Deciphering the Interoperable Web
10 likes1,364 views
The document discusses the concept of the interoperable web, highlighting technologies like PubSubHubbub, Webfinger, and Activity Streams. It provides code examples in Ruby for implementing these technologies, showcasing their utility in facilitating communication and data sharing across platforms. Additionally, it touches on OAuth 2.0 for authentication and encourages adoption of standards to minimize complexity and promote interoperability.
![require 'rubygems'
require 'sinatra'
require 'oauth2'
require 'json'
def client
OAuth2::Client.new('app_id', 'app_secret', :site => 'https://
graph.facebook.com')
end
get '/auth/facebook' do
redirect client.web_server.authorize_url(
:redirect_uri => 'http://localhost:4567/auth/facebook/callback',
:scope => 'email,offline_access'
)
end
get '/auth/facebook/callback' do
access_token = client.web_server.get_access_token(
params[:code], :redirect_uri => redirect_uri)
user = JSON.parse(access_token.get('/me'))
user.inspect
end
