使用 Promise 解决小程序页面因为需要app.js onLaunch 参数导致的请求失败
app.js onLaunch 的代码
"use strict";

}) updateManager.onUpdateReady(function() {
wx.showModal({

success(res) {
if (res.confirm) {
// 新的版本已经下载好，调用 applyUpdate 应用新版本并重启
updateManager.applyUpdate()
}
}
})
}) updateManager.onUpdateFailed(function() {
// 新版本下载失败
wx.showModal({
title: '提示',
content: '新版本下载失败',
showCancel: false

小程序页面的代码 onlaod的事件得写在 Promise 的then方法里
onLoad: function() {
var _this = this;
app.toLogin().then(function(res) {
console.log('登录后');
console.log(res);
if (app.globalData.shopid) {
_this.toGetKanBanData();
_this.toGetSaleDetail();
_this.toGuestOrderDetail();
}
});
},
