SWT Federation for Ruby¶ ↑

<img src=“https://secure.travis-ci.org/nicopaez/SWT-Federation.png?branch=master” alt=“Build Status” />

This library provides SWT-based federation for Ruby applications (ruby 1.9)

The entry point of this library is the TokenHandler class. Before using it you have to set some class instance variables that hold configuration information. You can do this, int he config.ru file as shown below.

# config.ru
require './application.rb'
require 'swt_federation'

SwtFederation::TokenHandler.realm = 'yourrealmhere'
SwtFederation::TokenHandler.issuer = 'https://yourservicenamespacehere.accesscontrol.windows.net/'
SwtFederation::TokenHandler.token_key = 'yourkeyhere'
SwtFederation::TokenHandler.token_type = 'http://schemas.xmlsoap.org/ws/2009/11/swt-token-profile-1.0'

run Sinatra::Application

Below you can find an example of how to use it with Sinatra.

# application.rb
before do

  next if request.path_info == '/swt' 
  if(session['user']==nil)
    redirect ("<your_identity_provider_url>")
  end
end

post '/swt' do
  response = TokenHandler.new(params[:wresult])
  if (response.is_valid?)
    session['user'] = response.claims['http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress']
    target_url = params[:wctx]
    if (target_url != nil)   
      redirect(target_url)
    else
      redirect('/home') 
    end
  else
    status(403)
    halt('access denied')
  end
end

get '/'
  user = session['user']
  "Hello #{user}!"
end

This is the second drop, I have added some tests and now there is a good coverage rate but there are many things to improve(check coding conventions, add more features, deeper Rack integration, etc). If you want to use it and have any doubt, just contact me.

Hope you find it useful!
