Node js http server接受POST和JSON

const http = require('http');

const server = http.createServer((req, res) => {
  if (req.method === 'POST' && req.headers['content-type'] === 'application/json') {
    let body = '';
    req.on('data', (chunk) => {
      body += chunk;
    });
    req.on('end', () => {
      try {
        const data = JSON.parse(body);
        // 在这里处理接收到的JSON数据
        // ...
        res.statusCode = 200;
        res.setHeader('Content-Type', 'application/json');
        res.end(JSON.stringify({ message: 'Data received successfully' }));
      } catch (error) {
        res.statusCode = 400;
        res.end();
      }
    });
  } else {
    res.statusCode = 404;
    res.end();
  }
});

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