如何使用ajax和nodemailer来发送邮件？

npm install nodemailer

$.ajax({
  url: '/send-email',
  type: 'POST',
  data: {
    to: 'recipient@example.com',
    subject: '邮件主题',
    text: '邮件内容'
  },
  success: function(response) {
    console.log('邮件发送成功');
  },
  error: function(error) {
    console.log('邮件发送失败');
  }
});

const nodemailer = require('nodemailer');

app.post('/send-email', (req, res) => {
  const { to, subject, text } = req.body;

  // 创建一个SMTP传输对象
  let transporter = nodemailer.createTransport({
    service: '腾讯企业邮',
    auth: {
      user: 'your-email@example.com',
      pass: 'your-password'
    }
  });

  // 邮件选项
  let mailOptions = {
    from: 'your-email@example.com',
    to: to,
    subject: subject,
    text: text
  };

  // 发送邮件
  transporter.sendMail(mailOptions, (error, info) => {
    if (error) {
      console.log('邮件发送失败:', error);
      res.status(500).send('邮件发送失败');
    } else {
      console.log('邮件发送成功:', info.response);
      res.status(200).send('邮件发送成功');
    }
  });
});
