Laravel 5.2-使用Auth:：check（）在中间件中不起作用

Question

我正在尝试在我的Laravel 5.2应用程序中为不同类型的用户制作一个中间件。所以，我正在做的是为不同的用户制作不同的中间件。

据我所知，如果不考虑中间件web，Auth:：check（）将无法工作。

所以，我所做的是-

routes.php

Route::group(['middleware' => ['web','admin']], function ()
{
    //suspend, activate, delete
    Route::get('users', [
        'uses'          => 'AdminController@users',
        'as'            => 'users'
    ]);

    //Edit,activate,suspend, delete
    Route::get('articles', [
        'uses'          => 'AdminController@articles',
        'as'            => 'articles'
    ]);
});

管理iddleware.php

<?php

namespace App\Http\Middleware;

use Closure;
use Auth;

class AdminMiddleware
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if (Auth::check())
        {
            return "asd";
            //return Auth::user();
            //return redirect('home');
        }
        else
        {
            return redirect('login');
        }

        //now return the valid request
        return $next($request);
    }
}

Kernel.php

protected $routeMiddleware = [
    'auth'          => \App\Http\Middleware\Authenticate::class,
    'admin'         => \App\Http\Middleware\AdminMiddleware::class,
    'user'          => \App\Http\Middleware\UserMiddleware::class,
    'auth.basic'    => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
    'guest'         => \App\Http\Middleware\RedirectIfAuthenticated::class,
    'throttle'      => \Illuminate\Routing\Middleware\ThrottleRequests::class,
];

AdminController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;
use App\Http\Controllers\Controller;

class AdminController extends Controller
{
    public function users()
    {
        return view('admin.users');
    }

    public function articles()
    {
        return view('admin.articles');
    }
}

但我得到了这个错误-

在中间件内部调用“return Auth:：user（）；”时，“return Auth:：user（）；”在其他位置（视图和控制器）工作，但与旧版本的Laravel不同。

有谁能帮忙吗？

您也在web组中添加了路由，所以请确保您的内核文件应该包含以下中间件组。

/**
 * The application's route middleware groups.
 *
 * @var array
 */
protected $middlewareGroups = [
    'web' => [
        \App\Http\Middleware\EncryptCookies::class,
        \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
        \Illuminate\Session\Middleware\StartSession::class,
        \Illuminate\View\Middleware\ShareErrorsFromSession::class,
        \App\Http\Middleware\VerifyCsrfToken::class,
    ],

    'api' => [
        'throttle:60,1',
    ],
];

由于会话而导致的错误。确保内核文件包含会话中间件。

嗨@Cowboy和@lagbox，谢谢你的帮助，不幸的是他们不工作，但我已经解决了。

我通过跑步解决了这个问题-

php artisan缓存：清除

作曲家转储-自动加载

php artisan clear已编译

php artisan优化

然后中间件-

<?php

namespace App\Http\Middleware;

use Closure;
use Auth;

class AdminMiddleware
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if (Auth::check())
        {
            if(strcmp( "admin" , Auth::user()->user_type ) != 0 )
                return redirect('home');
            else
                return $next($request);
        }
        else
        {
            return redirect('login');
        }

        //now return the valid request
        //return $next($request);
    }
}

路线-

Route::group(['middleware' => ['web','admin']], function ()
{
    //suspend, activate, delete
    Route::get('users', [
        'uses'          => 'AdminController@users',
        'as'            => 'users'
    ]);

    //Edit,activate,suspend, delete
    Route::get('articles', [
        'uses'          => 'AdminController@articles',
        'as'            => 'articles'
    ]);
});

你可以这样做，根据需要进行调整

public function handle($request, Closure $next)
{
    $user = $request->user();

    if (! $user || $user->user_type != 'admin') {
        return redirect('login');
    }

    return $next($request);
}

您收到的错误来自于您没有从中间件返回响应对象的事实。VerifyCsrfToken中间件试图将cookie添加到它通过将请求向下传递到管道而获得的响应中。在这种情况下，它不是获取响应对象，而是获取字符串或User，因为在中间件中返回了字符串或User。
