如何启动NodeJS post？

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

const server = http.createServer((req, res) => {
  // 服务器逻辑
});

server.listen(8080, () => {
  console.log('Server is running on port 8080');
});

const server = http.createServer((req, res) => {
  const reqUrl = url.parse(req.url, true);
  const reqMethod = req.method;
  
  // 处理POST请求
  if (reqMethod === 'POST') {
    // POST请求逻辑
  }
});

const server = http.createServer((req, res) => {
  const reqUrl = url.parse(req.url, true);
  const reqMethod = req.method;
  
  // 处理POST请求
  if (reqMethod === 'POST') {
    let data = '';
    
    req.on('data', chunk => {
      data += chunk;
    });
    
    req.on('end', () => {
      // 解析POST请求数据
      const postData = querystring.parse(data);
      
      // 处理POST请求逻辑
    });
  }
});
