## Intro 利用有赞云和有赞微小店实现个人收款解决方案, 提供如下两个服务: * 代理简化生成收款二维码的 API，支持微信支付宝扫描付款 * 接收有赞云的交易消息推送并处理(需要二次请求交易详情)，简化订单状态通知到指定的服务器 核心原理是提供了一个支付中转层，将自有商户订单与有赞云的订单绑定起来，实现支付状态更新 为什么做成单独的服务: * 方便对接任何系统 * 状态推送可以更灵活的自定义 * 单独服务模式维护减少对原有系统影响 ## Usage ### 有赞云端 * 注册[有赞云](https://console.youzanyun.com/register) 开发者 * 创建[有赞微小店](https://h5.youzan.com/v2/index/wxdpc) 并扫码下载相应 APP 便于后续管理资金，注意这个小店在有赞后台看不到，只有 APP 可见 * 应用授权-有赞云控制台创建自用型应用并授权刚创建的店铺，在[推送服务]设置中设置推送网址*http://www.example.com/api/status* , 同时勾选下方的交易消息选项。 ### 本服务 * 启动服务配置环境参数，复制`envrc.sample`为`envrc`并填写 其中: `YOUZANYUN_CLIENT_ID`: 有赞云应用的 client_id `YOUZANYUN_CLIENT_SECRET`: 有赞云应用的 client_secret `YOUZAN_KDT_ID`: 有赞云应用绑定的微小店 ID `SELF_SECRET`: 自有订单系统接收本服务推送数据的加盐 secret `PUSH_API`: 自有订单系统接收本服务推送数据的地址 ``` npm run start // 启动服务 npm run list // 查看服务列表及状态 npm run stop // 停止服务 ``` * 提供公网服务，请使用 Nginx 代理至 Node Server，这样能够让有赞推送消息到达推送网址 ### 自有订单系统端 * 接入自有商店订单系统，支付时请求服务生成收款二维码 * 接口地址示例: `http://www.example.com/api/payment/qrcode` * 调用方法 `POST application/json` * 请求数据 `name`: 商品名, `price`: 价格(分), `order_id`: 自有系统的订单号 * 返回数据 * 1. 正常情况 `qr_id`: 二维码 ID; `qr_url`: 有赞系统内支付地址(不推荐使用，需要付费者注册有赞); `qr_code`: Base64 图片数据，可直接作为 img 的 src 使用 * 2. 异常情况 `null` ```curl curl -X POST -H 'Content-type: application/json' --data '{"name":"test name", "price": 1, "order_id": "your orderid"}' http://www.example.com/api/payment/qrcode ``` * 接收状态推送自有订单系统提供一个`PUSH_API`地址接收数据推送，数据格式如下: ```json { "tradeNo": "E20180201105656001353613-6377801", "orderId": "1515174485676262", "payment": 10, "status": "TRADE_SUCCESS", "sign": "c857c0f8d52ae9713a77b5c07dda93dc", "time": "1517457474" } ``` 其中 sign 是`time`,`tradeNo`,`orderId`,`payment`,`status`,`SELF_SECRET`使用"|"拼接字符串的 MD5 特征值，请在状态接收端按此逻辑进行校验数据合法性 此外 status 的 enum 如下: ```typescript enum YZBusinessStatus { // 等待买家付款 WAIT_BUYER_PAY = "WAIT_BUYER_PAY", // 待确认，包括（待成团：拼团订单、待接单：外卖订单） WAIT_CONFIRM = "WAIT_CONFIRM", // 等待卖家发货，即:买家已付款 WAIT_SELLER_SEND_GOODS = "WAIT_SELLER_SEND_GOODS", // 等待买家确认收货,即:卖家已发货 WAIT_BUYER_CONFIRM_GOODS = "WAIT_BUYER_CONFIRM_GOODS", // 买家已签收 TRADE_BUYER_SIGNED = "TRADE_BUYER_SIGNED", // 交易成功 TRADE_SUCCESS = "TRADE_SUCCESS", // 交易关闭 TRADE_CLOSED = "TRADE_CLOSED" } ``` 一般处理`TRADE_SUCCESS`和`TRADE_CLOSED`即可，返回 200 状态表示处理成功 ## TODO * [ ] 推送失败重推 ================================================ FILE: db/.gitkeep ================================================ ================================================ FILE: envrc.sample ================================================ YOUZANYUN_CLIENT_ID= YOUZANYUN_CLIENT_SECRET= YOUZAN_KDT_ID= SELF_SECRET= PUSH_API=http://www.example1.com;http://www.example2.com ================================================ FILE: package.json ================================================ { "name": "youzanpayportal", "version": "1.0.0", "description": "", "main": "index.js", "repository": "git@github.com:thundernet8/YouzanPayPortal.git", "author": "WuXueqian ", "license": "MIT", "scripts": { "build": "rimraf dist && tsc", "start": "mkdirp logs && npm run build && cross-env NODE_ENV=production forever start dist/app.js", "start:o": "cross-env NODE_ENV=production forever start dist/app.js", "stop": "forever stop dist/app.js", "start:dev": "mkdirp logs && cross-env NODE_ENV=development node dist/app.js", "list": "forever list", "lint": "npm run lint:ts", "lint:ts": "tslint -e node_modules typings -c .tslintrc.json src/**/*.tsx", "lint-staged": "lint-staged", "lint-staged:ts": "tslint --fix -c .tslintrc.json", "format": "prettier --write" }, "lint-staged": { "src/**/*.{ts,tsx}": ["format", "lint-staged:ts", "git add"] }, "pre-commit": "lint-staged", "devDependencies": { "@types/koa": "^2.0.43", "@types/node": "^9.4.0", "cross-env": "^5.1.3", "lint-staged": "^6.1.0", "mkdirp": "^0.5.1", "pre-commit": "^1.2.2", "prettier": "^1.10.2", "rimraf": "^2.6.2", "tslint": "^5.9.1", "tslint-eslint-rules": "^4.1.1", "typescript": "^2.6.2" }, "dependencies": { "@koa/cors": "^2.2.1", "axios": "^0.17.1", "dotenv": "^5.0.0", "koa": "^2.4.1", "koa-bodyparser": "^4.2.0", "koa-compress": "^2.0.0", "koa-router": "^7.3.0", "moment": "^2.20.1", "sqlite3": "^3.1.13", "winston": "^3.0.0-rc1", "yz-open-sdk-nodejs": "^1.0.2" }, "engines": { "node": ">=8.0.0" } } ================================================ FILE: src/app.ts ================================================ import * as Koa from "koa";
