javascript - 错误 : [PrivateRoute] is not a component. 的所有子组件必须是 或

Question

我正在使用 React Router v6 并为我的应用程序创建私有(private)路由。
在文件 PrivateRoute.js 中，我有代码

import React from 'react';
import {Route,Navigate} from "react-router-dom";
import {isauth}  from 'auth'

function PrivateRoute({ element, path }) {
  const authed = isauth() // isauth() returns true or false based on localStorage
  const ele = authed === true ? element : <Navigate to="/Home"  />;
  return <Route path={path} element={ele} />;
}

export default PrivateRoute

在文件 route.js 我写成:

 ...
<PrivateRoute exact path="/" element={<Dashboard/>}/>
<Route exact path="/home" element={<Home/>}/>

我经历过相同的例子 React-router Auth Example - StackBlitz, file App.tsx
有什么我想念的吗？

我今天遇到了同样的问题，并根据这个 very helpful article 提出了以下解决方案由 Andrew Luca
在 PrivateRoute.js 中:

import React from 'react';
import { Navigate, Outlet } from 'react-router-dom';

const PrivateRoute = () => {
    const auth = null; // determine if authorized, from context or however you're doing it

    // If authorized, return an outlet that will render child elements
    // If not, return element that will navigate to login page
    return auth ? <Outlet /> : <Navigate to="/login" />;
}

在 App.js 中(我在其他一些页面中留下了示例):

import './App.css';
import React, {Fragment} from 'react';
import {BrowserRouter as Router, Route, Routes} from 'react-router-dom';
import Navbar from './components/layout/Navbar';
import Home from './components/pages/Home';
import Register from './components/auth/Register'
import Login from './components/auth/Login';
import PrivateRoute from './components/routing/PrivateRoute';

const App = () => {
  return (
    <Router>
      <Fragment>
        <Navbar/>
        <Routes>
          <Route exact path='/' element={<PrivateRoute/>}>
            <Route exact path='/' element={<Home/>}/>
          </Route>
          <Route exact path='/register' element={<Register/>}/>
          <Route exact path='/login' element={<Login/>}/>
        </Routes>
      </Fragment>
    </Router>
    
  );
}

在上面的路由中，这是私有(private)路由:

<Route exact path='/' element={<PrivateRoute/>}>
      <Route exact path='/' element={<Home/>}/>
</Route>

如果授权成功，将显示该元素。否则，它将导航到登录页面。
