php - Is it possible to restrict a route for AJAX only?

Question

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

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
}

I want to define:

• one rule for AJAX requests
• one rule for GET/POST requests to the same URL

in order to get around having conditions like above.

Answer 1

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

Matching Expressions

For an ajax restriction it would look like this:

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

Also possible in Annotation:

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