版本业务服务器示例。示例需要和[微信小程序客户端示例](https://github.com/tencentyun/weapp-client-demo)配合一起使用。\n\n## 运行示例\n\n选择合适的方式[部署 Wafer](https://github.com/tencentyun/wafer/wiki#%E9%83%A8%E7%BD%B2%E6%96%B9%E5%BC%8F)，并按照[小程序创建资源配置指引](https://github.com/tencentyun/weapp-doc)进行操作，可以得到运行本示例所需的资源和服务。请参考以下配置。\n\n- SDK 配置文件：`/etc/qcloud/sdk.config`\n- 示例代码部署目录：`/data/release/php-weapp-demo`\n- 运行示例的 nginx 配置文件: `/etc/nginx/conf.d/php-weapp-demo.conf`\n- PHP 版本：`v5.6.27`\n- composer 版本：`v1.2.1`\n- nginx 版本：`v1.10.1`\n\n## 项目结构\n\n```\nDemo\n├── application\n│   ├── business\n│ │   └── ChatTunnelHandler.php\n│   ├── cache\n│   ├── config\n│   ├── controllers\n│ │   ├── Welcome.php\n│ │   ├──

框架制作。其中，`index.php` 是 启动文件，`install_qcloud_sdk.php` 用于初始化 SDK 配置，配置从文件 `/etc/qcloud/sdk.config` 中读取。配置文件包含如下配置项：\n\n```json\n{\n \"serverHost\": \"业务服务器的主机名\",\n \"authServerUrl\": \"鉴权服务器地址\",\n \"tunnelServerUrl\": \"信道服务器地址\",\n \"tunnelSignatureKey\": \"和信道服务器通信的签名密钥\",\n \"networkTimeout\": 30000\n}\n```\n其中 `networkTimeout` 为超时时间，单位是**毫秒**。\n\n`composer.json` 文件中声明了对 SDK 的依赖，可执行命令 `composer install` 安装依赖。\n\n`application/controllers/` 目录包含了示例用到的4个路由，路由和处理文件映射关系如下：\n\n```\n// 首页指引\n/ => application/controllers/Welcome.php\n\n// 登录\n/login => application/controllers/Login.php\n\n// 获取微信用户信息\n/user => application/controllers/User.php\n\n// 处理信道请求\n/tunnel => application/controllers/Tunnel.php\n```\n\n`application/business/ChatTunnelHandler.php` 是业务处理信道请求的示例代码。\n\n`application/helpers/general_helper.php` 包含简单的 `debug` 方法用于打印日志。\n\n\n## 更新 SDK 版本\n进入目录 `/data/release/php-weapp-demo`，然后执行命令 `composer update` 即可。\n\n\n## 如果在demo基础上开发\n将自己开发的接口放到如下目录下即可生效\n/data/release/php-weapp-demo/application/controllers/\n\n## 重启服务：\n        service php-fpm
