React路由器无法使用搜索字符串路由url

import React from 'react';
import { BrowserRouter as Router, Route, Link, useLocation, useSearchParams } from 'react-router-dom';

function App() {
  return (
    <Router>
      <div>
        <ul>
          <li>
            <Link to="/">Home</Link>
          </li>
          <li>
            <Link to="/about?param=value">About</Link>
          </li>
        </ul>

        <hr />

        <Route path="/" exact component={Home} />
        <Route path="/about" component={About} />
      </div>
    </Router>
  );
}

function Home() {
  return <h2>Home</h2>;
}

function About() {
  const [searchParams] = useSearchParams();
  const param = searchParams.get('param');

  return (
    <div>
      <h2>About</h2>
      <p>Parameter: {param}</p>
    </div>
  );
}

export default App;
