Symfony2 Routing: Two optional parameters - at least one required
提问by marty
I'm trying to set up some routes in symfony2 for the following pattern:
我正在尝试在 symfony2 中为以下模式设置一些路由：
www.myaweseomesite.com/payment/customer/{customernumber}/{invoicenumber}
Both parameters are optional - so the following scenarios must work:
这两个参数都是可选的 - 因此以下场景必须适用：
www.myaweseomesite.com/payment/customer/{customerNumber}/{invoiceNumber}
www.myaweseomesite.com/payment/customer/{customerNumber}
www.myaweseomesite.com/payment/customer/{invoiceNumber}
I set up my routing.yml according to the symfony2 doc.
我根据symfony2 doc设置了我的 routing.yml 。
payment_route:
pattern: /payment/customer/{customerNumber}/{invoiceNumber}
defaults: { _controller: PaymentBundle:Index:payment, customerNumber: null, invoiceNumber: null }
requirements:
_method: GET
This works great so far. The problem is, that if both parameters are missing or empty, the route should not work. So
到目前为止，这很好用。问题是，如果两个参数都丢失或为空，则路由不应该工作。所以
www.myaweseomesite.com/payment/customer/
should not work. Is there any way to do this with Symfony2?
不应该工作。有没有办法用 Symfony2 做到这一点？

You can define it in two routes to be sure to have only 1 slash.
您可以在两条路线中定义它以确保只有 1 个斜线。
payment_route_1:
pattern: /payment/customer/{customerNumber}/{invoiceNumber}
defaults: { _controller: PaymentBundle:Index:payment, invoiceNumber: null }
requirements:
customerNumber: \d+
invoiceNumber: \w+
_method: GET
payment_route_2:
pattern: /payment/customer/{invoiceNumber}
defaults: { _controller: PaymentBundle:Index:payment, customerNumber: null }
requirements:
invoiceNumber: \w+
_method: GET
Please note that you might have to change the regex defining the parameters depending of your exact needs. You can look at this. Complex regex have to be surrounded by ". (Example myvar : "[A-Z]{2,20}")
请注意，您可能必须根据您的具体需要更改定义参数的正则表达式。你可以看看这个。复杂的正则表达式必须被". （示例myvar : "[A-Z]{2,20}"）

To elaborate on @Hugo answer, please find below the config with annotations :
要详细说明@Hugo 的答案，请在带有注释的配置下方找到：
/**
* @Route("/public/edit_post/{post_slug}", name="edit_post")
* @Route("/public/create_post/{root_category_slug}", name="create_post", requirements={"root_category_slug" = "feedback|forum|blog|"})
* @ParamConverter("rootCategory", class="AppBundle:Social\PostCategory", options={"mapping" : {"root_category_slug" = "slug"}})
* @ParamConverter("post", class="AppBundle:Social\Post", options={"mapping" : {"post_slug" = "slug"}})
* @Method({"PUT", "GET"})
* @param Request $request
* @param PostCategory $rootCategory
* @param Post $post
* @return array|\Symfony\Component\HttpFoundation\RedirectResponse
*/
public function editPostAction(Request $request, PostCategory $rootCategory = null, Post $post = null)
{ Your Stuff }

As per documentation:
根据文档：
http://symfony.com/doc/current/routing/optional_placeholders.html
http://symfony.com/doc/current/routing/optional_placeholders.html
set a default value for optional parameters in the annotations in the controller:
在控制器的注释中为可选参数设置默认值：
/**
* @Route("/blog/{page}", defaults={"page" = 1})
*/
public function indexAction($page)
{
// ...
}
This way you only need one route in routing.yml
这样你只需要routing.yml中的一个路由
