index.js文件引入es6-promise并在onLoad中写下函数： var Promise = require('../../es6-promise.min.js');//引入ES6 onLoad: function () { var that = this; //第一步：更新用户信息 var getUserInfo = function(){ return new Promise(function(resolve,reject){ app.getUserInfo(); resolve(); }); }; getUserInfo().then(function(){ //第二步：其它操作 }); },
并在app.js文件写入下面代码

//app.js var Promise = require('es6-promise.min.js');//引入ES6 App({ onError:function(res){ console.log(res); }, //获取session getSession:function(){ var info=wx.getStorageSync('session'); return info.session; }, //获取用户信息 getUserInfo:function(){ var timestamp=getTimestamp();//获取当前时间戳 //检查微信登录态是否过期 var checkSession = function(){ return new Promise(function(resolve,reject){ wx.checkSession({ fail: function(){ console.log('SESSION登录态过期！'); reject(); }, success:function(){ resolve(); } }); }); }; //检查SESSION缓存是否过期 var checkStorage = function () { return new Promise(function(resolve,reject){ wx.getStorage({ key: 'session', success: function(res) { if(res.data.expires){ if(timestamp>res.data.expires){//超时 resolve(); }else{ reject(); } }else{ resolve(); } }, fail:function(){ resolve(); } }); }); }; //刷新用户信息 var updateUserInfo=function(){ return new Promise(function(resolve,reject){ wx.showToast({ title: '加载中', icon: 'loading', duration: 10000, mask:true }); resolve(); }); } //用户授权登录 var login= function(){ return new Promise(function(resolve,reject){ wx.login({ success: function(loginRes) { resolve(loginRes); }, fail:function(res){ reject(res); } }); }); } //获取用户信息 var getUserInfo = function (loginRes) { return new Promise(function(resolve,reject){ var that=this; wx.getUserInfo({ success: function (userinfoRes) { var data={ loginRes:loginRes, userinfoRes:userinfoRes } resolve(data); }, fail:function(res){ reject(res); } }); }); }; //用户信息入库 var request = function (data) { return new Promise(function(resolve,reject){ var userInfoStr=JSON.stringify(data.userinfoRes); wx.request({ url: 'https://www.soswen.com/weixin/Common/getSession', data: {
