微信小程序如何与云服务器通信

// 云函数入口文件
const cloud = require('wx-server-sdk')
cloud.init()

exports.main = async (event, context) => {
  return {
    sum: event.a + event.b
  }
}

wx.cloud.callFunction({
  name: 'add',
  data: {
    a: 1,
    b: 2
  },
  success: res => {
    console.log(res.result.sum) // 输出 3
  },
  fail: console.error
})

const db = wx.cloud.database()
const _ = db.command

db.collection('users').add({
  data: {
    name: 'John Doe',
    age: 30
  },
  success: res => {
    console.log('添加成功', res)
  },
  fail: console.error
})

wx.request({
  url: 'https://your-server.com/api',
  timeout: 10000, // 设置超时时间为10秒
  success: res => {
    console.log(res.data)
  },
  fail: err => {
    console.error('请求失败', err)
  }
})

{
  "read": true,
  "write": "auth != null"
}
