如何在RestRserve中从路径中提取参数？

const RestRserve = require('restrserve');

const app = new RestRserve();

app.get('/users/{id}', (req, res) => {
  const url = req.url;
  const regex = /\/users\/(\w+)/; // 正则表达式匹配/users/后的参数值
  const match = url.match(regex);
  const id = match[1]; // 提取参数值

  // 执行相应的逻辑，使用提取的参数值

  res.send(`User ID: ${id}`);
});

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