一、app.js

// app.jslet userInfo =wx.getStorageSync("userInfo") || {} //用户信息let isLogin = JSON.stringify(userInfo) != "{}" //用户登录状态App({    onLaunch: function () {    if (!wx.cloud) {      console.error('请使用 2.2.3 或以上的基础库以使用云能力');    } else {      wx.cloud.init({        // env 参数说明：        //   env 参数决定接下来小程序发起的云开发调用（wx.cloud.xxx）会默认请求到哪个云环境的资源        //   此处请填入环境 ID, 环境 ID 可打开云控制台查看        //   如不填则使用默认环境（第一个创建的环境）        env: 'cloud1-0g26459e75827aa8',        traceUser: true,      });    }    this.globalData = {      // 购物车商品数量      totalCartCount: 0,      userInfo: userInfo,      isLogin: isLogin    }       console.log(this.globalData)    //this.globalData = {};  }});

二、修改json

1、新建页面

目前主要的有首页、预约、关于、个人中心

    "pages": [      "pages/index/index",      "pages/reservation/reservation",      "pages/about/about",      "pages/mine/mine"    ],

2、修改tab设置

 "tabBar": {        "selectedColor": "#ff4444",        "color": "#808080",        "list": [            {                "pagePath": "pages/index/index",                "text": "首页",                "iconPath": "images/tabbar/homepage.png",                "selectedIconPath": "images/tabbar/homepage-sel.png"            },            {                "pagePath": "pages/reservation/reservation",                "text": "预约",                "iconPath": "images/tabbar/order.png",                "selectedIconPath": "images/tabbar/order-sel.png"            },            {                "pagePath": "pages/about/about",                "text": "关于",                "iconPath": "images/tabbar/about.png",                "selectedIconPath": "images/tabbar/about-sel.png"            },            {                "pagePath": "pages/mine/mine",                "text": "我的",                "iconPath": "images/tabbar/user.png",                "selectedIconPath": "images/tabbar/user-sel.png"            }        ]    },

3、修改 app.json全局的默认窗口配置

"window": {    "backgroundColor": "#F6F6F6",    "backgroundTextStyle": "light",    "navigationBarBackgroundColor": "#F6F6F6",    "navigationBarTitleText": "贝贝和亲亲",    "navigationBarTextStyle": "black"  }

三、修改全局样式app.wxss

/**app.wxss**/page{  width:100%;  padding: 0;  margin: 0;  height: 100%;  font-family:  "PingFang SC", -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;  background-color: #f2f2f2;}.container {  display: flex;  flex-direction: column;  align-items: center;  box-sizing: border-box;}
