Question

I am using URI module in ruby to match a URL.

require 'uri'
url = URI"http://matchme.projects.foo.com"

Need to match the matchme part of the url and put it into a variable. The matchme part of the url will always be after http:// and before the next “.projects”.

I am trying url.scheme which gives me “http”, how to proceed from there and match my string.
The matchme part keeps changing all the time.

Answer 1

you can use regular expression like

  "http://matchme.projects.foo.com"[/http:\/\/([a-z0-9\-]*).*/,1]
  => matchme 

or

if request object is available then

 request.subdomains[0]

will give you the deepest sub domain.
