I try handle all excpetions (Symfony 5) via official documentation: https://symfony.com/doc/current/controller/error_pages.html#overriding-error-output-for-non-html-formats
I want serialize all exception to JSON format. I read solution for similar problem in this topic: How to format all HttpExceptions as json in symfony5? but doesn't resolve my problem.
There my files: src/Controller/ShowController.php
<?php
namespace App\Controller;
use App\Component\ShowResponseHandlerInterface;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\BinaryFileResponse;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;
use Symfony\Component\Routing\Annotation\Route;
class ShowController extends AbstractController
{
/**
* @Route("/show/{file}", name="show", requirements={"file"=".+"})
*/
public function index(string $file, string $storageDirectory): Response
{
$absolutePath = $storageDirectory.$file;
if(!file_exists($absolutePath)) {
throw new NotFoundHttpException("Resource not exists");
}
return new BinaryFileResponse($absolutePath);
}
}
src/Serializer/ProblemNormalizer.php
<?php
namespace App\Serializer;
use Symfony\Component\ErrorHandler\Exception\FlattenException;
use Symfony\Component\Serializer\Normalizer\NormalizerInterface;
class ProblemNormalizer implements NormalizerInterface
{
public function normalize($exception, string $format = null, array $context = [])
{
return [
'success' => false,
'exception'=> [
'message' => $exception->getMessage(),
'code' => $exception->getStatusCode(),
]
];
}
public function supportsNormalization($data, string $format = null)
{
return $data instanceof FlattenException;
}
}
config/services.yaml
services:
_defaults:
autowire: true # Automatically injects dependencies in your services.
autoconfigure: true # Automatically registers your services as commands, event subscribers, etc.
App\Serializer\ProblemNormalizer:
tags: ['serializer.normalizer']
and of course i have installed package symfony/serializer
composer show -i | grep "symfony/serializer"
symfony/serializer v5.2.9 Handles serializing and deserializing data structures, including object graphs, into array structures or other formats like XML and JSON
What I'm doing wrong or what is not configured? It always return html output.
Update
Console output for:
symfony console debug:container | grep normalizer
