Question

This is my first day to have fun with Symfony and drupal 8, so please excuse me if my question is very obvious.

With drupal 7:

drupal_json_output(array('products' => array_values($products)));
exit; 

the json output is clean:

{"products":["item_1","item_2",....]}

With drupal 8:

use Symfony\Component\HttpFoundation\JsonResponse; 
// some process
print new JsonResponse(array('products' => array_values($products)));
exit;

It outputs with the headers:

HTTP/1.0 200 OK
Cache-Control: no-cache
Content-Type:  application/json
Date:          Wed, 18 Jul 2012 07:53:26 GMT

{"products":["item_1","item_2",....]}

How do you get rid of those headers?

I am stuck to read the reference here.

Any hint is very much appreciated.

Answer 1

You can get only the “content” of a response by calling $response->getContent().

In your case you could do

use Symfony\Component\HttpFoundation\JsonResponse; 
// some process
$response = new JsonResponse(array('products' => array_values($products)));
print $response->getContent();
exit;

However, be aware that this would be a bad practice because you would lose the response headers in the process, and wouldn’t tell for example, what the content-type of you response is (in this case: “application/json”) etc …

I do not know how to do this properly with drupal, any tips is appreciated.
