一.app.json

使用app.json文件来对微信小程序进行全局配置，决定页面文件的路径、窗口表现、设置网络超时时间、设置多 tab 等.

注意在.json不能注释，否则会出错。

二.工具栏tabBar

如果我们的小程序是一个多 tab 应用（客户端窗口的底部或顶部有 tab 栏可以切换页面），那么我们可以通过 tabBar 配置项指定 tab 栏的表现，以及 tab 切换时显示的对应页面。

tabBar 是一个数组，只能配置最少2个、最多5个 tab，tab 按数组的顺序排序

app.json中

{  "pages": ["pages/index/index",     "pages/coming/coming",     "pages/search/search",     "pages/top/top"    ],  "window": {   "navigationBarBackgroundColor": "#47a86c",   "navigationBarTextStyle": "white",   "navigationBarTitleText": "小程序案例",   "backgroundColor": "#fff",   "backgroundTextStyle": "dark"  },  "tabBar": {   "color": "#686868",   "selectedColor": "#47a86c",   "backgroundColor": "#fff",   "list": [{    "pagePath": "pages/index/index",    "iconPath": "dist/images/popular_icon.png",    "selectedIconPath": "dist/images/popular_active_icon.png",    "text": "热映"   },   {    "pagePath": "pages/coming/coming",    "iconPath": "dist/images/coming_icon.png",    "selectedIconPath": "dist/images/coming_active_icon.png",    "text": "待映"   },   {    "pagePath": "pages/search/search",    "iconPath": "dist/images/search_icon.png",    "selectedIconPath": "dist/images/search_active_icon.png",    "text": "搜索"   },   {    "pagePath": "pages/top/top",    "iconPath": "dist/images/top_icon.png",    "selectedIconPath": "dist/images/top_active_icon.png",    "text": "口碑"   }]  },  "networkTimeout": {   "request": 10000,   "downloadFile": 10000  },  "debug": true }
