README

This bundle can listen to exception that reach the kernel of Symfony to transform them before the kernel render them. This is useful when you want to transform domain/business exception from your code to presentation exception such as http exception that contain http status code.

Usage

Require the dependency in your composer.json

For symfony >=4 and php >=7.4

"riper/exception-transformer" : "2.*"

For symfony <4 and php <7.4

"riper/exception-transformer" : "1.*"

Register the bundle in app-kernel

new Riper\Bundle\ExceptionTransformerBundle\RiperCommonExceptionTransformerBundle(),

Transform exception with a service (most portable way)

Implement the interface \Riper\Bundle\ExceptionTransformerBundle\ExceptionTransformer\ExceptionTransformerInterface

Implement the transform method. It can (if required) throw a new exception according to the exception given.

Example :

<?php
namespace Riper\Bundle\Moderation\AmoBundle\Exceptions;


use Riper\Bundle\Accounts\AuthenticationBundle\Exceptions\NotFoundException;
use Riper\Bundle\ExceptionTransformerBundle\ExceptionTransformer\ExceptionTransformerInterface;
use Symfony\Component\HttpKernel\Exception\BadRequestHttpException;
use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;

class ExceptionTransformer implements ExceptionTransformerInterface
{
    /**
     * {@inheritdoc}
     */
    public function transform(\Exception $exception)
    {
        switch (1){
          case $exception instanceof NotFoundException :
              throw new NotFoundHttpException($exception->getMessage(),$exception);
          case $exception instanceof InvalidParametersException :
              throw new BadRequestHttpException($exception->getMessage(),$exception);
        }
    }
}

Create a service description tagged with the following information

• name : riper.exception.transformer
• scope: [The namespace the transformer will be restricted to]

example :

riper.moderation.exception.transformer:
    class: Riper\Bundle\biduleBundle\Exceptions\ExceptionTransformer
    tags:
        - { name: riper.exception.transformer , namespace_scope: "Riper\\Bundle\\Bidule\\"}

Use the built-in transformer for http error exception

You can transform your exceptions in httpException from symfony/http-kernel just by adding some configuration. No code needed.

1. Create a configuration key in parameters with a unique name ending by "riper_exception_map".
2. The parameter contain a key=>value with
   • key = THe full namespace of the exception to transform (without a slash at the beginning)
   • value = The http status to generate (an exception will be thrown with the proper http status code)

The list of available status is located in riper_exception_mapping.shortcuts parameter in ExceptionTransformerBundle/Resources/config/exceptions_mapping.yml. The following is a non-exhaustive list

• BadRequestHttpException
• NotFoundHttpException
• ConflictHttpException
• AccessDeniedHttpException
• GoneHttpException
• LengthRequiredHttpException
• MethodNotAllowedHttpException
• NotAcceptableHttpException
• PreconditionFailedHttpException
• PreconditionRequiredHttpException
• UnprocessableEntityHttpException
• UnsupportedMediaTypeHttpException

Example :

parameters:
    customercare.contact.riper_exception_map:
        Riper\Bundle\CustomerCare\ContactBundle\Exceptions\InvalidParameterException: BadRequestHttpException
        Riper\Bundle\CustomerCare\ContactBundle\Exceptions\ContactException: BadRequestHttpException

The status code/exception is not in the shortcut list ? use the first method with the transformer tagged
