AngularsJS POST JSON data to Symfony2 - ajax

Question

I would like to know why this is not working , I have a AngularJS app witch sends trough AJAX data to a Symfony2 Application. As you can see, data is sent in my network console
<?php
namespace Supbox\CloudBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\JsonResponse;
class FolderController extends Controller
{
public function createAction(){
$post = $this->getRequest()->request;
$name = $post->get("name");
$folder = $post->get("folder");
var_dump($post);
die;
}
}
AngularJS code
$http({
method: 'POST',
url: route.folder.create,
data: {
folder: $scope.id,
name: name
}
})
Opera Network Console Output

Answer 1

If you (Angular JS) post data through header as JSON you need to change your code like this:
public function createAction(){
$post = $this->getRequest()->getContent();
$post = json_decode($post);
$name = $post->name;
$folder = $post->folder;
var_dump($post);
var_dump($name); // null
var_dump($folder); // null
die;
}

Dont know why, Angular $http sends data as request body, JSON encoded whereas Symfony2 is reading $_GET and $_POST arrays.
So you got 2 solutions:
1- Update Php code, you could override SF2 Request class (https://gist.github.com/ebuildy/fe1e708e466dc13dd736)
2- Update Js code, you can "transform" the $http request (https://gist.github.com/bennadel/11212050)

A bundle has been created to solve this problem, and it's very light.
