Question

I used the following question, Remove "www", "http://" from string , to remove the HTTP and HTTPS from my url. Now I want to remove the path on the end of the url as well and can't seem to get the pattern. This is the code I am trying to use:

str = str.sub(/^https?\:\/\//, '').sub(/^www./,'').sub(/^\/*/,'')

The first two .sub work as expected and remove the HTTP , HTTPS and www. from the url but the path ie http://URL/path/to/remove/ stays with the URL. As can be seen above I have tried the following pattern /^\\/*/ in the third sub but it doesn't remove the path on the end of the url. What pattern will remove all characters after the base URL?

You could:

require 'uri'
URI('http://stackoverflow.com/questions/24252071/ruby-editing-urls').host
# => "stackoverflow.com"
