提取後綴

Question

我需要從URL中提取的後綴，這意味着：

http://google.com/sports/golf =>運動/高爾夫 http://yahoo.com/blog?id=7 =>博客/ ID = 7

我怎麼能acheive與正則表達式（紅寶石樣式）？

謝謝

Answer 1

使用URI模塊.path + .query。

uri = URI("http://google.com/sports/golf") 
uri.path + "/" + uri.query 

Answer 2

如何爲以下：:)

require 'uri' 
p URI.split("http://google.com/sports/golf").compact.drop(2).join("/") 
p URI.split("http://yahoo.com/blog?id=7").compact.drop(2).join("/") 

或者，

require 'uri' 

a = ["http://google.com/sports/golf","http://stackoverflow.com/questions/15766337/extract-suffix-from-url-regex/15766456#15766456","http://yahoo.com/blog?id=7"] 
a.each { |url| p URI.split(url).compact.drop(2).join("/") } 

輸出：

"/sports/golf" 
"https://stackoverflow.com/questions/15766337/extract-suffix-from-url-regex/15766456/15766456" 
"/blog/id=7" 

Answer 3

試試這個：

irb(main):011:0> /(?:http:\/\/\w+\.\w+\/)(.+)/.match("http://yahoo.com/blog?id=7")[1] 
=> "blog?id=7" 
irb(main):012:0> /(?:http:\/\/\w+\.\w+\/)(.+)/.match("http://google.com/sports/golf")[1] 
=> "sports/golf" 
irb(main):013:0>
