# Request

Wolff\Core\Http\Request

Wolff offers you a quite useful and complete request object. It implements the Wolff\Core\Http\RequestInterface interface.

This can be done to avoid the superglobals of PHP, giving you a more object oriented syntax.

This request object is the one that must be passed as parameter to the Controller's public functions, route functions, and middleware functions.

Route:

Route::get('/', function($request) {
});

Route::code(404, function($request) {
});

Middleware:

Middleware::before('/', function($request) {
});

Controller:

namespace Controller;

class Home extends Controller
{
    public function index($request)
    {
    }
}
