小程序使用async/await 来处理异步 regeneratorRuntime     https://github.com/facebook/regenerator/blob/master/packages/regenerator-runtime/runtime.js 详细看代码片段 https://developers.weixin.qq.com/s/FlIPCOmw7P3c //引入编译模块 const regeneratorRuntime =require("../libs/regeneratorRuntime.js")   const promisify = require('../libs/promisify.js'); //微信 API，转成返回 Promise 的接口 云开发API的有Promise 风格 不需要再转了 const getUserInfo= promisify(wx.getUserInfo); const login = promisify(wx.login); wx.cloud.init();   Page({ data: {   }, onLoad: async function () {   console.log(this)   const user = await getUserInfo(); console.log("onLoad user",user) const code = await login(); console.log("onLoad code",code);   const res = await wx.cloud.database().collection('todos').where({ _openid: 'xxx'  }).get(); console.log("onLoad res", res) }, onShow: async function(){ const user = await getUserInfo(); console.log("onshow", user)   } })
