Description
Hi! Sorry in advance if that issue is a duplicate (didn't find anything like it). What if we add new method in AbstractController to deserialize from json (opposite to AbstractController::json()) ? AbstractController already has lots of methods, but still this opertation seem to be routine one while developing APIs :)

Example

protected function fromJson(string $body, string $to, array $context = [])
{
    // check if serializer available
    // return deserialized value
}

...

public function createUser(Request $request)
{
    $resource = $this->fromJson($request->getContent(), UserResource::class);
}

If OK, I would like to implement it.

WDYT? Thanks!
