如何从红宝石中获取网址的网站名称？

Question

我有一个网址,如:

http://www.relevantmagazine.com/life/relationship/blog/23317-pursuing-singleness 

并希望从中提取相关的杂志.

目前我有:

@urlroot = URI.parse(@link.url).host

但它返回www.relevantmagazine.com 任何人都可以帮助我吗？

使用宝石可能有点矫枉过正,但无论如何:有一个名为domainatrix的方便宝石,它可以为你处理像两个元素顶级域等的东西时提取网站名称.

url = Domainatrix.parse("http://www.pauldix.net")
url.url       # => "http://www.pauldix.net" (the original url)
url.public_suffix       # => "net"
url.domain    # => "pauldix"
url.canonical # => "net.pauldix"

url = Domainatrix.parse("http://foo.bar.pauldix.co.uk/asdf.html?q=arg")
url.public_suffix       # => "co.uk"
url.domain    # => "pauldix"
url.subdomain # => "foo.bar"
url.path      # => "/asdf.html?q=arg"
url.canonical # => "uk.co.pauldix.bar.foo/asdf.html?q=arg"
