Posting JSON objects to Symfony 2

Question

I\'m working on a project using Symfony 2, I\'ve built a bundle to handle all my database services which passes JSON data back and forward.

My Problem/Question:

Answer 1

I wrote method to get content as array

protected function getContentAsArray(Request $request){
    $content = $request->getContent();

    if(empty($content)){
        throw new BadRequestHttpException("Content is empty");
    }

    if(!Validator::isValidJsonString($content)){
        throw new BadRequestHttpException("Content is not a valid json");
    }

    return new ArrayCollection(json_decode($content, true));
}

And I use this method as shown below

$content = $this->getContentAsArray($request);
$category = new Category();
$category->setTitle($content->get('title'));
$category->setMetaTitle($content->get('meta_title'));
