在node.js上发出http请求正常吗

const http = require('http');

const options = {
  hostname: 'example.com',
  port: 80,
  path: '/api/data',
  method: 'GET'
};

const req = http.request(options, (res) => {
  console.log(`STATUS: ${res.statusCode}`);
  console.log(`HEADERS: ${JSON.stringify(res.headers)}`);
  res.setEncoding('utf8');
  res.on('data', (chunk) => {
    console.log(`BODY: ${chunk}`);
  });
  res.on('end', () => {
    console.log('No more data in response.');
  });
});

req.on('error', (e) => {
  console.error(`problem with request: ${e.message}`);
});

req.end();

req.setTimeout(5000, () => {
  req.abort();
  console.error('Request timed out');
});

res.setHeader('Access-Control-Allow-Origin', '*');

req.on('error', (e) => {
  console.error(`Request error: ${e.message}`);
});
