Laravel 5 Login Function change argument

I override the function login in LoginController. by default she was in the Trait: Illuminate\Foundation\Auth\AuthenticatesUsers;

This function in LoginController in Laravel must take param of type \Illuminate\Http\Request.

if i change this param on my custom request error when submitting form 403|Forbidden

Request created with composer:

php artisan make:request StoreBlogPost

Can I do something here?
