自动发送带服务器的通知电子邮件

Question

我需要在Linux服务器上进行通知发送者。这个想法是每周一次，此发件人在JQL中进行查询，如果返回某些内容，则将电子邮件发送到某个列表。我是服务器和JavaScript的新手。我已经在做JQL查询，但是：

1. 我需要发件人知道正确的时间。触发发件人的最有效方法是什么？
2. 如何将JS中的电子邮件从特定地址发送到电子邮件列表？

粗略的草图：

//magic, part 1
WaitUntilMonday();
var result = DoJQLQuery();
if (result != '')
  SendNotificationEmail(from,to,message);
  
//magic, part 2

我试图搜索它，但我不知道从哪里开始。我也感谢您也建议阅读材料。谢谢。

Answer 1

嗯，您可以将NODEJS与SendGrid API一起使用用于服务器端和电子邮件API。实际客户端，您可以将其连接到网站上的一个，也可以只是运行Nodejs应用程序。因此，起点是https://nodejs.org/和http://sendgrid.com那肯定会满足您的电子邮件需求。这是我使用的API密钥剥离的功能（显然），后邮件的呼叫实际发送了邮件，其余的就是验证。发送电子邮件非常简单。祝你好运。

const SENDGRID_API_KEY = "SG.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
var helper = require('sendgrid').mail;
var sg = require('sendgrid')(SENDGRID_API_KEY);
var emptyRequest = require('sendgrid-rest').request;
var request = require("request");
    function makeEmail(whereFrom, whereTo, mysubject, mycontent){
      from_email = new helper.Email(whereFrom);
      to_email = new helper.Email(whereTo);
      subject = mysubject;
      content = new helper.Content("text/html", mycontent);
      mail = new helper.Mail(from_email, subject, to_email, content);
      custom_arg = new helper.CustomArgs("OURGUID", "ourcustomarg");
      mail.addCustomArg(custom_arg);
      var finished = mail.toJSON();

      var timer = 0;
      function postEmail(){
          var requestBody = finished;
          var requestPost = JSON.parse(JSON.stringify(emptyRequest));
          requestPost.method = 'POST';
          requestPost.path = '/v3/mail/send';
          requestPost.body = requestBody;
          sg.API(requestPost, function (error, response) {
            console.log(response.statusCode + ' STATUS')
             console.log('MESSAGE ID = '+ response.headers['x-message-id']) 
            if(response.statusCode == '202') {
              console.log(response.statusCode + ' EMAIL SENT TO SENDGRID AND QUED')
                          }//response if statement
          if(response.statusCode != '202'){
            console.log(response.statusCode + ' Something went wrong')}
                          })//end internal api function
            }//end api
    postEmail(finished);//actually sending the mail
