您可以手动编写你的路由,并设置_format
有这样的:
acme_demo.api.user:
type: rest
pattern: /user/{username_canonical}.{_format}
defaults: { _controller: 'AcmeDemoBundle:User:getUser', username_canonical: null, _format: json }
requirements:
_method: GET
编辑:或者你可以写自己的异常处理程序,并与任何你需要做的例外做到:
// 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);
}
}
并将其注册为一个监听器:
# app/config/config.yml
services:
kernel.listener.your_listener_name:
class: Acme\DemoBundle\EventListener\AcmeExceptionListener
tags:
- { name: kernel.event_listener, event: kernel.exception, method: onKernelException }

您是否在更改config.yml后清除了缓存? – Sethunath 2013-03-13 13:50:10
我总是在变化之后做到这一点。 – mrzepinski 2013-03-13 14:00:45
