ``` 注意：如果要监听提交进度，则必须设置content-length，否则是可选的。 你可以在这里查看 [全部示例](example)。 ## Dio APIs ### 创建一个Dio实例，并配置它 > 建议在项目中使用Dio单例，这样便可对同一个dio实例发起的所有请求进行一些统一的配置， > 比如设置公共header、请求基地址、超时时间等。 > 这里有一个在[Flutter工程中使用Dio单例](../example_flutter_app) > （定义为top level变量）的示例供开发者参考。 你可以使用默认配置或传递一个可选 `BaseOptions`参数来创建一个Dio实例 : ```dart final dio = Dio(); // With default `Options`. void configureDio() { // Update default configs. dio.options.baseUrl = 'https://api.pub.dev'; dio.options.connectTimeout = Duration(seconds: 5); dio.options.receiveTimeout = Duration(seconds: 3); // Or create `Dio` with a `BaseOptions` instance. final options = BaseOptions( baseUrl: 'https://api.pub.dev', connectTimeout: Duration(seconds: 5), receiveTimeout: Duration(seconds: 3), ); final anotherDio = Dio(options); // Or clone the existing `Dio` instance with all fields. final clonedDio = dio.clone(); } ``` Dio 的核心 API 是： ```dart Future> request( String path, { Object? data, Map? queryParameters, CancelToken? cancelToken, Options? options, ProgressCallback? onSendProgress, ProgressCallback? onReceiveProgress, }); ``` ```dart final response = await dio.request( '/test', data: {'id': 12, 'name': 'dio'}, options: Options(method: 'GET'), ); ``` ### 请求配置 在 Dio 中有两种配置概念：`BaseOptions` 和 `Options`。 `BaseOptions` 描述的是 Dio 实例的一套基本配置，而 `Options` 描述了单独请求的配置信息。 以上的配置会在发起请求时进行合并。 下面是 `Options` 的配置项： ```dart /// HTTP 请求方法。 String method; /// 发送数据的超时设置。 /// /// 超时时会抛出类型为 [DioExceptionType.sendTimeout] 的 /// [DioException]。 /// /// `null` 或 `Duration.zero` 即不设置超时。 Duration? sendTimeout; /// 接收数据的超时设置。 /// /// 这里的超时对应的时间是： /// - 在建立连接和第一次收到响应数据事件之前的超时。 /// - 每个数据事件传输的间隔时间，而不是接收的总持续时间。 /// /// 超时时会抛出类型为 [DioExceptionType.receiveTimeout] 的 /// [DioException]。 /// /// `null` 或 `Duration.zero` 即不设置超时。 Duration? receiveTimeout; /// 可以在 [Interceptor]、[Transformer] 和 /// [Response.requestOptions] 中获取到的自定义对象。 Map? extra; /// HTTP 请求头。 /// /// 请求头的键是否相等的判断大小写不敏感的。 /// 例如：`content-type` 和 `Content-Type` 会视为同样的请求头键。 Map? headers; /// 是否保留请求头的大小写。 /// /// 默认值为 false。 /// /// 该选项在以下场景无效： /// - XHR 不支持直接处理。 /// - 按照 HTTP/2 的标准，只支持小写请求头键。 bool? preserveHeaderCase; /// 表示 [Dio] 处理请求响应数据的类型。 /// /// 默认值为 [ResponseType.json]。 /// [Dio] 会在请求响应的 content-type /// 为 [Headers.jsonContentType] 时自动将响应字符串处理为 JSON 对象。 /// /// 在以下情况时，分别使用： /// - `plain` 将数据处理为 `String`； /// - `bytes` 将数据处理为完整的 bytes。 /// - `stream` 将数据处理为流式返回的二进制数据； ResponseType? responseType; /// 请求的 content-type。 /// /// 请求默认的 `content-type` 会由 [ImplyContentTypeInterceptor] /// 根据发送数据的类型推断。它可以通过 /// [Interceptors.removeImplyContentTypeInterceptor] 移除。 String? contentType; /// 判断当前返回的状态码是否可以视为请求成功。 ValidateStatus? validateStatus; /// 是否在请求失败时仍然获取返回数据内容。 /// /// 默认为 true。 bool? receiveDataWhenStatusError; /// 参考 [HttpClientRequest.followRedirects]。 /// /// 默认为 true。 bool? followRedirects; /// 当 [followRedirects] 为 true 时，指定的最大重定向次数。 /// 如果请求超出了重定向次数上线，会抛出 [RedirectException]。 /// /// 默认为 5。 int? maxRedirects; /// 参考 [HttpClientRequest.persistentConnection]。 /// /// 默认为 true。 bool? persistentConnection; /// 对请求内容进行自定义编码转换。 /// /// 默认为 [Utf8Encoder]。 RequestEncoder? requestEncoder; /// 对请求响应内容进行自定义解码转换。 /// /// 默认为 [Utf8Decoder]。 ResponseDecoder? responseDecoder; /// 当请求参数以 `x-www-url-encoded` 方式发送时，如何处理集合参数。 /// /// 默认为 [ListFormat.multi]。 ListFormat? listFormat; ``` 此处为 [完整的代码示例](../example_dart/lib/options.dart)。 ### 响应数据 当请求成功时会返回一个Response对象，它包含如下字段： ```dart /// 响应数据。可能已经被转换了类型, 详情请参考 [ResponseType]。 T? data; /// 响应对应的请求配置。 RequestOptions requestOptions; /// 响应的 HTTP 状态码。 int? statusCode; /// 响应对应状态码的详情信息。 String? statusMessage; /// 响应是否被重定向 bool isRedirect; /// 请求连接经过的重定向列表。如果请求未经过重定向，则列表为空。 List redirects; /// 在 [RequestOptions] 中构造的自定义字段。 Map extra; /// 响应对应的头数据。 Headers headers; ``` 请求成功后，你可以访问到下列字段： ```dart final response = await dio.get('https://pub.dev'); print(response.data); print(response.headers); print(response.requestOptions); print(response.statusCode); ``` 注意，`Response.extra` 与 `RequestOptions.extra` 是不同的实例，互相之间无关。 ### 拦截器 每个 Dio 实例都可以添加任意多个拦截器，他们会组成一个队列，拦截器队列的执行顺序是先进先出。 通过使用拦截器，你可以在请求之前、响应之后和发生异常时（未被 `then` 或 `catchError` 处理） 做一些统一的预处理操作。 ```dart dio.interceptors.add( InterceptorsWrapper( onRequest: (RequestOptions options, RequestInterceptorHandler handler) { // 如果你想完成请求并返回一些自定义数据，你可以使用 `handler.resolve(response)`。 // 如果你想终止请求并触发一个错误，你可以使用 `handler.reject(error)`。 return handler.next(options); }, onResponse: (Response response, ResponseInterceptorHandler handler) { // 如果你想终止请求并触发一个错误，你可以使用 `handler.reject(error)`。 return handler.next(response); }, onError: (DioException error, ErrorInterceptorHandler handler) { // 如果你想完成请求并返回一些自定义数据，你可以使用 `handler.resolve(response)`。 return handler.next(error); }, ), ); ``` 一个简单的自定义拦截器示例: ```dart import 'package:dio/dio.dart'; class CustomInterceptors extends Interceptor { @override void onRequest(RequestOptions options, RequestInterceptorHandler handler) { print('REQUEST[${options.method}] => PATH: ${options.path}'); super.onRequest(options, handler); } @override void onResponse(Response response, ResponseInterceptorHandler handler) { print('RESPONSE[${response.statusCode}] => PATH: ${response.requestOptions.path}'); super.onResponse(response, handler); } @override Future onError(DioException err, ErrorInterceptorHandler handler) async { print('ERROR[${err.response?.statusCode}] => PATH: ${err.requestOptions.path}'); super.onError(err, handler); } } ``` #### 完成和终止请求/响应 在所有拦截器中，你都可以改变请求执行流， 如果你想完成请求/响应并返回自定义数据，你可以 resolve 一个 `Response` 对象 或返回 `handler.resolve(data)` 的结果。 如果你想终止（触发一个错误，上层 `catchError` 会被调用）一个请求/响应， 那么可以 reject 一个`DioException` 对象或返回 `handler.reject(errMsg)` 的结果。 ```dart dio.interceptors.add( InterceptorsWrapper( onRequest: (options, handler) { return handler.resolve( Response(requestOptions: options, data: 'fake data'), ); }, ), ); final response = await dio.get('/test'); print(response.data); // 'fake data' ``` #### QueuedInterceptor 如果同时发起多个网络请求，则它们是可以同时进入`Interceptor` 的（并行的）， 而 `QueuedInterceptor` 提供了一种串行机制： 它可以保证请求进入拦截器时是串行的（前面的执行完后后面的才会进入拦截器）。 ##### 例子 假设这么一个场景：出于安全原因，我们需要给所有的请求头中添加一个 `csrfToken`， 如果 `csrfToken` 不存在，我们先去请求 `csrfToken`，获取到 `csrfToken` 后再重试。 假设刚开始的时候 `csrfToken` 为 null，如果允许请求并发，则这些并发请求并行进入拦截器时 `csrfToken` 都为 null，所以它们都需要去请求 `csrfToken`，这会导致 `csrfToken` 被请求多次。 为了避免不必要的重复请求，可以使用 `QueuedInterceptor`， 这样只需要第一个请求处理一次即可。 完整的示例代码请点击 [这里](../example_dart/lib/queued_interceptor_crsftoken.dart). #### 日志拦截器 我们可以添加 `LogInterceptor` 拦截器来自动打印请求和响应等日志： **注意：** `LogInterceptor` 应该保持最后一个被添加到拦截器中， 否则在它之后进行处理的拦截器修改的内容将无法体现。 #### Dart ```dart dio.interceptors.add(LogInterceptor(responseBody: false)); // 不输出响应内容体 ``` **注意：** 默认的 `logPrint` 只会在 DEBUG 模式（启用了断言） 的情况下输出日志。 你也可以使用 `dart:developer` 中的 `log` 来输出日志（在 Flutter 中也可以使用）。 #### Flutter 在 Flutter 中你应该使用 `debugPrint` 来打印日志。 这样也会让调试日志能够通过 `flutter logs` 获取到。 **注意：** `debugPrint` 的意义 **不是只在 DEBUG 模式下打印**， 而是对输出内容进行节流，从而保证输出完整。 请不要在生产模式使用，除非你有意输出相关日志。 ```dart dio.interceptors.add( LogInterceptor( logPrint: (o) => debugPrint(o.toString()), ), ); ``` ### 自定义拦截器 开发者可以通过继承 `Interceptor/QueuedInterceptor` 类来实现自定义拦截器。 这是一个简单的 [缓存拦截器](../example_dart/lib/custom_cache_interceptor.dart)。 ## 错误处理 当请求过程中发生错误时, Dio 会将 `Error/Exception` 包装成一个 `DioException`: ```dart try { // 404 await dio.get('https://api.pub.dev/not-exist'); } on DioException catch (e) { // The request was made and the server responded with a status code // that falls out of the range of 2xx and is also not 304. if (e.response != null) { print(e.response.data) print(e.response.headers) print(e.response.requestOptions) } else { // Something happened in setting up or sending the request that triggered an Error print(e.requestOptions) print(e.message) } } ``` ### DioException ```dart /// 错误的请求对应的配置。 RequestOptions requestOptions; /// 错误的请求对应的响应内容。如果请求未完成，响应内容可能为空。 Response? response; /// 错误的类型。 DioExceptionType type; /// 实际错误的内容。 Object? error; /// 实际错误的堆栈。 StackTrace? stackTrace; /// 错误信息。 String? message; ``` ### DioExceptionType 见 [源码](lib/src/dio_exception.dart)。 ## 使用 application/x-www-form-urlencoded 编码 默认情况下, Dio 会将请求数据（除了 `String` 类型）序列化为 JSON。 如果想要以 `application/x-www-form-urlencoded` 格式编码, 你可以设置 `contentType` : ```dart // Instance level dio.options.contentType = Headers.formUrlEncodedContentType; // or only works once dio.post( '/info', data: {'id': 5}, options: Options(contentType: Headers.formUrlEncodedContentType), ); ``` ## 发送 FormData Dio 支持发送 `FormData`, 请求数据将会以 `multipart/form-data` 方式编码, `FormData` 中可以包含一个或多个文件。 ```dart final formData = FormData.fromMap({ 'name': 'dio', 'date': DateTime.now().toIso8601String(), 'file': await MultipartFile.fromFile('./text.txt',filename: 'upload.txt') }); final response = await dio.post('/info', data: formData); ``` 你也可以指定封边 (boundary) 的名称， 封边名称会与额外的前缀和后缀一并组装成 `FormData` 的封边。 ```dart final formDataWithBoundaryName = FormData( boundaryName: 'my-boundary-name', ); ``` > 通常情况下只有 POST 方法支持发送 FormData。 这里有一个完整的 [示例](../example_dart/lib/formdata.dart)。 ### 多文件上传 多文件上传时，通过给 key 加中括号 `[]` 方式作为文件数组的标记，大多数后台也会通过 `key[]` 来读取多个文件。 然而 RFC 标准中并没有规定多文件上传必须要使用 `[]`，关键在于后台与客户端之间保持一致。 ```dart final formData = FormData.fromMap({ 'files': [ MultipartFile.fromFileSync('path/to/upload1.txt', filename: 'upload1.txt'), MultipartFile.fromFileSync('path/to/upload2.txt', filename: 'upload2.txt'), ], }); ``` 最终编码时会 key 会为 `files[]`， **如果不想添加 `[]`**，可以通过 `Formdata` 的 `files` 来构建： ```dart final formData = FormData(); formData.files.addAll([ MapEntry( 'files', MultipartFile.fromFileSync('./example/upload.txt',filename: 'upload.txt'), ), MapEntry( 'files', MultipartFile.fromFileSync('./example/upload.txt',filename: 'upload.txt'), ), ]); ``` ### 复用 `FormData` 和 `MultipartFile` 如果你在重复调用的请求中使用 `FormData` 或者 `MultipartFile`，确保你每次使用的都是新实例。 常见的错误做法是将 `FormData` 赋值给一个共享变量，在每次请求中都使用这个变量。 这样的操作会加大 **无法序列化** 的错误出现的可能性。 你可以像以下的代码一样编写你的请求以避免出现这样的错误： ```dart Future _repeatedlyRequest() async { Future createFormData() async { return FormData.fromMap({ 'name': 'dio', 'date': DateTime.now().toIso8601String(), 'file': await MultipartFile.fromFile('./text.txt',filename: 'upload.txt'), }); } await dio.post('some-url', data: await createFormData()); } ``` ## 转换器 转换器 `Transformer` 用于对请求数据和响应数据进行编解码处理。 Dio 实现了一个默认转换器 `DefaultTransformer`。 如果你想对请求和响应数据进行自定义编解码处理，可以提供自定义转换器并通过 `dio.transformer` 设置。 > `Transformer.transformRequest` 只在 `PUT`/`POST`/`PATCH` 方法中生效， > 只有这些方法可以使用请求内容体 (request body)。 > 但是 `Transformer.transformResponse` 可以用于所有请求方法的返回数据。 ### 在 Flutter 中进行设置 如果你在开发 Flutter 应用，强烈建议通过 `compute` 在单独的 isolate 中进行 JSON 解码， 从而避免在解析复杂 JSON 时导致的 UI 卡顿。 ```dart /// Map _parseAndDecode(String response) { return jsonDecode(response) as Map; } Future> parseJson(String text) { return compute(_parseAndDecode, text); } void main() { // 自定义 `jsonDecodeCallback` dio.transformer = DefaultTransformer()..jsonDecodeCallback = parseJson; runApp(MyApp()); } ``` ### 其它示例 这里有一个 [自定义 Transformer 的示例](../example_dart/lib/transformer.dart)。 ## HttpClientAdapter `HttpClientAdapter` 是 `Dio` 和 `HttpClient` 之间的桥梁。 `Dio` 实现了一套标准且强大的 API，而 `HttpClient` 则是真正发起 HTTP 请求的对象。 我们通过 `HttpClientAdapter` 将 `Dio` 和 `HttpClient` 解耦， 这样一来便可以自由定制 HTTP 请求的底层实现。 Dio 使用 `IOHttpClientAdapter` 作为原生平台默认的桥梁， `BrowserHttpClientAdapter` 作为 Web 平台的桥梁。 你可以通过 `HttpClientAdapter()` 来根据平台创建它们。 ```dart dio.httpClientAdapter = HttpClientAdapter(); ``` 如果你需要单独使用对应平台的适配器： - 对于 Web 平台 ```dart import 'package:dio/browser.dart'; // ... dio.httpClientAdapter = BrowserHttpClientAdapter(); ``` - 对于原生平台： ```dart import 'package:dio/io.dart'; // ... dio.httpClientAdapter = IOHttpClientAdapter(); ``` [示例](../example_dart/lib/adapter.dart) 中包含了一个简单的自定义桥接。 ### 设置代理 `IOHttpClientAdapter` 提供了一个 `createHttpClient` 回调来设置底层 `HttpClient` 的代理： ```dart import 'package:dio/io.dart'; void initAdapter() { dio.httpClientAdapter = IOHttpClientAdapter( createHttpClient: () { final client = HttpClient(); client.findProxy = (uri) { // 将请求代理至 localhost:8888。 // 请注意，代理会在你正在运行应用的设备上生效，而不是在宿主平台生效。 return 'PROXY localhost:8888'; }; return client; }, ); } ``` 完整的示例请查看 [这里](../example_dart/lib/proxy.dart)。 Web 平台不支持设置代理。 ### HTTPS 证书校验 HTTPS 证书验证（或公钥固定）是指确保端侧与服务器的 TLS 连接的证书是期望的证书，从而减少中间人攻击的机会。 [OWASP](https://owasp.org/www-community/controls/Certificate_and_Public_Key_Pinning) 中解释了该理论。 **服务器响应证书** 与其他方法不同，此方法使用服务器本身的证书。 ```dart void initAdapter() { const String fingerprint = 'ee5ce1dfa7a53657c545c62b65802e4272878dabd65c0aadcf85783ebb0b4d5c'; dio.httpClientAdapter = IOHttpClientAdapter( createHttpClient: () { // Don't trust any certificate just because their root cert is trusted. final HttpClient client = HttpClient(context: SecurityContext(withTrustedRoots: false)); // You can test the intermediate / root cert here. We just ignore it. client.badCertificateCallback = (cert, host, port) => true; return client; }, validateCertificate: (cert, host, port) { // Check that the cert fingerprint matches the one we expect. // We definitely require _some_ certificate. if (cert == null) { return false; } // Validate it any way you want. Here we only check that // the fingerprint matches the OpenSSL SHA256. return fingerprint == sha256.convert(cert.der).toString(); }, ); } ``` 你可以使用 OpenSSL 读取密钥的 SHA-256： ```sh openssl s_client -servername pinning-test.badssl.com -connect pinning-test.badssl.com:443 < /dev/null 2>/dev/null \ | openssl x509 -noout -fingerprint -sha256 # SHA256 Fingerprint=EE:5C:E1:DF:A7:A5:36:57:C5:45:C6:2B:65:80:2E:42:72:87:8D:AB:D6:5C:0A:AD:CF:85:78:3E:BB:0B:4D:5C # (remove the formatting, keep only lower case hex characters to match the `sha256` above) ``` **证书颁发机构验证** 当您的服务器具有自签名证书时，可以用下面的方法，但它们不适用于 AWS 或 Let's Encrypt 等第三方颁发的证书。 有两种方法可以校验证书，假设我们的后台服务使用的是自签名证书，证书格式是 PEM 格式，我们将证书的内容保存在本地字符串中， 那么我们的校验逻辑如下： ```dart void initAdapter() { String PEM = 'XXXXX'; // root certificate content dio.httpClientAdapter = IOHttpClientAdapter( createHttpClient: () { final client = HttpClient(); client.badCertificateCallback = (X509Certificate cert, String host, int port) { return cert.pem == PEM; // Verify the certificate. }; return client; }, ); } ``` 对于自签名的证书，我们也可以将其添加到本地证书信任链中， 这样证书验证时就会自动通过，而不会再走到 `badCertificateCallback` 回调中： ```dart void initAdapter() { String PEM = 'XXXXX'; // root certificate content dio.httpClientAdapter = IOHttpClientAdapter( onHttpClientCreate: (_) { final SecurityContext sc = SecurityContext(); sc.setTrustedCertificates(File(pathToTheCertificate)); final HttpClient client = HttpClient(context: sc); return client; }, ); } ``` 注意，通过 `setTrustedCertificates()` 设置的证书格式必须为 PEM 或 PKCS12， 如果证书格式为 PKCS12，则需将证书密码传入， 这样则会在代码中暴露证书密码，所以客户端证书校验不建议使用 PKCS12 格式的证书。 ## HTTP/2 支持 [dio_http2_adapter](../plugins/http2_adapter) 提供了一个支持 HTTP/2 的桥接 。 ## 请求取消 你可以通过 `CancelToken` 来取消发起的请求。 一个 `CancelToken` 可以给多个请求共用， 在共用时调用 `cancel()` 会取消对应的所有请求： ```dart final cancelToken = CancelToken(); dio.get(url, cancelToken: cancelToken).catchError((DioException error) { if (CancelToken.isCancel(error)) { print('Request canceled: ${error.message}'); } else { // handle error. } }); // Cancel the requests with "cancelled" message. token.cancel('cancelled'); ``` 完整的示例请参考 [取消示例](../example_dart/lib/cancel_request.dart). ## 继承 Dio class `Dio` 是一个拥有工厂构造函数的接口类，因此不能直接继承 `Dio`， 但是可以继承 `DioForNative` 或 `DioForBrowser`： ```dart import 'package:dio/dio.dart'; import 'package:dio/io.dart'; // 在浏览器中，导入 'package:dio/browser.dart'。 class Http extends DioForNative { Http([BaseOptions options]) : super(options) { // 构造函数执行 } } ``` 我们也可以直接实现 `Dio` 接口类 : ```dart class MyDio with DioMixin implements Dio { // ... } ``` ## Web 平台跨域资源共享 (CORS) 在 Web 平台上发送网络请求时，如果请求不是一个 [简单请求][]， 浏览器会自动向服务器发送 [CORS 预检][] (Pre-flight requests)， 用于检查服务器是否支持跨域资源共享。 你可以参考简单请求的定义修改你的请求，或者为你的服务加上 CORS 中间件进行跨域处理。 [简单请求]: https://developer.mozilla.org/zh-CN/docs/Web/HTTP/CORS#%E7%AE%80%E5%8D%95%E8%AF%B7%E6%B1%82 [CORS 预检]: https://developer.mozilla.org/zh-CN/docs/Glossary/Preflight_request ================================================ FILE: dio/README.md ================================================ # dio [![Pub](https://img.shields.io/pub/v/dio.svg)](https://pub.dev/packages/dio) [![Dev](https://img.shields.io/pub/v/dio.svg?label=dev&include_prereleases)](https://pub.dev/packages/dio) Language: English | [简体中文](README-ZH.md) A powerful HTTP networking package for Dart/Flutter, supports Global configuration, Interceptors, FormData, Request cancellation, File uploading/downloading, Timeout, Custom adapters, Transformers, etc. > Don't forget to add [#dio](https://pub.dev/packages?q=topic%3Adio) > topic to your published dio related packages! > See more: https://dart.dev/tools/pub/pubspec#topics

## Get started ### Install Add the `dio` package to your [pubspec dependencies](https://pub.dev/packages/dio/install). **Before you upgrade: Breaking changes might happen in major and minor versions of packages.
See the [Migration Guide][] for the complete breaking changes list.** [Migration Guide]: https://pub.dev/documentation/dio/latest/topics/Migration%20Guide-topic.html ### Super simple to use ```dart import 'package:dio/dio.dart'; final dio = Dio(); void getHttp() async { final response = await dio.get('https://dart.dev'); print(response); } ``` ## Awesome dio 🎉 A curated list of awesome things related to dio. ### Plugins [Plugins](https://pub.dev/documentation/dio/latest/topics/Plugins-topic.html) Welcome to submit third-party plugins and related libraries in [here](https://github.com/cfug/dio/issues/347). ## Examples ### Performing a `GET` request ```dart import 'package:dio/dio.dart'; final dio = Dio(); void request() async { Response response; response = await dio.get('/test?id=12&name=dio'); print(response.data.toString()); // The below request is the same as above. response = await dio.get( '/test', queryParameters: {'id': 12, 'name': 'dio'}, ); print(response.data.toString()); } ``` ### Performing a `POST` request ```dart response = await dio.post('/test', data: {'id': 12, 'name': 'dio'}); ``` ### Performing multiple concurrent requests ```dart List responses = await Future.wait([dio.post('/info'), dio.get('/token')]); ``` ### Downloading a file ```dart response = await dio.download( 'https://pub.dev/', (await getTemporaryDirectory()).path + 'pub.html', ); ``` ### Get response stream ```dart final rs = await dio.get( url, options: Options(responseType: ResponseType.stream), // Set the response type to `stream`. ); print(rs.data.stream); // Response stream. ``` ### Get response with bytes ```dart final rs = await Dio().get>( url, options: Options(responseType: ResponseType.bytes), // Set the response type to `bytes`. ); print(rs.data); // Type: List. ``` ### Sending a `FormData` ```dart final formData = FormData.fromMap({ 'name': 'dio', 'date': DateTime.now().toIso8601String(), }); final response = await dio.post('/info', data: formData); ``` ### Uploading multiple files to server by FormData ```dart final formData = FormData.fromMap({ 'name': 'dio', 'date': DateTime.now().toIso8601String(), 'file': await MultipartFile.fromFile('./text.txt', filename: 'upload.txt'), 'files': [ await MultipartFile.fromFile('./text1.txt', filename: 'text1.txt'), await MultipartFile.fromFile('./text2.txt', filename: 'text2.txt'), ] }); final response = await dio.post('/info', data: formData); ``` ### Listening the uploading progress ```dart final response = await dio.post( 'https://www.dtworkroom.com/doris/1/2.0.0/test', data: {'aa': 'bb' * 22}, onSendProgress: (int sent, int total) { print('$sent $total'); }, ); ``` ### Post binary data with Stream ```dart // Binary data final postData = [0, 1, 2]; await dio.post( url, data: Stream.fromIterable(postData.map((e) => [e])), // Creates a Stream>. options: Options( headers: { Headers.contentLengthHeader: postData.length, // Set the content-length. }, ), ); ``` Note: `content-length` must be set if you want to subscribe to the sending progress. See all examples code [here](example). ## Dio APIs ### Creating an instance and set default configs > It is recommended to use a singleton of `Dio` in projects, which can manage configurations like headers, base urls, > and timeouts consistently. > Here is an [example](../example_flutter_app) that use a singleton in Flutter. You can create instance of Dio with an optional `BaseOptions` object: ```dart final dio = Dio(); // With default `Options`. void configureDio() { // Set default configs dio.options.baseUrl = 'https://api.pub.dev'; dio.options.connectTimeout = Duration(seconds: 5); dio.options.receiveTimeout = Duration(seconds: 3); // Or create `Dio` with a `BaseOptions` instance. final options = BaseOptions( baseUrl: 'https://api.pub.dev', connectTimeout: Duration(seconds: 5), receiveTimeout: Duration(seconds: 3), ); final anotherDio = Dio(options); // Or clone the existing `Dio` instance with all fields. final clonedDio = dio.clone(); } ``` The core API in Dio instance is: ```dart Future> request( String path, { Object? data, Map? queryParameters, CancelToken? cancelToken, Options? options, ProgressCallback? onSendProgress, ProgressCallback? onReceiveProgress, }); ``` ```dart final response = await dio.request( '/test', data: {'id': 12, 'name': 'dio'}, options: Options(method: 'GET'), ); ``` ### Request Options There are two request options concepts in the Dio library: `BaseOptions` and `Options`. The `BaseOptions` include a set of base settings for each `Dio()`, and the `Options` describes the configuration for a single request. These options will be merged when making requests. The `Options` declaration is as follows: ```dart /// The HTTP request method. String method; /// Timeout when sending data. /// /// Throws the [DioException] with /// [DioExceptionType.sendTimeout] type when timed out. /// /// `null` or `Duration.zero` means no timeout limit. Duration? sendTimeout; /// Timeout when receiving data. /// /// The timeout represents: /// - a timeout before the connection is established /// and the first received response bytes. /// - the duration during data transfer of each byte event, /// rather than the total duration of the receiving. /// /// Throws the [DioException] with /// [DioExceptionType.receiveTimeout] type when timed out. /// /// `null` or `Duration.zero` means no timeout limit. Duration? receiveTimeout; /// Custom field that you can retrieve it later in [Interceptor], /// [Transformer] and the [Response.requestOptions] object. Map? extra; /// HTTP request headers. /// /// The keys of the header are case-insensitive, /// e.g.: `content-type` and `Content-Type` will be treated as the same key. Map? headers; /// Whether the case of header keys should be preserved. /// /// Defaults to false. /// /// This option WILL NOT take effect on these circumstances: /// - XHR ([HttpRequest]) does not support handling this explicitly. /// - The HTTP/2 standard only supports lowercase header keys. bool? preserveHeaderCase; /// The type of data that [Dio] handles with options. /// /// The default value is [ResponseType.json]. /// [Dio] will parse response string to JSON object automatically /// when the content-type of response is [Headers.jsonContentType]. /// /// See also: /// - `plain` if you want to receive the data as `String`. /// - `bytes` if you want to receive the data as the complete bytes. /// - `stream` if you want to receive the data as streamed binary bytes. ResponseType? responseType; /// The request content-type. /// /// The default `content-type` for requests will be implied by the /// [ImplyContentTypeInterceptor] according to the type of the request payload. /// The interceptor can be removed by /// [Interceptors.removeImplyContentTypeInterceptor]. String? contentType; /// Defines whether the request is considered to be successful /// with the given status code. /// The request will be treated as succeed if the callback returns true. ValidateStatus? validateStatus; /// Whether to retrieve the data if status code indicates a failed request. /// /// Defaults to true. bool? receiveDataWhenStatusError; /// See [HttpClientRequest.followRedirects]. /// /// Defaults to true. bool? followRedirects; /// The maximum number of redirects when [followRedirects] is `true`. /// [RedirectException] will be thrown if redirects exceeded the limit. /// /// Defaults to 5. int? maxRedirects; /// See [HttpClientRequest.persistentConnection]. /// /// Defaults to true. bool? persistentConnection; /// The default request encoder is [Utf8Encoder], you can set custom /// encoder by this option. RequestEncoder? requestEncoder; /// The default response decoder is [Utf8Decoder], you can set custom /// decoder by this option, it will be used in [Transformer]. ResponseDecoder? responseDecoder; /// Indicates the format of collection data in request query parameters and /// `x-www-url-encoded` body data. /// /// Defaults to [ListFormat.multi]. ListFormat? listFormat; ``` There is a complete example [here](../example_dart/lib/options.dart). ### Response The response for a request contains the following information. ```dart /// Response body. may have been transformed, please refer to [ResponseType]. T? data; /// The corresponding request info. RequestOptions requestOptions; /// HTTP status code. int? statusCode; /// Returns the reason phrase associated with the status code. /// The reason phrase must be set before the body is written /// to. Setting the reason phrase after writing to the body. String? statusMessage; /// Whether this response is a redirect. /// ** Attention **: Whether this field is available depends on whether the /// implementation of the adapter supports it or not. bool isRedirect; /// The series of redirects this connection has been through. The list will be /// empty if no redirects were followed. [redirects] will be updated both /// in the case of an automatic and a manual redirect. /// /// ** Attention **: Whether this field is available depends on whether the /// implementation of the adapter supports it or not. List redirects; /// Custom fields that only for the [Response]. Map extra; /// Response headers. Headers headers; ``` When request is succeed, you will receive the response as follows: ```dart final response = await dio.get('https://pub.dev'); print(response.data); print(response.headers); print(response.requestOptions); print(response.statusCode); ``` Be aware, the `Response.extra` is different from `RequestOptions.extra`, they are not related to each other. ### Interceptors For each dio instance, we can add one or more interceptors, by which we can intercept requests, responses, and errors before they are handled by `then` or `catchError`. ```dart dio.interceptors.add( InterceptorsWrapper( onRequest: (RequestOptions options, RequestInterceptorHandler handler) { // Do something before request is sent. // If you want to resolve the request with custom data, // you can resolve a `Response` using `handler.resolve(response)`. // If you want to reject the request with a error message, // you can reject with a `DioException` using `handler.reject(dioError)`. return handler.next(options); }, onResponse: (Response response, ResponseInterceptorHandler handler) { // Do something with response data. // If you want to reject the request with a error message, // you can reject a `DioException` object using `handler.reject(dioError)`. return handler.next(response); }, onError: (DioException error, ErrorInterceptorHandler handler) { // Do something with response error. // If you want to resolve the request with some custom data, // you can resolve a `Response` object using `handler.resolve(response)`. return handler.next(error); }, ), ); ``` Simple interceptor example: ```dart import 'package:dio/dio.dart'; class CustomInterceptors extends Interceptor { @override void onRequest(RequestOptions options, RequestInterceptorHandler handler) { print('REQUEST[${options.method}] => PATH: ${options.path}'); super.onRequest(options, handler); } @override void onResponse(Response response, ResponseInterceptorHandler handler) { print('RESPONSE[${response.statusCode}] => PATH: ${response.requestOptions.path}'); super.onResponse(response, handler); } @override Future onError(DioException err, ErrorInterceptorHandler handler) async { print('ERROR[${err.response?.statusCode}] => PATH: ${err.requestOptions.path}'); super.onError(err, handler); } } ``` #### Resolve and reject the request In all interceptors, you can interfere with their execution flow. If you want to resolve the request/response with some custom data, you can call `handler.resolve(Response)`. If you want to reject the request/response with a error message, you can call `handler.reject(dioError)` . ```dart dio.interceptors.add( InterceptorsWrapper( onRequest: (options, handler) { return handler.resolve( Response(requestOptions: options, data: 'fake data'), ); }, ), ); final response = await dio.get('/test'); print(response.data); // 'fake data' ``` #### QueuedInterceptor `Interceptor` can be executed concurrently, that is, all the requests enter the interceptor at once, rather than executing sequentially. However, in some cases we expect that requests enter the interceptor sequentially like #590. Therefore, we need to provide a mechanism for sequential access (step by step) to interceptors and `QueuedInterceptor` can solve this problem. ##### Example Because of security reasons, we need all the requests to set up a `csrfToken` in the header, if `csrfToken` does not exist, we need to request a csrfToken first, and then perform the network request, because the request csrfToken progress is asynchronous, so we need to execute this async request in request interceptor. For the complete code see [here](../example_dart/lib/queued_interceptor_crsftoken.dart). #### LogInterceptor You can apply the `LogInterceptor` to log requests and responses automatically. **Note:** `LogInterceptor` should always be the last interceptor added, otherwise modifications by following interceptors will not be logged. #### Dart ```dart dio.interceptors.add(LogInterceptor(responseBody: false)); // Do not output responses body. ``` **Note:** When using the default `logPrint` function, logs will only be printed in DEBUG mode (when the assertion is enabled). Alternatively `dart:developer`'s log can also be used to log messages (available in Flutter too). #### Flutter When using Flutter, Flutters own `debugPrint` function should be used. This ensures, that debug messages are also available via `flutter logs`. **Note:** `debugPrint` **does not mean print logs under the DEBUG mode**, it's a throttled function which helps to print full logs without truncation. Do not use it under any production environment unless you're intended to. ```dart dio.interceptors.add( LogInterceptor( logPrint: (o) => debugPrint(o.toString()), ), ); ``` #### Custom Interceptor You can customize interceptor by extending the `Interceptor/QueuedInterceptor` class. There is an example that implementing a simple cache policy: [custom cache interceptor](../example_dart/lib/custom_cache_interceptor.dart). ## Handling Errors When an error occurs, Dio will wrap the `Error/Exception` to a `DioException`: ```dart try { // 404 await dio.get('https://api.pub.dev/not-exist'); } on DioException catch (e) { // The request was made and the server responded with a status code // that falls out of the range of 2xx and is also not 304. if (e.response != null) { print(e.response.data) print(e.response.headers) print(e.response.requestOptions) } else { // Something happened in setting up or sending the request that triggered an Error print(e.requestOptions) print(e.message) } } ``` ### DioException ```dart /// The request info for the request that throws exception. RequestOptions requestOptions; /// Response info, it may be `null` if the request can't reach to the /// HTTP server, for example, occurring a DNS error, network is not available. Response? response; /// The type of the current [DioException]. DioExceptionType type; /// The original error/exception object; /// It's usually not null when `type` is [DioExceptionType.unknown]. Object? error; /// The stacktrace of the original error/exception object; /// It's usually not null when `type` is [DioExceptionType.unknown]. StackTrace? stackTrace; /// The error message that throws a [DioException]. String? message; ``` ### DioExceptionType See [the source code](lib/src/dio_exception.dart). ## Using application/x-www-form-urlencoded format By default, Dio serializes request data (except `String` type) to `JSON`. To send data in the `application/x-www-form-urlencoded` format instead: ```dart // Instance level dio.options.contentType = Headers.formUrlEncodedContentType; // or only works once dio.post( '/info', data: {'id': 5}, options: Options(contentType: Headers.formUrlEncodedContentType), ); ``` ## Sending FormData You can also send `FormData` with Dio, which will send data in the `multipart/form-data`, and it supports uploading files. ```dart final formData = FormData.fromMap({ 'name': 'dio', 'date': DateTime.now().toIso8601String(), 'file': await MultipartFile.fromFile('./text.txt', filename: 'upload.txt'), }); final response = await dio.post('/info', data: formData); ``` You can also specify your desired boundary name which will be used to construct boundaries of every `FormData` with additional prefix and suffix. ```dart final formDataWithBoundaryName = FormData( boundaryName: 'my-boundary-name', ); ``` > `FormData` is supported with the POST method typically. There is a complete example [here](../example_dart/lib/formdata.dart). ### Multiple files upload There are two ways to add multiple files to `FormData`, the only difference is that upload keys are different for array types。 ```dart final formData = FormData.fromMap({ 'files': [ MultipartFile.fromFileSync('path/to/upload1.txt', filename: 'upload1.txt'), MultipartFile.fromFileSync('path/to/upload2.txt', filename: 'upload2.txt'), ], }); ``` The upload key eventually becomes `files[]`. This is because many back-end services add a middle bracket to key when they get an array of files. **If you don't want a list literal**, you should create FormData as follows (Don't use `FormData.fromMap`): ```dart final formData = FormData(); formData.files.addAll([ MapEntry( 'files', MultipartFile.fromFileSync('./example/upload.txt',filename: 'upload.txt'), ), MapEntry( 'files', MultipartFile.fromFileSync('./example/upload.txt',filename: 'upload.txt'), ), ]); ``` ### Reuse `FormData`s and `MultipartFile`s You should make a new `FormData` or `MultipartFile` every time in repeated requests. A typical wrong behavior is setting the `FormData` as a variable and using it in every request. It can be easy for the *Cannot finalize* exceptions to occur. To avoid that, write your requests like the below code: ```dart Future _repeatedlyRequest() async { Future createFormData() async { return FormData.fromMap({ 'name': 'dio', 'date': DateTime.now().toIso8601String(), 'file': await MultipartFile.fromFile('./text.txt',filename: 'upload.txt'), }); } await dio.post('some-url', data: await createFormData()); } ``` ## Transformer `Transformer` allows changes to the request/response data before it is sent/received to/from the server. Dio has already implemented a `BackgroundTransformer` as default, which calls `jsonDecode` in an isolate if the response is larger than 50 KB. If you want to customize the transformation of request/response data, you can provide a `Transformer` by your self, and replace the `BackgroundTransformer` by setting the `dio.transformer`. > `Transformer.transformRequest` only takes effect when request with `PUT`/`POST`/`PATCH`, > they're methods that can contain the request body. > `Transformer.transformResponse` however, can be applied to all types of responses. ### Transformer example There is an example for [customizing Transformer](../example_dart/lib/transformer.dart). ## HttpClientAdapter `HttpClientAdapter` is a bridge between `Dio` and `HttpClient`. `Dio` implements standard and friendly APIs for developer. `HttpClient` is the real object that makes Http requests. We can use any `HttpClient` not just `dart:io:HttpClient` to make HTTP requests. And all we need is providing a `HttpClientAdapter`. The default `HttpClientAdapter` for Dio is `IOHttpClientAdapter` on native platforms, and `BrowserHttpClientAdapter` on the Web platform. They can be initiated by calling the `HttpClientAdapter()`. ```dart dio.httpClientAdapter = HttpClientAdapter(); ``` If you want to use platform adapters explicitly: - For the Web platform: ```dart import 'package:dio/browser.dart'; // ... dio.httpClientAdapter = BrowserHttpClientAdapter(); ``` - For native platforms: ```dart import 'package:dio/io.dart'; // ... dio.httpClientAdapter = IOHttpClientAdapter(); ``` [Here](../example_dart/lib/adapter.dart) is a simple example to custom adapter. ### Using proxy `IOHttpClientAdapter` provide a callback to set proxy to `dart:io:HttpClient`, for example: ```dart import 'package:dio/io.dart'; void initAdapter() { dio.httpClientAdapter = IOHttpClientAdapter( createHttpClient: () { final client = HttpClient(); // Config the client. client.findProxy = (uri) { // Forward all request to proxy "localhost:8888". // Be aware, the proxy should went through you running device, // not the host platform. return 'PROXY localhost:8888'; }; // You can also create a new HttpClient for Dio instead of returning, // but a client must being returned here. return client; }, ); } ``` There is a complete example [here](../example_dart/lib/proxy.dart). Web does not support to set proxy. ### HTTPS certificate verification HTTPS certificate verification (or public key pinning) refers to the process of ensuring that the certificates protecting the TLS connection to the server are the ones you expect them to be. The intention is to reduce the chance of a man-in-the-middle attack. The theory is covered by [OWASP](https://owasp.org/www-community/controls/Certificate_and_Public_Key_Pinning). _Server Response Certificate_ Unlike other methods, this one works with the certificate of the server itself. ```dart void initAdapter() { const String fingerprint = 'ee5ce1dfa7a53657c545c62b65802e4272878dabd65c0aadcf85783ebb0b4d5c'; dio.httpClientAdapter = IOHttpClientAdapter( createHttpClient: () { // Don't trust any certificate just because their root cert is trusted. final HttpClient client = HttpClient(context: SecurityContext(withTrustedRoots: false)); // You can test the intermediate / root cert here. We just ignore it. client.badCertificateCallback = (cert, host, port) => true; return client; }, validateCertificate: (cert, host, port) { // Check that the cert fingerprint matches the one we expect. // We definitely require _some_ certificate. if (cert == null) { return false; } // Validate it any way you want. Here we only check that // the fingerprint matches the OpenSSL SHA256. return fingerprint == sha256.convert(cert.der).toString(); }, ); } ``` You can use openssl to read the SHA256 value of a certificate: ```sh openssl s_client -servername pinning-test.badssl.com -connect pinning-test.badssl.com:443 < /dev/null 2>/dev/null \ | openssl x509 -noout -fingerprint -sha256 # SHA256 Fingerprint=EE:5C:E1:DF:A7:A5:36:57:C5:45:C6:2B:65:80:2E:42:72:87:8D:AB:D6:5C:0A:AD:CF:85:78:3E:BB:0B:4D:5C # (remove the formatting, keep only lower case hex characters to match the `sha256` above) ``` _Certificate Authority Verification_ These methods work well when your server has a self-signed certificate, but they don't work for certificates issued by a 3rd party like AWS or Let's Encrypt. There are two ways to verify the root of the https certificate chain provided by the server. Suppose the certificate format is PEM, the code like: ```dart void initAdapter() { String PEM = 'XXXXX'; // root certificate content dio.httpClientAdapter = IOHttpClientAdapter( createHttpClient: () { final client = HttpClient(); client.badCertificateCallback = (X509Certificate cert, String host, int port) { return cert.pem == PEM; // Verify the certificate. }; return client; }, ); } ``` Another way is creating a `SecurityContext` when create the `HttpClient`: ```dart void initAdapter() { String PEM = 'XXXXX'; // root certificate content dio.httpClientAdapter = IOHttpClientAdapter( onHttpClientCreate: (_) { final SecurityContext sc = SecurityContext(); sc.setTrustedCertificates(File(pathToTheCertificate)); final HttpClient client = HttpClient(context: sc); return client; }, ); } ``` In this way, the format of `setTrustedCertificates()` must be PEM or PKCS12. PKCS12 requires password to use, which will expose the password in the code, so it's not recommended to use in common cases. ## HTTP/2 support [dio_http2_adapter](../plugins/http2_adapter) is a Dio `HttpClientAdapter` which supports HTTP/2. ## Cancellation You can cancel a request using a `CancelToken`. One token can be shared with multiple requests. When a token's `cancel()` is invoked, all requests with this token will be cancelled. ```dart final cancelToken = CancelToken(); dio.get(url, cancelToken: cancelToken).catchError((DioException error) { if (CancelToken.isCancel(error)) { print('Request canceled: ${error.message}'); } else { // handle error. } }); // Cancel the requests with "cancelled" message. token.cancel('cancelled'); ``` There is a complete example [here](../example_dart/lib/cancel_request.dart). ## Extends Dio class `Dio` is an abstract class with factory constructor, so we don't extend `Dio` class direct. We can extend `DioForNative` or `DioForBrowser` instead, for example: ```dart import 'package:dio/dio.dart'; import 'package:dio/io.dart'; // If in browser, import 'package:dio/browser.dart'. class Http extends DioForNative { Http([BaseOptions options]) : super(options) { // do something } } ``` We can also implement a custom `Dio` client: ```dart class MyDio with DioMixin implements Dio { // ... } ``` ## Cross-Origin Resource Sharing on Web (CORS) If a request is not a [simple request][], the Web browser will send a [CORS preflight request][] that checks to see if the CORS protocol is understood and a server is aware using specific methods and headers. You can modify your requests to match the definition of simple request, or add a CORS middleware for your service to handle CORS requests.

Rename `options.merge` to `options.copyWith`. 4. Rename `DioErrorType` enums from uppercase to camel style. 5. Delete `dio.resolve` and `dio.reject` APIs (use `handler` instead in interceptors). 6. Class `BaseOptions` no longer inherits from `Options` class. 7. Change `requestStream` type of `HttpClientAdapter.fetch` from `Stream>` to `Stream`. 8. Download API: Add real uri and redirect information to headers. ================================================ FILE: dio/doc/plugins.md ================================================ | Repository | Version | Description | |--------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------| | [dio_cookie_manager](https://github.com/cfug/dio/blob/main/plugins/cookie_manager) | [![Pub](https://img.shields.io/pub/v/dio_cookie_manager.svg?label=)](https://pub.dev/packages/dio_cookie_manager) | A cookie manager for Dio | | [dio_http2_adapter](https://github.com/cfug/dio/blob/main/plugins/http2_adapter) | [![Pub](https://img.shields.io/pub/v/dio_http2_adapter.svg?label=)](https://pub.dev/packages/dio_http2_adapter) | A Dio HttpClientAdapter which support Http/2.0 | | [native_dio_adapter](https://github.com/cfug/dio/blob/main/plugins/native_dio_adapter) | [![Pub](https://img.shields.io/pub/v/native_dio_adapter.svg?label=)](https://pub.dev/packages/native_dio_adapter) | An adapter for Dio which makes use of cupertino_http and cronet_http to delegate HTTP requests to the native platform. | | [dio_smart_retry](https://github.com/rodion-m/dio_smart_retry) | [![Pub](https://img.shields.io/pub/v/dio_smart_retry.svg?label=)](https://pub.dev/packages/dio_smart_retry) | Flexible retry library for Dio | | [http_certificate_pinning](https://github.com/diefferson/http_certificate_pinning) | [![Pub](https://img.shields.io/pub/v/http_certificate_pinning.svg?label=)](https://pub.dev/packages/http_certificate_pinning) | Https Certificate pinning for Flutter | | [dio_intercept_to_curl](https://github.com/blackflamedigital/dio_intercept_to_curl) | [![Pub](https://img.shields.io/pub/v/dio_intercept_to_curl.svg?label=)](https://pub.dev/packages/dio_intercept_to_curl) | A Flutter curl-command generator for Dio. | | [dio_cache_interceptor](https://github.com/llfbandit/dio_cache_interceptor) | [![Pub](https://img.shields.io/pub/v/dio_cache_interceptor.svg?label=)](https://pub.dev/packages/dio_cache_interceptor) | Dio HTTP cache interceptor with multiple stores respecting HTTP directives (or not) | | [dio_http_cache](https://github.com/hurshi/dio-http-cache) | [![Pub](https://img.shields.io/pub/v/dio_http_cache.svg?label=)](https://pub.dev/packages/dio_http_cache) | A simple cache library for Dio like Rxcache in Android | | [pretty_dio_logger](https://github.com/Milad-Akarie/pretty_dio_logger) | [![Pub](https://img.shields.io/pub/v/pretty_dio_logger.svg?label=)](https://pub.dev/packages/pretty_dio_logger) | Pretty Dio logger is a Dio interceptor that logs network calls in a pretty, easy to read format. | | [dio_image_provider](https://github.com/ueman/image_provider) | [![Pub](https://img.shields.io/pub/v/dio_image_provider.svg?label=)](https://pub.dev/packages/dio_image_provider) | An image provider which makes use of package:dio to instead of dart:io | | [flutter_ume_kit_dio](https://github.com/cfug/flutter_ume_kits/tree/main/packages/flutter_ume_kit_dio) | [![Pub](https://img.shields.io/pub/v/flutter_ume_kit_dio.svg?label=)](https://pub.dev/packages/flutter_ume_kit_dio) | A debug kit of dio on flutter_ume | | [sentry_dio](https://github.com/getsentry/sentry-dart) | [![Pub](https://img.shields.io/pub/v/sentry_dio.svg?label=)](https://pub.dev/packages/sentry_dio) | An integration which adds support for performance tracing for the Dio package. | | [talker_dio_logger](https://github.com/Frezyx/talker/tree/master/packages/talker_dio_logger) | [![Pub](https://img.shields.io/pub/v/talker_dio_logger.svg?label=)](https://pub.dev/packages/talker_dio_logger) | Colorful and customizable dio logger with a lightweight design and talker additional functionality | ================================================ FILE: dio/example/dio.dart ================================================ import 'package:dio/dio.dart';

If you want to persist cookies, you can use the `PersistCookieJar` class, `PersistCookieJar` persists the cookies in local files, the cookies always exist unless `delete` is called explicitly. > [!NOTE] > The path for `PersistCookieJar` must be existed on devices and with write access when running in Flutter. > Use [path_provider](https://pub.dev/packages/path_provider) package to get a valid path. In Flutter: ```dart import 'package:cookie_jar/cookie_jar.dart'; import 'package:dio/dio.dart'; import 'package:dio_cookie_manager/dio_cookie_manager.dart'; import 'package:path/path' as path; Future prepareCookieManager() async { final directory = await getApplicationDocumentsDirectory(); final cookieJar = PersistCookieJar( ignoreExpires: true, storage: FileStorage(path.join(directory.path, "/.cookies/")), ); dio.interceptors.add(CookieManager(cookieJar)); } ``` ### Handling Cookies with redirect requests Redirect requests require extra configuration to parse cookies correctly. In shortly: - Set `followRedirects` to `false`. - Allow `statusCode` from `300` to `399` responses predicated as succeed. - Make further requests using the `HttpHeaders.locationHeader`. For example: ```dart void main() async { final cookieJar = CookieJar(); final dio = Dio() ..interceptors.add(CookieManager(cookieJar)) ..options.followRedirects = false ..options.validateStatus = (status) => status != null && status >= 200 && status < 400; final redirected = await dio.get('/redirection'); final response = await dio.get( redirected.headers.value(HttpHeaders.locationHeader)!, ); } ``` ### Ignores invalid cookies By default, the `CookieManager` will throw an error when parsing invalid cookies. You can enable the `ignoreInvalidCookies` option to ignore them instead. ```dart final cookieManager = CookieManager(cookieJar, ignoreInvalidCookies: true); // Or update it later. cookieManager.ignoreInvalidCookies = true; ``` ================================================ FILE: plugins/cookie_manager/analysis_options.yaml ================================================ include: ../../analysis_options.yaml ================================================ FILE: plugins/cookie_manager/dart_test.yaml ================================================ file_reporters: json: build/reports/test-results.json presets: # empty placeholders required in CI scripts all: default: min: stable: beta: ================================================ FILE: plugins/cookie_manager/dio_cookie_manager.iml ================================================ ================================================ FILE: plugins/cookie_manager/example/example.dart ================================================ import 'package:cookie_jar/cookie_jar.dart'; import 'package:dio/dio.dart'; import 'package:dio_cookie_manager/dio_cookie_manager.dart'; void main() async { final dio = Dio(); final cookieJar = CookieJar(); dio.interceptors.add(CookieManager(cookieJar)); await dio.get('https://baidu.com/'); // Print cookies print(cookieJar.loadForRequest(Uri.parse('https://baidu.com/'))); // second request with the cookie await dio.get('https://baidu.com/'); } ================================================ FILE: plugins/cookie_manager/lib/dio_cookie_manager.dart ================================================ library dio_cookie_manager; export 'src/cookie_mgr.dart'; export 'src/exception.dart'; ================================================ FILE: plugins/cookie_manager/lib/src/cookie_mgr.dart ================================================ import 'dart:async'; import 'dart:io'; import 'package:cookie_jar/cookie_jar.dart'; import 'package:dio/dio.dart'; import 'exception.dart'; const _kIsWebInterop = bool.fromEnvironment('dart.library.js_interop'); const _kIsWebUtil = bool.fromEnvironment('dart.library.js_util'); const _kIsWeb = _kIsWebInterop || _kIsWebUtil || identical(0, 0.0); /// - `(?<=)` is a positive lookbehind assertion that matches a comma (",") /// only if it's preceded by a specific pattern.

If you encounter bugs, consider fixing it by opening a PR or at least contribute a failing test case. A client for [Dio](https://pub.dev/packages/dio) which makes use of [`cupertino_http`](https://pub.dev/packages/cupertino_http) and [`cronet_http`](https://pub.dev/packages/cronet_http) to delegate HTTP requests to the native platform instead of the `dart:io` platforms. Inspired by the [Dart 2.18 release blog](https://medium.com/dartlang/dart-2-18-f4b3101f146c). ## Motivation Using the native platform implementation, rather than the socket-based [`dart:io` HttpClient](https://api.dart.dev/stable/dart-io/HttpClient-class.html) implementation, has several advantages: - It automatically supports platform features such VPNs and HTTP proxies. - It supports many more configuration options such as only allowing access through WiFi and blocking cookies. - It supports more HTTP features such as HTTP/3 and custom redirect handling. ## Get started ### Install Add the `native_dio_adapter` package to your [pubspec dependencies](https://pub.dev/packages/native_dio_adapter/install). ### Example ```dart final dioClient = Dio(); dioClient.httpClientAdapter = NativeAdapter(); ``` ### Use embedded Cronet Starting from `cronet_http` v1.2.0, you can to use the embedded Cronet implementation using a simple configuration with `dart-define`. See https://pub.dev/packages/cronet_http#use-embedded-cronet for more details. ## 📣 About the author - [![Twitter Follow](https://img.shields.io/twitter/follow/ue_man?style=social)](https://twitter.com/ue_man) - [![GitHub followers](https://img.shields.io/github/followers/ueman?style=social)](https://github.com/ueman) ================================================ FILE: plugins/native_dio_adapter/analysis_options.yaml ================================================ include: ../../analysis_options.yaml analyzer: language: strict-raw-types: true strict-casts: true strict-inference: true ================================================ FILE: plugins/native_dio_adapter/example/.gitignore ================================================ # Miscellaneous *.class *.log *.pyc *.swp .DS_Store .atom/ .buildlog/ .history .svn/ migrate_working_dir/ # IntelliJ related *.iml *.ipr *.iws .idea/ # The .vscode folder contains launch configuration and tasks you configure in # VS Code which you may wish to be included in version control, so this line # is commented out by default. #.vscode/ # Flutter/Dart/Pub related **/doc/api/ **/ios/Flutter/.last_build_id .dart_tool/ .flutter-plugins .flutter-plugins-dependencies .packages .pub-cache/ .pub/ /build/ # Symbolication related app.*.symbols # Obfuscation related app.*.map.json # Android Studio will place build artifacts here /android/app/debug /android/app/profile /android/app/release ================================================ FILE: plugins/native_dio_adapter/example/analysis_options.yaml ================================================ # This file configures the analyzer, which statically analyzes Dart code to # check for errors, warnings, and lints. # # The issues identified by the analyzer are surfaced in the UI of Dart-enabled # IDEs (https://dart.dev/tools#ides-and-editors).

Users should upgrade the adapter with `dart pub upgrade` or `flutter pub upgrade` to use the WASM-supported version. ## 1.0.1 - Improves warning logs on the Web platform. ## 1.0.0 - Split the Web ability from the `package:dio`. ================================================ FILE: plugins/web_adapter/LICENSE ================================================ MIT License Copyright (c) 2018 Wen Du (wendux) Copyright (c) 2022 The CFUG Team Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
