如何在express中创建带路由参数和查询参数的api

$ mkdir myapp
$ cd myapp
$ npm init -y
$ npm install express --save

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

app.get('/api/users/:id', (req, res) => {
  const userId = req.params.id;
  const queryParam = req.query.param;
  
  // 处理路由参数和查询参数的逻辑
  // ...
  
  res.send('API response');
});

const port = 3000;

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

$ node app.js
