Cloud API isn't enabled, please call wx.cloud.init first 这个错误的意思就是云环境还没有初始化就调用其它的云api了，因此需要先初始化，也就是让我们先 wx.cloud.init() 进行初始化，最简单的办法就是直接在最前面初始化，代码如下：（只需要关注第3~9行即可）
import User from './model/user' import $ from './utils/tool' //请关注下面的，上面两行与该问题无关 wx.cloud.init({ env: 'zaiyi-3ggp5zmqe2dd21e7', //填上你的云开发环境id traceUser: true, }) const db = wx.cloud.database() //请关注上面的，下面与该问题无关 App({ initUiGlobal() { return new Promise(resolve => { wx.getSystemInfo({ success: e => { this.globalData.StatusBar = e.statusBarHeight this.globalData.screenHeight = e.screenHeight const capsule = wx.getMenuButtonBoundingClientRect() if (capsule) { this.globalData.Custom = capsule this.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', // 对应云函数名 complete: res => { console.log(res.result.event.userInfo.openId) this.globalData.openid = res.result.event.userInfo.openId db.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: '' } })
