Symfony JSON rest API

Symfony stuff to help building a JSON REST api :

• Support JSON payload
• Support LINK headers
• Handle exception as JSON response
• Possibility to validate json payload through json schema
• Possibility to map custom exception to http code

Here is a simple setup to start :

<?xml version="1.0" ?>

<container xmlns="http://symfony.com/schema/dic/services"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://symfony.com/schema/dic/services http://symfony.com/schema/dic/services/services-1.0.xsd">

                </service>
            </argument>
            <tag name="kernel.event_listener" event="kernel.request" method="onKernelRequest" priority="24" />
        </service>

            <tag name="kernel.event_listener" event="kernel.exception" method="onKernelException" priority="32" />
        </service>

            <tag name="kernel.event_subscriber" />
            <tag name="monolog.logger" channel="request" />
            <argument>json_exception_controller.ui:showException</argument>
            <argument type="service" id="logger" on-invalid="null" />
        </service>
    </services>
</container>
