从 URL 字符串中提取主机的 Ruby 代码 [英] Ruby code to extract host from URL string

问题描述

我正在寻找一种方法来可靠地从 Ruby 中的 URL 字符串中提取主机名.

I'm looking for a method to reliably extract the host name from a URL string in Ruby.

例如http://www.mglenn.com/directory = www.mglenn.com或者http://www.mglenn.com?param=x = www.mglenn.com

e.g. http://www.mglenn.com/directory = www.mglenn.com OR http://www.mglenn.com?param=x = www.mglenn.com

推荐答案

你可以试试这样的:

require 'uri'

myUri = URI.parse( 'http://www.mglenn.com/directory' )
print myUri.host
# =>  www.mglenn.com
