控制器的自定义错误处理程序，yii2

Question

我有一个控制器“前面”，我只想让这个控制器使用自定义错误操作。 我怎样才能做到这一点？我试过了this，但似乎无法正常工作

Answer 1

我发现这个解决方案可以捕获异常

if ($model == null) {
   // (I want the front layout only for this exception,so this 'throw' seems not to working as I want,it has the 'site' layout of site/error default error action )throw new NotFoundHttpException('The patient does not exist.');
            $exception = new \yii\web\NotFoundHttpException("The patient does not exist");
            $statusCode = $exception->statusCode;
            $name = $exception->getName();
            $message = $exception->getMessage();
            return $this->render('error', [
                        'exception' => $exception,
                        'statusCode' => $statusCode,
                        'name' => $name,
                        'message' => $message
            ]);
