Remove “www”, “http://” from string

Question

How can I remove \"www\", \"http://\", \"https://\" from strings using Ruby?

I tried this but it didn\'t work:

s.gsub(\'/(?:http?:\\/\\/)?(?:www\\.)?         


        

Answer 1

def strip_url(target_url)
  target_url.gsub("http://", "")
            .gsub("https://", "")
            .gsub("www.", "")
end

strip_url("http://www.google.com")
 => "google.com" 
strip_url("https://www.google.com")
 => "google.com" 
strip_url("http://google.com")
 => "google.com"
strip_url("https://google.com")
 => "google.com" 
strip_url("www.google.com")
 => "google.com"
