The methodology is very simple.

  1. Redirect the user to grant access to your app for a particular Google service.
  2. Once access is granted, use the authentication token to retrieve information related to the user.

I demonstrate this with a very simple & idiotic Sinatra app which actually does nothing intelligent – apart from just outputting first 10 contacts from the user’s address book.

  1. require ‘rubygems’
  2. require ‘sinatra’
  3. require "gdata"
  4.  
  5. client = GData::Client::Contacts.new
  6.  
  7. get "/" do
  8.   next_url = ‘http://127.0.0.1:4567/app’
  9.   secure = false
  10.   session = true
  11.   authsub_link = client.authsub_url(next_url, secure, session, nil)
  12.   redirect(authsub_link)
  13. end
  14.  
  15. get ‘/app’ do
  16.   pp request.env
  17.   client.authsub_token = request.env["rack.request.query_hash"]["token"]
  18.   client.authsub_token = client.auth_handler.upgrade()
  19.   contacts = client.get("http://www.google.com/m8/feeds/contacts/default/full?max-results=5").to_xml
  20.   puts contacts
  21. end

More information about using GData is available at http://code.google.com/apis/gdata/articles/gdata_on_rails.html

Example scenarios this can be used?

  • Allowing people to login into your app with their existing google account.
  • Accessing user data with user’s permission
  • Signing up for your app using Google account information

Happy Hacking!

Courtesy – yet again, Ruby!

  1. #!/usr/bin/env ruby

  4. require "mechanize"
  5.  
  6. module SMS
  7.  
  8.   class OneSixtyByTwo
  9.     attr_accessor :agent, :uid
  10.     attr_accessor :urls
  11.  
  12.     def initialize(username, password)
  13.       @urls = {
  14.         :login => "http://m.160by2.com",
  15.         :sms => "http://m.160by2.com/SaveCompose.asp?l=1"
  16.       }
  17.       @agent = WWW::Mechanize.new
  18.       login = agent.get(@urls[:login])
  19.       login.forms[0].txtUserName = username
  20.       login.forms[0].txtPasswd = password
  21.       page = login.forms[0].submit
  22.       @uid = page.forms[0].action.split("=")[-1].split("&")[0]
  23.     end
  24.  
  25.     def sms(recepient, message)
  26.       message.gsub!(" ", "+")
  27.       params = {
  28.         "Msg" => @uid,
  29.         "TID" => "",
  30.         "T_MsgId" => "",
  31.         "categoryid" => "28:GoodMorning",
  32.         "cmdSend" => "Send+SMS",
  33.         "txt_mobileno" => recepient,
  34.         "txt_msg" =>  message
  35.       }
  36.  
  37.       page = agent.post(@urls[:sms], params)
  38.       if page.code == "200"
  39.         return true
  40.       else
  41.         return false
  42.       end
  43.     end
  44.   end
  45.  
  46. end
  47.  
  48. mobile = "XXXXXXXXXX"
  49. result = SMS::OneSixtyByTwo.new("your_160by2_username", "your_160by2_password").sms(mobile, "Test message")
  50. if result == true
  51.   puts "SMS sent to #{mobile}"
  52. else
  53.   puts "Error in sending the SMS"
  54. end

Result…

[makuchaku@Warrior ruby]$ ./160by2.rb
