我正在循环一系列的网址,并想要清理它们.我有以下代码:
# Parse url to remove http,path and check format o_url = URI.parse(node.attributes['href']) # Remove www new_url = o_url.host.gsub('www.','').strip
如何对此进行扩展以删除某些网址中存在的子网域?
解决方法
我刚刚写了一个名为Domainatrix的库.你可以在这里找到它:
http://github.com/pauldix/domainatrix
require 'rubygems' require 'domainatrix' url = Domainatrix.parse("http://www.pauldix.net") 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"
