域名到期没续费会怎样

const express = require('express');
const nodemailer = require('nodemailer');

const app = express();
const domain = 'example.com';
const expirationDate = new Date('2024-12-31'); // 假设域名到期时间为2024-12-31

app.get('/check-domain', (req, res) => {
  const now = new Date();
  if (now > expirationDate) {
    res.send('域名已过期，请及时续费！');
  } else {
    const daysLeft = Math.ceil((expirationDate - now) / (1000 * 60 * 60 * 24));
    res.send(`域名到期时间：${expirationDate.toDateString()}，还有${daysLeft}天，请及时续费！`);
  }
});

app.listen(3000, () => {
  console.log('服务器运行在 http://localhost:3000');
});

// 设置定时任务，每天检查一次域名到期时间
setInterval(() => {
  const now = new Date();
  if (now > expirationDate) {
    sendReminderEmail();
  }
}, 86400000); // 每天检查一次

function sendReminderEmail() {
  const transporter = nodemailer.createTransport({
    service: 'gmail',
    auth: {
      user: 'your-email@gmail.com',
      pass: 'your-email-password'
    }
  });

  const mailOptions = {
    from: 'your-email@gmail.com',
    to: 'admin@example.com',
    subject: '域名到期提醒',
    text: `域名 ${domain} 已过期，请及时续费！`
  };

  transporter.sendMail(mailOptions, (error, info) => {
    if (error) {
      console.log(error);
    } else {
      console.log('邮件发送成功：' + info.response);
    }
  });
}
