nodejs中不能通过post方法插入数据吗？

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

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);
      // 将postData插入数据库的逻辑代码
      res.end('Data inserted successfully');
    });
  } else {
    res.end('Invalid request method');
  }
});

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