Customize serializer

You can customize serializer for change input and output format. For example:

<?php

namespace AgentSIB\JsonRpcBundle\Server;

use AgentSIB\JsonRpc\JsonRpcException;
use AgentSIB\JsonRpc\Serializers\JsonRpcSerializerInterface;
use Symfony\Component\DependencyInjection\ContainerInterface;
use Symfony\Component\HttpFoundation\JsonResponse;
use Symfony\Component\HttpFoundation\Request;

class SymfonyJsonRpcSerializer implements JsonRpcSerializerInterface
{
    /**
     * [@inheritdoc](https://github.com/inheritdoc)
     */
    public function parseRequest ($request)
    {
        if ($request instanceof Request) {
            return [@json_decode](https://github.com/json_decode)($request->getContent(), false, 32);
        }
        throw new JsonRpcException(JsonRpcException::ERROR_PARSE_ERROR);
    }

    /**
     * [@inheritdoc](https://github.com/inheritdoc)
     */
    public function serializeResponse ($response)
    {
        return new JsonResponse($response);
    }
}

As well, you can use additional checks. For example:

// ...
public function parseRequest ($request)
{
    if (!$this->checkSignature($request->getContent())) {
        throw new JsonRpcException(JsonRpcException::ERROR_INVALID_REQUEST);
    }
    if ($request instanceof Request) {
        return [@json_decode](https://github.com/json_decode)($request->getContent(), false, 32);
    }
    throw new JsonRpcException(JsonRpcException::ERROR_PARSE_ERROR);
}
// ...
