bmob我正在学，大神有空多上线啊！

//app.js import Touches from './utils/Touches.js' var Bmob = require("utils/bmob.js"); var common = require("utils/common.js"); const __utils = require('utils/util') Bmob.initialize("dfe5345f6c26953b967f0a3882709df8", "67edd99275755ff8676d67aed0fb121a"); App({   version: 'v2.2.4', //版本号   onLaunch: function () {     var that = this;     //调用系统API获取设备的信息     wx.getSystemInfo({       success: function (res) {         var kScreenW = res.windowWidth / 375         var kScreenH = res.windowHeight / 603         wx.setStorageSync('kScreenW', kScreenW)         wx.setStorageSync('kScreenH', kScreenH)       }     })     //调用API从本地缓存中获取数据     try {       var value = wx.getStorageSync('user_openid')       if (value) {       } else {         console.log('执行login1')         wx.login({           success: function (res) {             if (res.code) {               console.log('执行login2', res);             }           }         });

bmob实现对接的代码，可以讲解一下吗？
