是否有可能限制对AJAX只是一个途径？ [英] Is it possible to restrict a route for AJAX only?

问题描述

是否有可能限制一个Symfony的2路线只有XHR请求？我想声明的路线，这是只有通过AJAX访问。

Is it possible to restrict a Symfony 2 route for XHR requests only? I want to declare routes, which are only accessible via AJAX.

我不希望把一些额外的线路到每个AJAX的特定操作，如认为：

I do not want to put some extra lines into each AJAX-specific-actions like that:

if ($request->isXmlHttpRequest()) {
    // do something
} else {
    // do something else
}

我要定义：

• 在一个规则的AJAX请求
• 在一个规则的GET / POST请求相同的URL

为了避开具有条件，比如上面。

in order to get around having conditions like above.

推荐答案

我知道这个问题是一个年纪大一点，但同时一个新途径，以实现这一目标被引入的中的Symfony 2.4

I know this question is a bit older but meanwhile a new way to achieve this was introduced in Symfony 2.4.

有关一个Ajax限制，它是这样的：

For an ajax restriction it would look like this:

contact:
    path:     /contact
    defaults: { _controller: AcmeDemoBundle:Main:contact }
    condition: "request.isXmlHttpRequest()"

也有可能在注释：

Also possible in Annotation:

/**
 * ContactAction
 *
 * @Route("/contact", name="contact", condition="request.isXmlHttpRequest()")
 */
