Laravel 5 Middleware Doesn't work - laravel

Question

I have problem with my custom middleware. It doesn't work. I have registered it in Kernel.php, only in $routeMiddleware. Here is my code:
/**
* The application's route middleware.
*
* #var array
*/
protected $routeMiddleware = [
'auth' => \App\Http\Middleware\Authenticate::class,
'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
'test' => \App\Http\Middleware\TestMiddleware::class
];
}
Here is my Controller Code:
/**
* Middleware Activated
*/
public function __constructor()
{
$this->middleware('test');
}
and here is my custom middleware code:
protected $auth;
/**
* Handle an incoming request.
*
* #param \Illuminate\Http\Request $request
* #param \Closure $next
* #return mixed
*/
public function handle($request, Closure $next)
{
if (!$this->auth->check())
{
return redirect('/');
}
return $next($request);
}
When I'm logout and type in url
profile/21
it shows me the profile of user with id 21. I want to prevent that with middleware but it won't work for me.
Does anyone have an idea how to do that or where is the mistake?

Answer 1

To make sure if the middleware gets triggered put something like die('middleware triggerd'); inside the handle function of the middleware.
I noticed you have function __constructor() instead of function __construct().
That might be the problem.
If it does trigger the middleware but you still have the same problem try replacing:
if (!$this->auth->check()) with if (!\Auth::check())
