使用 Heroku 调度作业节点 JS

Question

我正在尝试使用 heroku 进行计划工作。

我用了 cron npm 这个为什么

#!/usr/bin/env node
var mongoose = require('mongoose');
var nodemailer = require('nodemailer');
var myNoti = require('./models/notificationSchema');
var mongoose = require('mongoose');
var CronJob = require('cron').CronJob;
config = {
    mongoUrl:'mongodb://<myuser>:<mypass>@XXXX.mlab.com:XXXX/XXX'
};

new CronJob('38  00 * * *', function() {
  console.log('You will see this message every second');
function sendMail()
{
  //The server option auto_reconnect is defaulted to true
var options = {
    server: {
    auto_reconnect:true,
    }
};
mongoose.Promise = global.Promise;
mongoose.connect(config.mongoUrl, options);
db = mongoose.connection;// a global connection variable
// Event handlers for Mongoose
db.on('error', function (err) {
    console.log('Mongoose: Error: ' + err);
});
db.on('open', function() {
    console.log('Mongoose: Connection established');
});
db.on('disconnected', function() {
    console.log('Mongoose: Connection stopped, recconect');
    mongoose.connect(config.mongoUrl, options);
});
db.on('reconnected', function () {
    console.info('Mongoose reconnected!');
});
  var email,Recommendation;
  var today = new Date();
  var dd = today.getDate();
  var mm = today.getMonth()+1; //January is 0!
  var yyyy = today.getFullYear();
  if(dd<10) {
    dd='0'+dd
  } 
  if(mm<10) {
    mm='0'+mm
  } 
  var mytoday = dd+'/'+mm+'/'+yyyy;
  console.log(mytoday);
  myNoti.find({},function(err, docs){
    console.log('in the find function');
    for(var i=0; i<docs.length; i++)
    {
      email = docs[i].email;
      recommendation = docs[i].Recommendation;
      var tempDate = new Date(docs[i].dateNoti);
      dd = tempDate.getDate();
      mm = tempDate.getMonth()+1; //January is 0!
      yyyy = tempDate.getFullYear();
      if(dd<10) {
        dd='0'+dd
      } 
      if(mm<10) {
        mm='0'+mm
      } 
      tempDate = dd+'/'+mm+'/'+yyyy;
      if(mytoday === tempDate)
      {
        console.log("i'm in the if!");
        console.log("docs[i].repeat " +docs[i].repeat);
        today.setDate(today.getDate() + Number(docs[i].repeat));
        newupdate = new Date(today);
        myNoti.update({email: email,Recommendation: recommendation},{dateNoti: newupdate}, 
          function(err, num) {
            if(err)
              console.log(err);
            else
              console.log("updated"+num);
        }); 
        sendit(email, recommendation)
      }
    }
  });
}
function sendit(email, recommendation)
{
var transporter = nodemailer.createTransport({
    host: 'smtp.gmail.com',
    port: 465,
    secure: true, // use SSL
    auth: {
        user: '[e-mail]',
        pass: 'xxxxxx'
    }
});
// setup e-mail data
var mailOptions = {
    from: '"MY MEDICAL " <[e-mail]>', // sender address (who sends)
    to: email, // receiver
    subject: 'Notification', // Subject line
    text: '', // plaintext body
    html: recommendation
};
// send mail with defined transport object
transporter.sendMail(mailOptions, function(error, info){
    if(error){
        return console.log(error);
    }
    console.log('Message sent: ' + info.response);
});
}
sendMail();
}, null, true, 'America/Los_Angeles');

这段代码适用于我的本地主机，我的意思是当我只运行我的服务器(不运行此特定文件(时它可以工作 - 我将所有文件上传到 heroku，但这个 cron 不起作用，我收不到我的电子邮件......

我该怎么办？

Answer 1

1. 将函数放在公共 URL 中。

2. 在 Heroku 上添加临时调度程序附加组件以运行 cron 作业。(定期 API 调用(。

3. 将 Temporize 配置为调用您的 URL 以发送电子邮件以及每天要检查的次数，例如每天下午 1 点。

4. 如果要将其设为私有，请从 Temporize 生成登录令牌，并在函数中验证该令牌。
