Posting JSON objects to Symfony 2

If you want to retrieve data in your controller that’s been sent as standard JSON in the request body, you can do something similar to the following:

public function yourAction()
{
    $params = array();
    $content = $this->get("request")->getContent();
    if (!empty($content))
    {
        $params = json_decode($content, true); // 2nd param to get as array
    }
}

Now $params will be an array full of your JSON data. Remove the true parameter value in the json_decode() call to get a stdClass object.
