Cakephp 3中的JSON异常 [英] JSON exception in cakephp 3

问题描述

我正在用cakephp做一个restfull api ... 有时我会抛出一些异常.例如:

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'));
        }

我的问题是，当url为/controller/action.json时，响应为:

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
}

采用json格式，但是当我的网址是/controller/action时.我的回应是HTML，我想知道是否有可能在不将.json放入url的情况下强制将这些异常始终设置为json.

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.

谢谢！

推荐答案

您可以强制将异常始终在json中呈现，并添加到 Controller/ErrorController.php (在beforeRender中)

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

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