Today we use URI . Simply require the library and you will be able to parse your current dynamic and static URI any way you please. For example I have a function that can read URI parameters like so...

---

#{RAILS_ROOT}/app/helpers/application_helper.rb (The literal path string of the file depicted below)

def read_uri(parameter)
  require 'uri'
  @raw_uri = URI.parse(request.original_fullpath)
  @uri_params_raw = @raw_uri.query
  if @uri_params_raw =~ /\=/
    @uri_vars = @uri_params_raw.split('=')
    return @uri_vars[parameter]
  end
  return false
end

This should split all URI parameters into an array that gives the requested (numeric) "parameter". I believe that simply the URI.parse(request.original_fullpath) should work for you. I come from using a minimum of rails 4.2.6 with this method so, I hope it works for anyone who might view this later on. Oh, and just as a disclaimer: I wasn't so wise to rails at the time of posting this.
