反应 PrivateRoute 授权路线

Question

I am working on a basic react auth app, right now the routes /signup and /login work when I run this repo with my .env.local file that contains firebase auth variables. https://github.com/MartinBarker/react-auth-app

I am trying to make it so that the '/' route that points to Dashboard will only be accessible for a user who is currently signed in, and if a user is not signed in but tries to access the '/' route they will be redirected to the '/login' page.

But whenever I use the route

<PrivateRoute exact path="/" element={Dashboard} /> 

my chrome devtools console shows a blank page with error messages:

index.tsx:24 Uncaught Error: [PrivateRoute] is not a <Route> component. All component children of <Routes> must be a <Route> or <React.Fragment>

my PrivateRoute.js looks like this:

// This is used to determine if a user is authenticated and
// if they are allowed to visit the page they navigated to.

// If they are: they proceed to the page
// If not: they are redirected to the login page.
import React from 'react'
import { Navigate, Route } from 'react-router-dom'
import { useAuth } from '../Contexts/AuthContext'

const PrivateRoute = ({ component: Component, ...rest }) => {

  // Add your own authentication on the below line.
  //const isLoggedIn = AuthService.isLoggedIn()

  const { currentUser } = useAuth()
  console.log('PrivateRoute currentUser = ', currentUser)

  return (
    <Route
      {...rest}
      render={props =>
        currentUser ? (
          <Component {...props} />
        ) : (
          //redirect to /login if user is not signed in
          <Navigate to={{ pathname: '/login'}} />
        )
      }
    />
  )
}

export default PrivateRoute

Im not sure why this error is occurring, any help is appreciated

This behaviour seems to have changed in ReactRouter V6 here is the solution we came up with for a project.

Private route *Re-creating the users question code

import React from 'react'
import { Navigate, Route } from 'react-router-dom'
import { useAuth } from '../Contexts/AuthContext'

const PrivateRoute = ({ children }) => {

  // Add your own authentication on the below line.
  //const isLoggedIn = AuthService.isLoggedIn()

  const { currentUser } = useAuth()
  console.log('PrivateRoute currentUser = ', currentUser)

  return (
    <>
      {
      currentUser ? (
          children
        ) : (
          //redirect to /login if user is not signed in
          <Navigate to={{ pathname: '/login'}} />
        )
      }
    </>
  )
}

export default PrivateRoute

Typescript *Our actual code implementation of this issue

const PrivateRoute: React.FC = ({ children }) => {
  const navigate = useNavigate();
  const { isAuthenticated, isAuthLoading } = useAuth();
  const { user, isLoadingUser } = useContext(UserContext);

  // Handle users which are not authenticated
  // For example redirect users to different page

  // Show loader if token is still being retrieved
  if (isAuthLoading || isLoadingUser) {
    // TODO: show full page loader
    return (
      <div>Loading...</div>
    );
  }

  // Proceed with render if user is authenticated
  return (
    <>
      {children}
    </>
  );
};

Router

<Router>
  <Routes>
    <Route
      path={routes.user.accountSignup.path}
      element={
        <PrivateRoute>
          <AccountSignup />
        </PrivateRoute>
      }
    />
  </Routes>
</Router>
