如何使用HTTP Get请求来仅获取Array中对象中的特定属性？

const express = require('express');
const app = express();

const users = [
  { name: 'Alice', age: 25, email: 'alice@example.com' },
  { name: 'Bob', age: 30, email: 'bob@example.com' },
  { name: 'Charlie', age: 35, email: 'charlie@example.com' }
];

app.get('/users', (req, res) => {
  const fields = req.query.fields; // 获取查询参数fields的值

  if (fields) {
    const filteredUsers = users.map(user => {
      const filteredUser = {};
      fields.split(',').forEach(field => {
        if (user.hasOwnProperty(field)) {
          filteredUser[field] = user[field];
        }
      });
      return filteredUser;
    });

    res.json(filteredUsers);
  } else {
    res.json(users);
  }
});

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

[
  { "name": "Alice" },
  { "name": "Bob" },
  { "name": "Charlie" }
]
