Laravel add custom middleware to route group - laravel

Question

in my web application i have admin panel and i'm trying to make access to users that they have admin role by this code:
namespace App\Http\Middleware;
use Closure;
class CheckUserAdminRole
{
public function handle($request, Closure $next)
{
if (auth()->check()) {
if (auth()->check() && !auth()->user()->hasRole('admin')) {
auth()->logout();
return redirect(route('system.messages','userIsNotAdmin'));
}
}
return $next($request);
}
}
and in my routs i have this route group:
Route::group(['namespace' => 'Dashboard', 'middleware' => ['auth:web'], 'prefix' => 'dashboard'], function () {
$this->group(['prefix' => 'administrator'], function () {
$this->get('panel', 'AdminController#index');
});
my kernel:
protected $middleware = [
\Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
\Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,
...
\App\Http\Middleware\CheckUserAdminRole::class,
];
now when i add my middleware as CheckUserAdminRole to route group like with this code:
Route::group(['namespace' => 'Dashboard', 'middleware' => ['auth:web','CheckUserAdminRole'], 'prefix' => 'dashboard'], function () {
i get this error:
Class CheckUserAdminRole does not exist
this codes couldn't resolve my problem:
php artisan route:clear
php artisan cache:clear
php artisan config:clear
composer dump-autoload

Answer 1

Instead of registering your middleware in the $middleware array, you should register it in $routeMiddleware like so:
protected $routeMiddleware = [
...
'checkAdmin' => \App\Http\Middleware\CheckUserAdminRole::class,
];
Note: registering a middlware in the $middleware array results in it being executed for every request and therefore is not applicable on specific routes.
Then you can use it in your routes with the checkAdmin name:
Route::group(['namespace' => 'Dashboard', 'middleware' => ['auth:web','checkAdmin'], 'prefix' => 'dashboard'], function () {

You can also use middleware and route group together easily like so:
Route::group(['prefix' => 'admin', 'middleware' => 'auth'], function()
{
//All the routes that belongs to the group goes here
Route::get('dashboard', function() {} );
});

Answer 3

Here's a simple fix without touching the Kernel file and taking advantage of the Policy. The accessAdmin is a function created inside Policy file.
Route::group(['namespace' => 'Dashboard', 'middleware' => 'can:accessAdmin, App\User', 'prefix' => 'dashboard'], function () {
$this->group(['prefix' => 'administrator'], function () {
$this->get('panel', 'AdminController#index');
});

Answer 4

You can try middleware with prefix and groups.
Route::middleware(['Auth'])->prefix('api/')->group(function() {
Route::group(['prefix' => 'review/'], function () {
Route::get('/', 'User\Controllers\Api\UserController#getUserReviews');
});
});
Hope its helps
