extAppid 的开发调试

为了方便第三方平台的开发者引入 extAppid 的开发调试工作，需要引入 ext.json 的概念。

ext.json 是一个配置文件，放置在小程序项目的根目录下。

以下是一个包含了所有配置选项的 ext.json ：

{
  "extEnable": true,
  "extAppid": "wxf9c4501a76931b33",
  "directCommit": false,
  "ext": {
    "name": "wechat",
    "attr": {
      "host": "open.weixin.qq.com",
      "users": [
        "user_1",
        "user_2"
      ]
    }
  },
  "extPages": {
    "pages/logs/logs": {
      "navigationBarTitleText": "logs"
    }
  },
  "window":{
    "backgroundTextStyle":"light",
    "navigationBarBackgroundColor": "#fff",
    "navigationBarTitleText": "Demo",
    "navigationBarTextStyle":"black"
  },
  "tabBar": {
    "list": [{
      "pagePath": "pages/index/index",
      "text": "首页"
    }, {
      "pagePath": "pages/logs/logs",
      "text": "日志"
    }]
  },
  "networkTimeout": {
    "request": 10000,
    "downloadFile": 10000
  },
  {
  "plugins": {
    "myPlugin": {
      "version": "1.0.0",
      "provider": "wxidxxxxxxxxxxxxxxxx"
    }
  }
}
}
