JSON exception in cakephp 3

Question

I'm doing a restfull api in cakephp... And sometime i have some throw exceptions. For example:

if (!$this->request->is('post')) {
            throw new MethodNotAllowedException("The requested resource does not support http method " . $this->request->param('_method'));
        }

My problem is when the url is /controller/action.json the response is :

{
message: "The requested resource does not support http method GET",
url: "/api/auth/users/authenticate.json",
code: 405
}

In json format, but, when my url is /controller/action. My response is HTML, i want to know if is possible to force these exceptions to be always json without putting .json in the url.

Thanks!

Answer 1

You can force exceptions to be always rendered in json adding in Controller/ErrorController.php (in beforeRender)

$this->RequestHandler->renderAs($this, 'json');
