How do I pass my own parameters to Middleware in Ravel 5.0?

Ravel 5.1 introduces a new Middleware Parameters feature that allows you to pass your own parameters to Middleware, but due to PHP version requirements, you are forced to use Ravel 5.0.

I am trying to create Middleware this time and check if the logged in user has the permissions specified.
Specifically, I'm going to check it in the form of Auth::user()->hasRole('owner'), so I'm worried about how to tell middleware the parameters to pass to hasRole().

First of all, I borrow Request::route() and pass the parameters, but I can't predict what kind of problems will happen because it's not an officially prepared method.

The middleware is specified in __construct() on each controller.

public function__construct()
{
    $this->middleware('auth');
    Request::route()->setParameter('allowed_roles', ['owner']);
    $this->middleware('role');
}

The middleware contains the following:

class CheckRole
{
    public function handle($request,Closure$next)
    {
        $roles = $request->route()->parameter('allowed_roles', array());

        if(empty($roles)||$request->user()->hasRole($roles))
        {
            return$next($request);
        } else{
            return response('Unauthorized.',401);
        }
    }

}

In such a case, how is it standard to pass the parameters?
"Also, is ""Request::route()->setParameter()" good to use for these personal purposes?"
Thank you for your cooperation.
