Symfony2：带有斜杠和可选参数的URL [英] Symfony2: URLs with trailing slash and an optional parameter

问题描述

我希望我的应用程序中的所有URL都带有斜杠。我的route.yml中有以下路线：

I want all URLs in my application to have a trailing slash. I have the following route in my route.yml:

foo_route:
    pattern:  /foo/{page}/
    defaults: { _controller: FooBundle:Foo:list, page: 1 }
    requirements:
      page:  \d+

对'/ foo / 1 /'的请求可以正常工作，但是由于URL模式中的斜杠，对'/ foo /'的请求不匹配。

Requests to '/foo/1/' work fine, however requests to '/foo/' are not matched because of the trailing slash in the URL pattern.

如何定义带有斜杠和可选参数的路由？我知道我可以为这两种情况定义2条不同的路线，但是我想避免这种情况。

How can I define routes with trailing slashes and an optional parameter? I am aware I can define 2 different routes for the two cases, but I want to avoid that.

推荐答案

相关案例，您可以匹配以下三种模式：

In a separate but related case, you can match the following three patterns:

/foo
/foo/
/foo/page/1

通过消除路径中的尾部反斜杠并放宽正则表达式以匹配0或更多字符（*），而不是1个或多个（+）：

by eliminating the trailing backslash in the route and relaxing the regular expression to match 0 or more characters (*), instead of 1 or more (+):

foo_route:
    pattern:  /foo/{page}
    defaults: { _controller: FooBundle:Foo:list, page: 1 }
    requirements:
      page:  \d*

但是与/ foo / page / 1 /

However that will not match /foo/page/1/
