您可以使用URI模块https://docs.ruby-lang.org/en/2.1.0/URI.html
uri = URI("http://foo.com/posts?id=30&limit=5#time=1305298413")
uri.host
#=> "foo.com"

请尝试如下所示的URI模块:-
require 'uri'
uri = URI("http://foo.com/posts?id=30&limit=5#time=1305298413")
#=> #<URI::HTTP:0x00000000b14880
URL:http://foo.com/posts?id=30&limit=5#time=1305298413>
uri.scheme
#=> "http"
uri.host
#=> "foo.com"
uri.path
#=> "/posts"
uri.query
#=> "id=30&limit=5"
uri.fragment
#=> "time=1305298413"
uri.to_s
#=> "http://foo.com/posts?id=30&limit=5#time=1305298413"
谢谢:)
