FOSRestBundle does not set the _format parameter - symfony

Question

I have the following configuration:
fos_rest:
view:
view_response_listener: 'force'
formats:
json: true
xml: true
html: false
body_listener:
decoders:
json: fos_rest.decoder.json
xml: fos_rest.decoder.xml
body_converter:
enabled: true
format_listener:
enabled: true
rules:
- { path: '^/api', priorities: ['xml', 'json'], fallback_format: xml, prefer_extension: false }
param_fetcher_listener: force
routing_loader:
# default_format: xml
include_format: false
serializer:
serialize_null: true
and the following Controller:
/**
* #Rest\View(serializerGroups={"o-all-getCDashboard"})
*/
public function cgetAction($_format)
{
$handler = $this->getHandler();
die(dump($_format));
return $handler->getAll();
}
within a class that extends FOSRestController implements ClassResourceInterface
which always dumps null. If I re-enable default_format: xml what I get is always xml notwithstanding the Accept header I send. What's wrong with it? Why does not the format_listener work?

You using uncorrected format_listeners config.
Try using my config like this:
fos_rest:
body_listener: true
param_fetcher_listener: true
view:
view_response_listener: 'force'
formats:
jsonp: true
json: true
xml: false
rss: false
mime_types:
json: ['application/json', 'application/x-json']
jpg: ['image/jpeg']
png: ['image/png']
jsonp_handler: ~
routing_loader:
default_format: json
include_format: false
format_listener:
rules:
- { path: /api, priorities: [ json, jsonp ], fallback_format: json, prefer_extension: true }
exception:
enabled: true
Addition just settings section formats and fallback_format for yourself.
In my controller I using
use FOS\RestBundle\Controller\Annotations as Rest;
use FOS\RestBundle\Controller\Annotations\RouteResource;
/**
* #RouteResource("someName")
*/
class myController extends FOSRestController implements ClassResourceInterface {
/**
* #param Request $request
* #Rest\Post("/someLink")
*/
public function insertLinkAction(Request $request) {}
}
I hope that help you.
