如何点击一次并导航到请求页面？

npm install react-router-dom

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

// 定义两个页面组件
const HomePage = () => <h1>Home Page</h1>;
const RequestPage = () => <h1>Request Page</h1>;

function App() {
  return (
    <Router>
      <div>
        <nav>
          <ul>
            <li>
              <Link to="/">Home</Link>
            </li>
            <li>
              <Link to="/request">Request</Link>
            </li>
          </ul>
        </nav>

        <Switch>
          <Route path="/" exact component={HomePage} />
          <Route path="/request" component={RequestPage} />
        </Switch>
      </div>
    </Router>
  );
}

export default App;
