I tried:

$this->response->body = json_encode($data);

but I get warning: controller should return a string or a Response object, support for the $controller->response object is deprecated.
Should I simply use

echo json_encode($data);

or is there something else I should use?

Heres how the main parts of my ajax controller work, I override the router to check for a csrf token that should be coming with the input vars, if its not there nothing gets routed to a method.

class Controller_Ajax extends Controller_Rest &#123;

    public $params;
    public $response;
    private $user_id;
    private $token;
    private $data;
    private $success;
    private $message;
    private $output;

    public function before($data = null) &#123;

        parent::before();

        if (!Sentry::check()) &#123;
            die('not logged in');
        }

        $this->user_id = Session::get('user_id');

        $this->params = json_decode(stripslashes(Input::post('params')));
        $this->token = Input::post('csrf_token');

        $this->success = false;
        $this->message = null;
        $this->output = null;
        $this->code = 200;
    }

    public function router($resource, array $arguments) &#123;

        $pattern = '/\.(' . implode('|', array_keys($this->_supported_formats)) . ')$/';

        // Check if a file extension is used
        if (preg_match($pattern, $resource, $matches)) &#123;
            // Remove the extension from arguments too
            $resource = preg_replace($pattern, '', $resource);

            $this->format = $matches[1];
        } else &#123;
            // Which format should the data be returned in?
            $this->format = $this->_detect_format();
        }

        if (Security::check_token($this->token) == false) &#123;
            $this->message = 'page has expired, please refresh and try again';
            return;
        }
        // If they call user, go to $this->post_user();
        $controller_method = strtolower(\Input::method()) . '_' . $resource;

        // If method is not available, set status code to 404
        if (method_exists($this, $controller_method)) &#123;
            if (call_user_func_array(array($this, $controller_method), $arguments) == true) &#123;
                $this->success = true;
            }
        } else &#123;
            $this->message = "unknown method $controller_method";
            $this->response->status = 404;
            return;
        }
    }

  
    public function after($response) &#123;
        $this->response(array('success' => $this->success, 'message' => $this->message, 'output' => $this->output), $this->code);
        return parent::after($response);
    }

Ideally, your controller should extend Controller_Rest. Which will take care of all json business for you, internally you just work with arrays.

Quick helper function: function push_json($data=array(),$response=200)
{
$content_type = array('Content-type'=>'application/json'); if($data)
return new \Response(json_encode($data),$response,$content_type);
}
