如何使用React路由配置实现受保护的路由

npm install react-router-dom

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

const ProtectedRoute = ({ component: Component, isAuthenticated, ...rest }) => (
  <Route
    {...rest}
    render={props =>
      isAuthenticated ? (
        <Component {...props} />
      ) : (
        <Redirect to="/login" />
      )
    }
  />
);

const App = () => {
  const isAuthenticated = // 根据你的认证逻辑确定用户是否已登录
  return (
    <Router>
      <Switch>
        <Route exact path="/login" component={Login} />
        <ProtectedRoute
          path="/protected"
          component={ProtectedComponent}
          isAuthenticated={isAuthenticated}
        />
        <Route path="/" component={Home} />
      </Switch>
    </Router>
  );
};

const ProtectedComponent = () => (
  <div>
    <h1>Protected Component</h1>
    {/* 受保护的组件内容 */}
  </div>
);

const Home = () => (
  <div>
    <h1>Home</h1>
    {/* 主页内容 */}
  </div>
);

const Login = () => (
  <div>
    <h1>Login</h1>
    {/* 登录页面内容 */}
  </div>
);
