如何利用node實現傳送QQ郵箱驗證碼

let connect = require('connect'),         // 引入connect模組
    bodyParser = require('body-parser'),  // 引入body-parser解析模組
    nodemailer = require('nodemailer');   // 引入nodemailer模組

async function sendMail(text,receive) {
	let user = "703669046@qq.com";//自己的郵箱
	let pass = "sfsdfsdfsggxcew"; //qq郵箱授權碼
	let to = `${receive}@qq.com`; //對方的郵箱
	let transporter = nodemailer.createTransport({
		host: "smtp.qq.com",
		port: 587,
		secure: false,
		auth: {
			user: user, // 使用者賬號
			pass: pass, //授權碼,通過QQ獲取
		},
	});
	let info = await transporter.sendMail({
		from: `測試node傳送郵箱<${user}>驗證碼`, // sender address
		to: `測試驗證碼<${to}>`, // list of receivers
		subject: "測試驗證碼", // Subject line
		text: text, // plain text body
	});
}

var app = connect()
	.use(bodyParser.json())   //JSON解析
	.use(bodyParser.urlencoded({ extended: true }))
	//use()方法還有一個可選的路徑字串，對傳入請求的URL的開始匹配。
	//use方法來維護一箇中介軟體佇列

	.use(function (req, res, next) {
		//跨域處理
		// Website you wish to allow to connect
		res.setHeader('Access-Control-Allow-Origin', '*');  //允許任何源
		// Request methods you wish to allow
		res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');  //允許任何方法
		// Request headers you wish to allow
		res.setHeader('Access-Control-Allow-Headers', '*');   //允許任何型別
		res.writeHead(200, { "Content-Type": "text/plain;charset=utf-8" });    //utf-8轉碼
		next();  //next 方法就是一個遞迴呼叫
	})

	.use('/emails', function (req, res, next) {
		let qqEmail= req.body.email;
		var obj = {
			code:Math.ceil(Math.random()*1000)
		};
		let text=`驗證碼：${obj.code}.您正在使用登入功能，驗證碼提供他人可能導致賬號被盜，請勿轉發或洩漏`
		sendMail(text,qqEmail)
		res.end(JSON.stringify(obj))
		next();
	})

.listen(3331);
