There are a lot of great Facebook API clients out there and most of them are coded better than this one. Still none worked out for me. Facebooker was bloated (a class for every api call, yikes!), and others were slow to adopt to platform changes. This is my personal client and I use it on several high traffic apps (over 1M dau). The general philosophy is to have a minimal codebase that can adapt to dramatic changes in the Facebook API.
This client is tailored for Heroku in that configuration variables are pulled from the environment.
Set the following variables in the appropriate environment file
ENV['FB_APP_ID'] = "gattaca"
ENV['FB_API_KEY'] = "gattaca"
ENV['FB_SECRET'] = "gattaca"
ENV['FB_CANVAS'] = "gattaca"
ENV['FB_CALLBACK_URL'] = "http://gattaca.heroku.com" # no trailing slash
class Fb < FacebookClient::Base
# custom methods here
end
# initialize client with default configuration
fb = Fb.new
# make a rest api call
fb.rest_api.call 'admin.setAppProperties', :properties => {
:application_name => 'Snowbook',
:callback_url => self.callback_url+'/',
:connect_url => self.callback_url+'/',
:iframe_enable_util => 1,
:use_iframe => 1,
:is_mobile => 1,
:dev_mode => 0,
:privacy_url => self.callback_url+'/privacy.html'
}.to_json
# generate oauth2 authorization url
fb.auth.url(
:scope => User.required_permissions.join(','),
:redirect_uri => redirect_uri,
:display => 'page'
)
# obtain access_token from oauth2 authorization callback
graph = fb.auth.request_access(
:code => params[:code],
:redirect_uri => fb.redirect_uri
)
graph.access_token
# inialization oauth2 session with access token
graph = Fb.new.graph(user.access_token, 0)
graph.get('/me')
