在Node.js中发送电子邮件？

const nodemailer = require('nodemailer');

// 创建一个可重用的传输器对象
let transporter = nodemailer.createTransport({
  host: 'smtp.example.com',
  port: 587,
  secure: false, // true for 465, false for other ports
  auth: {
    user: 'your-email@example.com',
    pass: 'your-password'
  }
});

// 邮件选项
let mailOptions = {
  from: 'your-email@example.com',
  to: 'recipient@example.com',
  subject: 'Hello from Node.js',
  text: 'This is a test email sent from Node.js'
};

// 发送邮件
transporter.sendMail(mailOptions, (error, info) => {
  if (error) {
    console.log('Error occurred:', error.message);
    return;
  }
  console.log('Message sent successfully!');
  console.log('Message ID:', info.messageId);
});
