Laravel 5.3 session in constructor

n Laravel 5.3, you can't access the session or authenticated user in your controller's constructor because the middleware has not run yet. As an alternative, you may define a Closure based middleware directly in your controller's constructor

public function __construct()
    {
    $this->middleware(function ($request, $next) {
               $this->cart = session()->has( 'cart' ) ? session()->get( 'cart.items' ) : [];

                return $next($request);
        });
}

I already did that, but i need it in my Cart class not in controller.

@ABDELRHMAN ,you are right, As an alternative, you may define a Closure based middleware directly in your controller's constructor. Before using this feature, make sure that your application is running Laravel 5.3.4 or above, pay attention to this.

and you can see this: https://github.com/laravel/framework/issues/15072

@XiaodongHe , yes , but he want to do that in a class not controller , it should work with no thing , but it's not working with him
