How to get the content of twig file

This is what I am trying to do

 public function editAction(Request $request, Uni $uni){
        $template = $this->forward('AppBundle:Uni:edit.html.twig')->getContent();

        $json = json_encode($template);
        $response = new Response($json, 200);
        $response->headers->set('Content-Type', 'application/json');
        return $response;
}

Basically, I am trying to get the content of edit.html.twig file. Unfortunately, I am not getting the expected content from edit.html.twig file. How can I get this content?

Location of edit.html.twig file is in testproject/app/Resources/uni/edit.html.twig

You can also use the render helper directly:

use Symfony\Component\HttpFoundation\JsonResponse;

public function editAction(Request $request, Uni $uni)
{
    return $this->render('AppBundle:Uni:edit.html.twig', [
        'uni' => $uni,
    ], new JsonResponse());
}

The simplest way to get the contents of a twig template from inside a controller would be using renderView helper method.

Another improvement you can make to your code is to use symfony's JsonResponse class to return your JSON. Example:

use Symfony\Component\HttpFoundation\JsonResponse;

public function editAction(Request $request, Uni $uni)
{
    $template = $this->renderView('AppBundle:Uni:edit.html.twig', [
        'uni' => $uni,
    ]);

    return new JsonResponse($template);
}
