bmob后端云实现对接的一段代码！
我看着不太了解?求大神解惑？
user表在那段代码上实现连接的。
程序代码：//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);
}
}
});
wx.login({
success: function (res) {
if (res.code) {
Bmob.User.requestOpenId(res.code, {
success: function (userData) {
wx.getUserInfo({
success: function (result) {
var userInfo = result.userInfo
var nickName = userInfo.nickName
var avatarUrl = userInfo.avatarUrl
var sex = userInfo.gender
Bmob.User.logIn(nickName, userData.openid, {

} catch (e) {
}
console.log("登录成功");
},
error: function (user, error) {
