// 云函数入口文件
const cloud = require('wx-server-sdk')
const mysql=require('mysql2/promise')
cloud.init()
// 云函数入口函数
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
}
错误如下：
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;

请教一下：
在“host:'mysql57.rdsmj85epr606zi.rds.bj.baidubce.com',”中，
这里的host可以使用IP地址吗？
刚刚，我重新上传一个新的云函数，同样的代码，npm install mysql2,居然神奇的成功了。
我认为，是因为前一个云函数，我曾经删去过一次目录的因素。
还是很谢谢你给我带来的好运。
也祝你事业兴旺！
Cannot read property 'execute' of undefined
这个js语法错误 应该是 connection 是 undefined吧
