Cloud API isn't enabled, please call wx.cloud.init first 這個(gè)錯(cuò)誤的意思就是云環(huán)境還沒有初始化就調(diào)用其它的云api了，因此需要先初始化，也就是讓我們先 wx.cloud.init() 進(jìn)行初始化，最簡(jiǎn)單的辦法就是直接在最前面初始化，代碼如下：（只需要關(guān)注第3~9行即可）

import User from './model/user' import $ from './utils/tool'//請(qǐng)關(guān)注下面的，上面兩行與該問題無(wú)關(guān) wx.cloud.init({env: 'zaiyi-3ggp5zmqe2dd21e7', //填上你的云開發(fā)環(huán)境idtraceUser: true, }) const db = wx.cloud.database() //請(qǐng)關(guān)注上面的，下面與該問題無(wú)關(guān)App({initUiGlobal() {return new Promise(resolve => {wx.getSystemInfo({success: e => {this.globalData.StatusBar = e.statusBarHeightthis.globalData.screenHeight = e.screenHeightconst capsule = wx.getMenuButtonBoundingClientRect()if (capsule) {this.globalData.Custom = capsulethis.globalData.CustomBar = capsule.bottom + capsule.top - e.statusBarHeight} else {this.globalData.CustomBar = e.statusBarHeight + 50}},complete: resolve})})},async login() {$.loading()const user = new User()wx.cloud.callFunction({name: 'getOpenid', // 對(duì)應(yīng)云函數(shù)名complete: res => {console.log(res.result.event.userInfo.openId)this.globalData.openid = res.result.event.userInfo.openIddb.collection('user').where({_openid:res.result.event.userInfo.openId}).get().then(res => {console.log(res.data.length)if(res.data.length == 0){user.register()}})}})$.hideLoading()},async onLaunch() {await this.initUiGlobal()this.login()},globalData: {StatusBar: null,Custom: null,CustomBar: null,screenHeight: null,env: 'zaiyi-3ggp5zmqe2dd21e7',openid: ''} })
