如何从Node response对象获取请求URL？

const http = require('http');

const server = http.createServer((req, res) => {
  // 在这里处理请求
});

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

const server = http.createServer((req, res) => {
  const url = req.url;
  console.log('Request URL:', url);

  // 继续处理请求
});

const url = require('url');

const server = http.createServer((req, res) => {
  const parsedUrl = url.parse(req.url, true);
  console.log('Request URL:', parsedUrl);

  // 继续处理请求
});
