Class

AcceptNegotiation406

View subscriber rendering a 406 if we could not route or render a request.

Namespace

Drupal\Core\EventSubscriber

Code

public function onViewDetect406(GetResponseForControllerResultEvent $event) {
  $request = $event
    ->getRequest();
  $result = $event
    ->getControllerResult();

  // If this is a render array then we assume that the router went with the
  // generic controller and not one with a format. If the format requested is
  // not HTML though we can also assume that the requested format is invalid
  // so we provide a 406 response.
  if (is_array($result) && $request
    ->getRequestFormat() !== 'html') {
    throw new NotAcceptableHttpException('Not acceptable');
  }
