* http://rdoc.info/projects/cardinalblue/rest-graph

== 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/',
:fql_server => '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=...
rg.get('4/likes') # GET https://graph.facebook.com/4/likes?access_token=...

# GET https://graph.facebook.com/search?q=...&access_token=...
rg.get('search', :q => 'taiwan')

# GET https://graph.facebook.com/me?metadata=1&access_token=...
rg.get('me', :metadata => '1')

# POST https://graph.facebook.com/feed/me?m...&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=
# 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/aut...client_id=...&
RestGraph.new.authorize_url(:redirect_uri => '...')

# get access token by:
# 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
