如何在没有Express的情况下从表单域获取数据？

const http = require('http');

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

const port = 3000; // 指定监听的端口号
server.listen(port, () => {
  console.log(`Server running on port ${port}`);
});

const http = require('http');
const querystring = require('querystring');

const server = http.createServer((req, res) => {
  if (req.method === 'POST' && req.url === '/submit') {
    let body = '';
    
    req.on('data', (chunk) => {
      body += chunk;
    });

    req.on('end', () => {
      const formData = querystring.parse(body);
      // 在这里处理获取到的表单数据
      console.log(formData);
      res.end('Data received');
    });
  } else {
    res.end('Invalid request');
  }
});

const port = 3000; // 指定监听的端口号
server.listen(port, () => {
  console.log(`Server running on port ${port}`);
});
