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',

stransporter.sendMail(ssl(), function(error, info){
