如何在node.js中从表单中获取输入数据？

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 http = require('http');

const server = http.createServer((req, res) => {
  if (req.method === 'POST') {
    let data = '';
    req.on('data', chunk => {
      data += chunk;
    });
    req.on('end', () => {
      // 在这里处理表单数据
      console.log(data);
      res.end('Data received');
    });
  }
});

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

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

const server = http.createServer((req, res) => {
  if (req.method === 'POST') {
    let data = '';
    req.on('data', chunk => {
      data += chunk;
    });
    req.on('end', () => {
      const formData = querystring.parse(data);
      // 在这里处理表单数据
      console.log(formData);
      res.end('Data received');
    });
  }
});

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