Namespace

Code

public function onResponse(ResponseEvent $event) {
  $request = $event->getRequest();
  if ($request->getRequestFormat() !== 'api_json') {
    return;
  }
  // At this point, we've already run validation on the request by checking
  // the query arguments. This means that if the query arguments change, we
  // may need to run this validation again. Therefore, all responses need to
  // vary by url.query_args.
  $response = $event->getResponse();
  if ($response instanceof CacheableResponseInterface) {
    $response->addCacheableDependency((new CacheableMetadata())->addCacheContexts([
      'url.query_args',
