如何在没有关系嵌套对象的情况下创建post和get web服务

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

app.use(express.json());

app.post('/api/data', (req, res) => {
  const data = req.body; // 获取POST请求中的数据
  // 处理数据逻辑
  // ...
  res.send('Data received successfully');
});

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

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

app.get('/api/data', (req, res) => {
  // 获取GET请求中的参数
  const param1 = req.query.param1;
  const param2 = req.query.param2;
  
  // 处理数据逻辑
  // ...
  
  const responseData = {
    // 构造返回的数据
    // ...
  };
  
  res.json(responseData);
});

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