Question

我使用 FOSRestBundle 将错误消息格式转换为 JSON 。

这是config.yml中的 fos_rest 和 twig 配置部分：

public function showAction(Request $request, $exception, DebugLoggerInterface $logger = null)

    {

        if (!$exception instanceof DebugFlattenException && !$exception instanceof HttpFlattenException) {
            throw new \InvalidArgumentException(sprintf(
                'ExceptionController::showAction can only accept some exceptions (%s, %s), "%s" given',
                'Symfony\Component\HttpKernel\Exception\FlattenException',
                'Symfony\Component\Debug\Exception\FlattenException',
                get_class($exception)
            ));
        }

        try {
            $format = $this->getFormat($request, $request->getRequestFormat());
        } catch (\Exception $e) {
            $format = null;
        }
        if (null === $format) {
            $message = 'No matching accepted Response format could be determined, while handling: ';
            $message .= $this->getExceptionMessage($exception);

            return $this->createPlainResponse($message, Codes::HTTP_NOT_ACCEPTABLE, $exception->getHeaders());
        }

        $currentContent = $this->getAndCleanOutputBuffering($request);
        $code = $this->getStatusCode($exception);
        $viewHandler = $this->container->get('fos_rest.view_handler');
        $parameters = $this->getParameters($viewHandler, $currentContent, $code, $exception, $logger, $format);
        $showException = $request->attributes->get('showException', $this->container->get('kernel')->isDebug());

        try {
            if (!$viewHandler->isFormatTemplating($format)) {
                $parameters = $this->createExceptionWrapper($parameters);
            }

            $view = View::create($parameters, $code, $exception->getHeaders());
            $view->setFormat($format);

            if ($viewHandler->isFormatTemplating($format)) {
                $view->setTemplate($this->findTemplate($request, $format, $code, $showException));
            }

            $response = $viewHandler->handle($view);
        } catch (\Exception $e) {
            $message = 'An Exception was thrown while handling: ';
            $message .= $this->getExceptionMessage($exception);
            $response = $this->createPlainResponse($message, Codes::HTTP_INTERNAL_SERVER_ERROR, $exception->getHeaders());
        }

        return $response;
    }

问题在于所有页面（即使状态代码= 200）都被转换，而且不仅在发生错误时（404,500，...）

已编辑： 我使用了FOSRestBundle的 ExceptionController 的默认 showAction ：

{{1}}

在JSON上仅显示404错误消息（FOSRestBundle）
