Facebook Graph with Ruby

Category: Facebook,Ruby

The Open Graph protocol enables developers to integrate their pages into the social graph. These pages gain the functionality of other graph objects including profile links and stream updates for connected users. Documentations for facebook api are available on this link.
Ruby offer a library to communicate with Facebook Graph named “rfgraph”.
To install :

  1. $ sudo gem install rfgraph

Next, you can write your code. We will use this library to retrieve user information for a range of id. For this, we will create a loop from 610552189 ( my id) to 610552219 (another id) and show available information :

  1. require ‘rubygems’
  2. require ‘rfgraph’
  3.  
  4. req = RFGraph::Request.new
  5.  
  6. for i in 610552189..610552219 do
  7.   begin
  8.     res= req.get_object(i)
  9.     puts "#{res[‘id’]} #{res[‘name’]} #{res[‘first_name’]} #{res[‘last_name’]}"+
  10.       " #{res[‘gender’]} #{res[‘locale’]} #{res[‘link’]}"
  11.   rescue Exception=>e
  12.   end
  13. end

and the result will be :
