Question

首先，让我更具体一点。我在我的网站上有一个联系页面的nodemailer代码设置，它工作得很好。但是，我有另一个页面，服务，我有另一个表单，并希望使用此页面的以前的设置代码，所以我能够将提交的信息作为电子邮件发送。我尝试制作另一个文件并粘贴相同的代码，但将变量命名为app2，transporter2等等。但它不会起作用。我是nodejs开发的初学者，所以我需要帮助。实现这一目标的最佳方法是什么？

顺便说一下;联系人，服务页面和app.js（nodejs代码）文件位于根文件夹中。

节点js：

const express = require('express');
const bodyParser = require('body-parser');
const exphbs = require('express-handlebars');
const path = require('path');
const nodemailer = require('nodemailer');

const app = express();

// View engine setup
app.engine('handlebars', exphbs());
app.set('view engine', 'handlebars');

// Static folder
app.use('/public', express.static(path.join(__dirname, 'public')));
app.use('/', express.static(path.join(__dirname, '')));

// Body Parser Middleware
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());

app.get('/', (req, res) => {
  res.render('contact');
});

app.post('/send', (req, res) => {
  const output = `
    <ul>  
      <li>Name: ${req.body.name}</li>
      <li>Email: ${req.body.email}</li>
      <li>Phone: ${req.body.phone}</li>
    </ul>
  `;

  // create reusable transporter object using the default SMTP transport
  let transporter = nodemailer.createTransport({
    service: 'gmail',
    port: 25,
    secure: false, // true for 465, false for other ports
    auth: {
        user: 'email', // senders email
        pass: 'password' // senders password
    },
    tls:{
      rejectUnauthorized:false
    }
  });

  // setup email data with raw html
  let mailOptions = {
      from: '"xyz" <xyz@info.com>', // sender address
      to: req.body.email, // receiver or receivers
      subject: 'xyz', // Subject line
      html: output // html body
  };

  // send mail with defined transport object
  transporter.sendMail(mailOptions, (error, info) => {
      if (error) {
          return console.log(error);
      }
      console.log('Message sent: %s', info.messageId);   
      console.log('Preview URL: %s', nodemailer.getTestMessageUrl(info));

      res.render('contact', {msg:'Your contact message has successfully sent to us.'});
  });
  });

app.listen(3000, () => console.log('Server started...'));

为什么，你创建一个模块。 https://nodejs.org/api/modules.html

this.clock = Observable.interval(1000).map(()=> new Date(1512151753372));

{{clock | async | date:'medium'}}

然后将其包含在您需要的任何位置：

//yourModule.js
const sendMail = (email, output) => new Promise((resolve, reject) => {
  //your code to send mail.
  //resolve the promise
})

module.exports { sendMail }

如何在第二种情况下使用节点js代码块？
