== DESCRIPTION:

A super simple Facebook Open Graph API client

== FEATURES:

- Simple graph api call
- Simple fql call
- Utility to extract access\_token and check sig in cookies

== CHANGES in 1.1.1

- Add oauth realted utilites – authorize\_url and authorize!
- Fixed a bug that in Ruby 1.8.7-, nil =~ /regexp/ equals to false.  
It is nil as expected in Ruby 1.9.1+

== SYNOPSIS:

require ‘rest-graph’

# every option is optional!!

rg = RestGraph.new(:access\_token =\> ‘…’,  
:graph\_server =\> ‘[https://graph.facebook.com/](https://graph.facebook.com/)’,  
:fql\_server =\> ‘[https://api.facebook.com/](https://api.facebook.com/)’,  
:accept =\> ‘text/javascript’,  
:lang =\> ‘en-us’, # this affect search  
:auto\_decode =\> true, # decode by json  
:app\_id =\> ‘123’,  
:secret =\> ‘1829’)

rg.get(‘me’) # GET [https://graph.facebook.com/me?access\_token=](https://graph.facebook.com/me?access_token=)…  
rg.get(‘4/likes’) # GET  
[https://graph.facebook.com/4/likes?access\_token=](https://graph.facebook.com/4/likes?access_token=)…

# GET [https://graph.facebook.com/search?q=taiwan&access\_token=](https://graph.facebook.com/search?q=taiwan&access_token=)…

rg.get(‘search’, :q =\> ‘taiwan’)

# GET [https://graph.facebook.com/me?metadata=1&access\_token=](https://graph.facebook.com/me?metadata=1&access_token=)…

rg.get(‘me’, :metadata =\> ‘1’)

# POST

[https://graph.facebook.com/feed/me?message=bread!&access\_token=](https://graph.facebook.com/feed/me?message=bread%21&access_token=)…  
rg.post(‘feed/me’, :message =\> ‘bread!’)

# for fully blown cookies hash

rg = RestGraph.new(:app\_id =\> ‘123’, :secret =\> ‘1829’)  
rg.parse\_cookies!(cookies) # auto save access\_token if sig checked  
rg.data[‘uid’] # =\> facebook uid

# fql query, same as:

# GET [https://api.facebook.com/method/fql.query?query=](https://api.facebook.com/method/fql.query?query=)

# SELECT+name+FROM+page+WHERE+page\_id%3D%22123%22&

# format=json&access\_token=…

rg.fql(‘SELECT name FROM page WHERE page\_id=“123”’)

# default setting:

class RestGraph  
def self.default\_app\_id  
‘456’  
end

def self.default\_secret  
‘category theory’  
end  
end

# auto load config

require ‘rest-graph’  
require ‘rest-graph/auto\_load’ # under Rails, load config/rest-  
graph.yaml  
RestGraph.new # all default options would honor  
config  
RestGraph.new(:app\_id =\> ‘123’) # default could be override as well

# manually load config

require ‘rest-graph/load\_config’  
RestGraph::LoadConfig.load\_config!(‘path/to/rest-graph.yaml’, ‘env’)

# see test/config/rest-graph.yaml for an example for config

# oauth utilites:

# [https://graph.facebook.com/oauth/authorize?client\_id=...&](https://graph.facebook.com/oauth/authorize?client_id=...&)

RestGraph.new.authorize\_url(:redirect\_uri =\> ‘…’)

# get access token by:

# [https://graph.facebook.com/oauth/access\_token?code=...&](https://graph.facebook.com/oauth/access_token?code=...&)

rg = RestGraph.new  
rg.authorize!(:redirect\_uri =\> ‘…’, :code =\> ‘zzz’)  
rg.access\_token # your access\_token is now available  
rg.data[‘expires’] # other values as well
