Convert Shorten URL (bit.ly, tinyurl, ow.ly, and many more) to Full URL in Ruby

You might worry to visit directly to a shorten URL because who knows it may contain some malicious script/code

I’ve found a solution “Python: Convert those TinyURL (bit.ly, tinyurl, ow.ly) to full URLS” in stackoverflow.com but the code is in Python.

Here is how you can perform the conversion in Ruby

require 'net/http'
def ConvertToFull(tinyurl)
   url = URI.parse(tinyurl)
   host, port = url.host, url.port if url.host && url.port
   req = Net::HTTP::Get.new(url.path)
   res = Net::HTTP.start(host, port) {|http|  http.request(req) }
   return res.header['location']
puts ConvertToFull('http://bit.ly/rgCbf') #here is how you can call the function. Thank you Captain Obvious!

I’ve work on a more complete version which can determine Shorten URL or Full URL and return the full URL for the shorten URL.. email for for the code 😉
