Multiple pattern in single symfony routing

问题

How to make multiple pattern in single Symfony routing?

Normally we have a routing as

blog:
    pattern:   /
    defaults:  { _controller: AcmeBlogBundle:Blog:index, page: 1 }

Is it possible to have two routing patterns?

Something like

blog:
    #Below pattern to match with '/' or '/index'    
    pattern:   {/ , /index}  
    defaults:  { _controller: AcmeBlogBundle:Blog:index, page: 1 }

Are you using Symfony2? If you are and can use annotations for your routing instead of yml or xml then it's possible to have multiple routes defined along these lines:

/**
* @Route("/");
* @Route("/home");
*/

Then you don't need to duplicate the action method.

The easiest way is to duplicate the block and make 2 routes.

blog:
    pattern:   /
    defaults:  { _controller: AcmeBlogBundle:Blog:index, page: 1 }

blog_index:
    pattern:   /index
    defaults:  { _controller: AcmeBlogBundle:Blog:index, page: 1 }

So you have the possibility to use both of them in your path if you need it.

Here you can see another post how to use regex in your routing. Perhaps you can write a simple regex, which checks whether index is set.

Edit:

If you work with annotations, which I prefer, then you can write more than one route over your Controller's Action method. Something like this:

/**
* @Route("/");
* @Route("/home");
*/

When using YAML routes you can also use the node anchors expression syntax to reference an existing route definition.

& specifies the first occurrence of an anchor, * specifies the anchor to reference, << tells the Symfony yaml parser to merge the specified node.

blog: &blog
  path: /
  defaults:  { _controller: AcmeBlogBundle:Blog:index, page: 1 }

blog_index:
  <<: *blog
  path: /index

blog_page:
  <<: *blog
  path: /blog

Alternatively you can use anchors on a route attribute value.

blog:
  path: /
  defaults: &blog_defaults
    _controller: AcmeBlogBundle:Blog:index
    page: 1

blog_index:
  path: /index
  defaults: *blog_defaults

blog_page:
  path: /blog
  defaults: *blog_defaults

However to prevent poor SEO due to duplicate content, it is recommended to use a redirect instead.

blog:
  path: /
  defaults: { _controller: AcmeBlogBundle:Blog:index, page: 1 }

blog_index:
  path: /index
  defaults: &blog_redirect
    _controller: FrameworkBundle:Redirect:redirect
    route: blog
    permanent: true

blog_page:
  path: /blog
  defaults: *blog_redirect

Just to add to john's answer:

I use it a lot with FOSJsRoutingBundle:

/**
 * @Route("/", name="route_name_1", options={"expose"=true})
 * @Route("/{id}", name="route_name_2", options={"expose"=true})
 * @Method("GET")
 * @Template()
 */

This way I have one method and two routes.

Just remember to set default $id value:

public function indexAction($id = null)
{
   ...
}
