// 云函數入口文件

const cloud = require('wx-server-sdk')

const mysql=require('mysql2/promise')

cloud.init()

// 云函數入口函數

exports.main = async (event, context) => {

const connection=await mysql.createConnection({

host:'mysql57.rdsmj85epr606zi.rds.bj.baidubce.com',

user:'sam',

database:'samMYSQL',

password:'xxxxxxxx',

})

const [rows, fields] = await connection.execute('SELECT version();')

return rows

}

錯誤如下：

WAService.js:1 Uncaught (in promise) Error: errCode: -404011 cloud function execution error | errMsg: cloud.callFunction:fail requestID 8a0ca2a7-f0f0-11e9-af3a-525400192d0e, cloud function service error code -504002, error message Cannot read property 'execute' of undefined; at cloud.callFunction api;
