Request and data from routes in Laravel?

Question

Laravel

The essence of the question is this: how to check in intermediaries (middleware) the data that is transmitted using routes?
For example, there is a route:

Route::get('somedata/{id}', ['middleware' =>'check.somedata', 'uses' => '[email protected]']);

How to pull out in the intermediary idto check its existence, etc.? There are suspicions that using Request, but there is nothing like that in the documentation?

Answer 1

class MyMiddleware implements Middleware
{
    public function handle($request, Closure $next)
    {
        $id = $request->route('id');
        //stuff...
        $next($request);
    }
}

And yet, the method $request->route()->parameters();can get all the parameters.
