As this is a method being called in a controller route, we can just pass in Request as a magic parameter, instead of using \Drupal::request()

Have a look at \Drupal\aggregator\Routing\AggregatorController::feedRefresh() http://drupalcode.org/project/drupal.git/blob/HEAD:/core/modules/aggrega...

The Request parameter can be passed into the method (in any order) and you don't need to specify it in your route configuration.

Looking good!
