Is it possible to create a route that points to an absolute external URL?

问题

Google, as well as Symfony Docs and Cookbook haven't helped.

Let's say we have a website called http://www.example.com that is running on Symfony2 and we are using an external FAQ and Support Service (for whatever reason) located at http://example.externalservice.com.

We now thought it would be a suitable solution to create a route that points to the external FAQ service which would result in something like that:

# ../config/routing.yml
[...]

info.faq:
    url: http://example.externalservice.com     # Surely isn't working

[...]

This, because there could be a need to replace the support service with a home-brewed solution located within the application in the medium term. This route is used on various pages, so hardcoding or replacing them all when the support service changes is not an option.

So, my questions are:

Is this the right approach or should we be using a TWIG extension and a parmeter located either in parameters.yml or config.yml?
If it is the right approach, is it possible to create such a route without modifying the routing component itself?

Thank you in advance.

回答1:

In your parameters.yml add

external_url: http://example.externalservice.com

then in your controller :

$url = $this->container->getParameter('external_url');
return $this->redirect($url);

From the Symfony2 documentation:

root:
    path:  /
    defaults:
        _controller: FrameworkBundle:Redirect:urlRedirect
        path: http://www.google.fr
        permanent: true
