一、app.json配置属性之debug

可以在开发者工具中开启 debug 模式，在开发者工具的控制台面板，调试信息以 info 的形式给出，其信息有 Page 的注册，页面路由，数据更新，事件触发等。可以帮助开发者快速定位一些常见的问题。

二、debug配置案例

首先我们打开微信开发者工具、并找到项目文件中的app.json

添加"debug":true属性

{
  "entryPagePath": "pages/index/index",
  "pages": [
    "pages/index/index",
    "pages/getOpenId/index",
    "pages/getMiniProgramCode/index",
    "pages/deployService/index",
    "pages/createCollection/index",
    "pages/uploadFile/index",
    "pages/selectRecord/index",
    "pages/updateRecord/index",
    "pages/updateRecordResult/index",
    "pages/updateRecordSuccess/index",
    "pages/sumRecord/index",
    "pages/sumRecordResult/index"
  ],
  "window": {
    "backgroundColor": "#F6F6F6",
    "backgroundTextStyle": "light",
    "navigationBarBackgroundColor": "#F6F6F6",
    "navigationBarTitleText": "云开发 QuickStart",
    "navigationBarTextStyle": "black"
  },
  "tabBar": {
    "list": [
      {
        "pagePath": "pages/index/index",
        "text": "首页"
      },
      {
        "pagePath": "pages/getOpenId/index",
        "text": "看资讯"
      },
      {
        "pagePath": "pages/getMiniProgramCode/index",
        "text": "我的"
      }
    ],
    "backgroundColor": "#fff",
    "color": "#000",
    "selectedColor": "#0286f1"
  },
  "networkTimeout": {
    "request": 10000,
    "downloadFile": 10000,
    "connectSocket": 10000,
    "uploadFile": 10000
  },
  "sitemapLocation": "sitemap.json",
  "style": "v2",
  "debug":true
}

然后再点击任何一个路由页面，中点击“console”这个菜单，就可以看到菜单所触发的一些数据更新，路由注册等信息。
