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}
这两个参数都是可选的 - 因此以下方案必须有效:
www.myaweseomesite.com/payment/customer/{customerNumber}/{invoiceNumber}
www.myaweseomesite.com/payment/customer/{customerNumber}
www.myaweseomesite.com/payment/customer/{invoiceNumber}
我根据symfony2 doc设置了routing.yml。
payment_route:
pattern: /payment/customer/{customerNumber}/{invoiceNumber}
defaults: { _controller: PaymentBundle:Index:payment, customerNumber: null, invoiceNumber: null }
requirements:
_method: GET
到目前为止这种方法很有效。问题是,如果两个参数都缺失或为空,则路由不起作用。所以
www.myaweseomesite.com/payment/customer/
不应该工作。有没有办法用Symfony2做到这一点?

您可以在两条路线中定义它,以确保只有一条斜线。
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
请注意,您可能需要根据具体需要更改定义参数的正则表达式。你可以look at this。复杂的正则表达式必须被"
包围。 (示例myvar : "[A-Z]{2,20}"
)

要详细说明@Hugo的答案,请在下面的配置中找到注释:
/**
* @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 }

根据文件:
http://symfony.com/doc/current/routing/optional_placeholders.html
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)
{
// ...
}
这样你在routing.yml
中只需要一个路由
