NodeJS Json是否仅返回id？

const http = require('http');

const server = http.createServer((req, res) => {
  if (req.url === '/user') {
    // 返回一个包含用户信息的对象
    res.writeHead(200, {'Content-Type': 'application/json'});
    res.end(JSON.stringify({id: 1, name: 'John Doe', email: 'john@example.com'}));
  } else if (req.url === '/users') {
    // 返回一个包含多个用户的数组
    res.writeHead(200, {'Content-Type': 'application/json'});
    res.end(JSON.stringify([
      {id: 1, name: 'John Doe', email: 'john@example.com'},
      {id: 2, name: 'Jane Smith', email: 'jane@example.com'}
    ]));
  } else {
    // 返回一个单一值
    res.writeHead(200, {'Content-Type': 'application/json'});
    res.end(JSON.stringify({status: 'success'}));
  }
});

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