Question

我正在研究spatie laravel我想将未经授权的用户重定向到该视图上的特定视图它将有一个简单的按钮重定向到后面我试过这样但是它给我的错误像

Symfony \ Component \ Debug \ Exception \ FatalThrowableError (E_ERROR)
Call to a member function setCookie() on null

这是app / exception / handler.php中的代码

 public function render($request, Exception $exception)
{

     if ($exception instanceof \Spatie\Permission\Exceptions\UnauthorizedException) {
    // Code here ...
      return view('404');
}
    return parent::render($request, $exception);
}
 /**
 * Convert an authentication exception into an unauthenticated response.
 *
 * @param  \Illuminate\Http\Request  $request
 * @param  \Illuminate\Auth\AuthenticationException  $exception
 * @return \Illuminate\Http\Response
 */
protected function unauthenticated($request, AuthenticationException $exception)
{
    if ($request->expectsJson()) {
        return response()->json(['error' => 'Unauthenticated.'], 401);
    }
    $guard = array_get($exception->guards(), 0);
    switch ($guard) {
      case 'admin':
        $login = 'admin.login';
        break;
      default:
        $login = 'login';
        break;
    }
    return redirect()->guest(route($login));
}

在404.blade.php

 @extends('web.layouts.default')
@section('title', '404')
@section('content')
<div class="container">
    <div class="row justify-content-center">
        <div class="col-md-8">
            <div class="card">
                <div class="card-header">You are not authorized</div>

                <div class="card-body">

                    <a href="{{ back() }}" class="btn btn-primary"> Click here to go back</a>
                 </div> <br>    <br>

        </div>
    </div>
</div>
@endsection

我有gievn查看主页权限给用户，当有这个权限你可以查看profileController中的个人资料页面我写的像

 <?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Auth;
use Spatie\Permission\Models\Permission;
class ProfileController extends Controller
{
     public function __construct()
    {
        //$this->middleware('auth',['except' => 'otp']);
       // return redirect(route('logout'));
         $this->middleware(['permission:view homepage','auth']);
    }

    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {

        //$per=Auth::user()->getAllPermissions();
        return view('profile');

    }
}

当我输入/配置文件给没有查看主页权限的用户时我得到上述错误

请告诉我你想要的任何意见

您应该尝试在 404.blade.php 文件中使用以下按钮，并且它可以正常工作。

<a href="{{ redirect()->back()->getTargetUrl() }}" class="btn btn-primary"> Click here to go back</a>
