FinalRedirectUrl

Ruby gem to get a final redirect url for any given url.

Installation

Add this line to your application's Gemfile:

gem 'final_redirect_url'

And then execute:

$ bundle

Or install it yourself as:

$ gem install final_redirect_url

Usage

NOTE: The input url must start with http/https protocol.

FinalRedirectUrl.final_redirect_url('http://www.google.com')

From IRB:

2.4.0 :001 > require 'final_redirect_url'
 => true
 
# No protocol provided
2.4.0 :002 > FinalRedirectUrl.final_redirect_url('www.google.com')
 => ""

# With valid protocol
2.4.0 :003 > FinalRedirectUrl.final_redirect_url('http://google.com')
redirected to http://www.google.co.in/?gfe_rd=cr&ei=J-cOWYKhCKb98wfOsb2ADA
 => "http://www.google.co.in/?gfe_rd=cr&ei=J-cOWYKhCKb98wfOsb2ADA"

# URI with invalid response
2.4.0 :004 > FinalRedirectUrl.final_redirect_url('http://api.google.com')
E, [2017-05-07T14:52:39.497203 #1358] ERROR -- : bad URI(is not URI?):
 => ""

Usually the gem checks for redirect upto 10 depth level. However you can pass {depth: 20} to check redirects upto 20 depth.
