生成授权域名

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

app.get('/generate-token', (req, res) => {
  const token = generateToken(); // 自定义生成token的逻辑
  const authorizedDomain = `https://${token}.example.com`;
  res.send(authorizedDomain);
});

function generateToken() {
  // 生成token的逻辑，可以使用UUID、随机字符串等
  return 'randomToken123';
}

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

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

app.use((req, res, next) => {
  const authorizedDomain = 'https://randomToken123.example.com'; // 预先定义的授权域名
  if (req.headers.host === authorizedDomain) {
    next(); // 验证通过，继续处理请求
  } else {
    res.status(403).send('Forbidden'); // 验证失败，返回403错误
  }
});

app.get('/protected-resource', (req, res) => {
  res.send('This is a protected resource');
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});
