_format
ルートを手動で記述し、次のように設定できます。
acme_demo.api.user:
type: rest
pattern: /user/{username_canonical}.{_format}
defaults: { _controller: 'AcmeDemoBundle:User:getUser', username_canonical: null, _format: json }
requirements:
_method: GET
編集:または、独自の例外ハンドラーを記述して、必要なことは何でも例外で行うことができます。
// src/Acme/DemoBundle/EventListener/AcmeExceptionListener.php
namespace Acme\DemoBundle\EventListener;
use Symfony\Component\HttpKernel\Event\GetResponseForExceptionEvent;
use Symfony\Component\HttpFoundation\JsonResponse;
use Symfony\Component\HttpKernel\Exception\HttpExceptionInterface;
class AcmeExceptionListener
{
public function onKernelException(GetResponseForExceptionEvent $event)
{
// do whatever tests you need - in this example I filter by path prefix
$path = $event->getRequest()->getRequestUri();
if (strpos($path, '/api/') === 0) {
return;
}
$exception = $event->getException();
$response = new JsonResponse($exception, 500);
// HttpExceptionInterface is a special type of exception that
// holds status code and header details
if ($exception instanceof HttpExceptionInterface) {
$response->setStatusCode($exception->getStatusCode());
$response->headers->replace($exception->getHeaders());
}
// Send the modified response object to the event
$event->setResponse($response);
}
}
