gistfile1.rb

require 'rubygems'
require 'oauth'
require 'xmlsimple'

# Create an OAuth Consumer with the appropriate API key and secret.
@consumer = OAuth::Consumer.new("api_key_EUNzNgVkrpFUFg", "api_secret_KBq6hTvjjvqAWOPz6c4WnQHN6jvkU8", { :site=>"https://my-domain.myhaikuclass.com" })

# Create an OAuth Access Token using your personal key and secret.
@access_token = OAuth::AccessToken.new(@consumer, "token_959b3659b65ddbb6f8552c3401", "secret_40ec1d3617e7f58811c2f1e4416dcf2f7")

# In order to test OAuth authentication on the server, we'll send a GET request.
@response = @access_token.get("/do/services/test/oauth?hello=world")

# Parse the XML response.
@response = XmlSimple.xml_in(@response.body)

if @response['status'] == 'ok'
  # If the response from the Haiku LMS API indicates success
  # extract the pong and display it.
  @pong = @response['pong']
  puts @pong.inspect
  # [{
  # "hello"=>"world"
  # }]
else
  # If there was an error, display the error message
  @error = @response['error'].first
  message = "API Error #{ @error['code'] }: #{ @error['description'] }"
  message += "\n#{ @error['details'] }" if @error['details']
  raise message
end
