使用服务器自动发送通知电子邮件

Question

我需要在 linux 服务器上做一个通知发送者。这个想法是这个发件人每周在 JQL 中进行一次查询，如果它返回某些内容，则将电子邮件发送到某个列表。 我对服务器和 JavaScript 比较陌生。我已经在做 JQL 查询了，但是：

1. 我需要发件人知道执行此操作的正确时间。触发 Sender 的最有效方式是什么？
2. 如何在 JS 中将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。我也很感激任何关于阅读材料的建议。谢谢。

您可以将 NODEJS 与 sendgrid api 一起用于您的服务器端和电子邮件 api。实际的客户端，您可以将其连接到网站上，或者只是运行 nodejs 应用程序。 所以开始的地方是https://nodejs.org/ 和http://sendgrid.com 那肯定会满足您的电子邮件需求。这是我使用的一个函数，去掉了我的 api 密钥（显然），对 postEmail 的调用实际上发送了邮件，剩下的就是验证。 发送电子邮件非常容易。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

      function getEmail(){
          var requestBody = finished;
          var requestPost = JSON.parse(JSON.stringify(emptyRequest));
          requestPost.method = 'GET';

          sg.API(requestPost, function (error, response) {
            console.log(response.statusCode + ' SUCCESSFUL EMAIL');
             console.log('MESSAGE ID = '+ response.headers['x-message-id']) ;
                        })//end internal api function
            }//end api
