在node.js中使用表单方法作为post的Ajax

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

const server = http.createServer((req, res) => {
  // 处理请求
});
const port = 3000;
server.listen(port, () => {
  console.log(`Server running at http://localhost:${port}/`);
});

const server = http.createServer((req, res) => {
  if (req.method === 'POST') {
    let body = '';
    req.on('data', (chunk) => {
      body += chunk;
    });
    req.on('end', () => {
      const postData = querystring.parse(body);
      // 处理POST请求的数据
    });
  }
});

const server = http.createServer((req, res) => {
  if (req.method === 'POST') {
    let body = '';
    req.on('data', (chunk) => {
      body += chunk;
    });
    req.on('end', () => {
      const postData = querystring.parse(body);
      // 处理POST请求的数据

      // 返回响应
      res.writeHead(200, { 'Content-Type': 'text/plain' });
      res.end('Post data received');
    });
  }
});
