Symfony2，检查动作是否被ajax调用 [英] Symfony2, check if an action is called by ajax or not

问题描述

对于控制器中的每个动作，我都需要检查这些动作是否由ajax请求调用.

I need, for each action in my controller, check if these actions are called by an ajax request or not.

如果是，则不添加任何内容，如果否，则需要重定向到主页.

If yes, nothing append, if no, i need to redirect to the home page.

我刚刚找到了 if($ this-> getRequest()-> isXmlHttpRequest())，但是我需要在每个操作上添加此验证..

I have just find if($this->getRequest()->isXmlHttpRequest()), but i need to add this verification on each action..

您知道更好的方法吗?

推荐答案

非常简单！

只需在您的方法中添加$ request变量即可使用.(对于每个控制器)

Just add $request variable to your method as use. (For each controller)

<?php
namespace YOUR\Bundle\Namespace

use Symfony\Component\HttpFoundation\Request;

class SliderController extends Controller
{

    public function someAction(Request $request)
    {
        if($request->isXmlHttpRequest()) {
            // Do something...
        } else {
            return $this->redirect($this->generateUrl('your_route'));
        }
    }

}

如果要自动执行此操作，则必须定义一个内核请求侦听器.

If you want to do that automatically, you have to define a kernel request listener.
