Node.js实现发送邮件功能

var nodemailer = require("nodemailer");var mailTitle='http://handsupowo.pl/：Releases HandsUp Info';var child_process = require('child_process');var fs= require('fs'); child_process.execFile('phantomjs',['HandsupInfo.js'],function (err, result) {console.log("download over");}); setTimeout(function() {readFile();    }, 20000); function readFile(){   console.log('--------ReadFile--------');   fs.readFile('DownLoadUrl.txt','utf-8',function(err,data){    if(err){         }else{      sendSSLMail(data);    }  }) } function sendSSLMail(mailContent){var stransporter = nodemailer.createTransport({  host: '填mailhost',  secureConnection: true, // use SSL  port: 465, // port  auth: {    user: 'username',    pass: 'userpwd'  }}); function ssl(){  var mailOptions = {    from: '"2017 New HandsUp Info" <SponsorChecker@intasect.co.jp>',    to: '1598828268@qq.com',    cc:'hellomusic1993@qq.com',    subject: mailTitle,    text: mailContent,           attachments:[    {     filename : 'HandsupInfo.png',     path: 'HandsupInfo.png'     }, {     filename : 'HandsupInfo.html',     path: 'HandsupInfo.html'     },{     filename : 'DownLoadUrl.txt',     path: 'DownLoadUrl.txt'     }  ]  }   return mailOptions;} stransporter.sendMail(ssl(), function(error, info){  if(error){    console.log(error);  }else{    console.log('Message sent: ' + info.response);  }});}
