Warning: Missing argument 1 when passing parameters from url to controller (laravel)

I am creating this site and I want to pass URL parameters to routes and routes to the controller, I searched for documents and Google, but I can not find a solution to my problem.

This is an example url

locations/search?q=parameter1

My route right now is as follows:

Route::group(array('prefix'=>'search'),function()
{
    Route::get('locations/{src?}','SearchController@locations',function($src = null){});
});

and my controller is as follows:

    class SearchController extends BaseController {

    public function locations($src)
    {
        return json_encode($src);
    }

}

I want to know how to pass the parameter to the controller, the code that I have now returns this error

{"error": {"type": "ErrorException", "message": "Missing argument 1 for SearchController :: locations ()", "file": "C: \ wamp \ www \ localsite \ app \ controllers \ SearchController .php "," line ": 5}}

Thank you in advance

        $src = Input::get('q');
        return json_encode($src);
