gistfile1.rb

require 'rubygems'
require 'net/http'
require 'net/https'
require 'xmlsimple'
 
# To Ping the server, we'll send a GET request.
@uri = URI.parse("https://my-domain.myhaikuclass.com")
@uri.path   = "/do/services/test/ping"
@uri.query  = "hello=world"

if @uri.is_a?(URI::HTTPS)
  http = Net::HTTP.new(@uri.host, @uri.port)
  http.use_ssl = true
  http.verify_mode = OpenSSL::SSL::VERIFY_NONE
  @response = http.request(
    Net::HTTP::Get.new(@uri.request_uri)
  )
else
  @response = Net::HTTP.get_response(@uri)
end
 
# 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
