Laravel - Controllers - Controller Middleware

Middleware may be assigned to the controller's routes in your route files:

    Route::get('profile', [UserController::class, 'show'])->middleware('auth');

Or, you may find it convenient to specify middleware within your controller's constructor. Using the middleware method within your controller's constructor, you can assign middleware to the controller's actions:

    class UserController extends Controller
         * Instantiate a new controller instance.
         * @return void
        public function __construct()

Controllers also allow you to register middleware using a closure. This provides a convenient way to define an inline middleware for a single controller without defining an entire middleware class:

    $this->middleware(function ($request, $next) {
        return $next($request);
