Rails路由将完整的主机名与多个主机名匹配 [英] Rails routes match full hostname with multiple period in between

问题描述

我正在尝试匹配以下网址

I'm trying to match a URL something like

http://example.com/this.is.my.full.hostname/something/else

显然，当我在routes.rb文件中传递参数时无法识别此参数

apparently when I pass the param in the routes.rb file it doesn't recognize this parameter

我的代码显示以下内容

match '/:computer_hostname/somethingelse' => 'test#info'

任何想法是实现我上面想要的URL的正确方法是什么？甚至有可能吗？我知道URL中允许使用句点字符，但它允许多个字符吗？

any ideas what's the right way to achieve the URL I wanted above ? Or is it even possible ? I know period is allowed character in URL but does it allow more than one ?

推荐答案

我认为约束方法/选项将帮助您。尝试执行以下操作：

I think the constraints method/option will help you out. Try something like the following:

match ':hostname/something/else' => 'test#info',
  :constraints => {:hostname => /[A-Za-z0-9\._\-]+/}

如果您正在使用相同的：hostname 段进行多个匹配，那么您可以将它们包装在一个约束方法调用中：

If you're doing multiple matches all with the same :hostname segment, then you can wrap them in a constraints method call:

constraints(:hostname => /[A-Za-z0-9\._\-]+/) do
  match ':hostname/something/else' => 'test#info'
  match ':hostname/foo/bar'        => 'test#foo'
end
