I'm looking for a method to reliably extract the host name from a URL string in Ruby.
我正在寻找一种从Ruby中的URL字符串中可靠地提取主机名的方法。
e.g. http://www.mglenn.com/directory = www.mglenn.com OR http://www.mglenn.com?param=x = www.mglenn.com
例如http://www.mglenn.com/directory = www.mglenn.com或http://www.mglenn.com?param=x = www.mglenn.com
