无法在node.js获取angularjs http请求消息数据

const http = require('http');

const server = http.createServer((req, res) => {
  let requestData = '';

  req.on('data', (chunk) => {
    requestData += chunk;
  });

  req.on('end', () => {
    // 在这里可以对requestData进行处理
    console.log(requestData);

    res.statusCode = 200;
    res.setHeader('Content-Type', 'text/plain');
    res.end('Data received');
  });
});

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