This document introduces the Facebook Python API. It discusses the Facebook Developer website, Graph API, and Python SDK. The Graph API allows accessing Facebook data through HTTP requests and responses in JSON format. An access token is required to authenticate requests. The Python SDK facilitates working with the Graph API and retrieving Facebook data and user profiles programmatically. Examples demonstrate using the SDK to fetch object and connection data from the graph.

- 9. Graph Model • Composed of objects and connections • Identify entities and relationships by id • Data will be stored with smallest spaces and keep being updated f Introduction to Facebook PY API
- 10. Object Model information from graph API without access token f Introduction to Facebook PY API
- 11. Graph Model information from graph API with access token f Introduction to Facebook PY API
- 12. Connection Model • All of the object in the Facebook social graph are connected to each other via connections • Objects are just like entities while connections are like relationship • For example, users, pages and groups are objects and likes, friends and feeds are connections f Introduction to Facebook PY API
- 13. Connection Model f Introduction to Facebook PY API
- 14. Access to Graph • HTTP(S) Graph API • SDKs ‣ Javascript SDK ‣ iOS SDK ‣ Android SDK ‣ PHP SDK ‣ Python SDK f Introduction to Facebook PY API
- 15. HTTP(S) Graph API • RESTful HTTP request & response • Response data-type: JSON • Access URL: graph.facebook.com f Introduction to Facebook PY API
- 16. HTTP(S) Graph API http://graph.facebook.com/<id-‐or-‐username> • Request information of an object with id or username • id-or-username can be “me” with the access token f Introduction to Facebook PY API
- 17. HTTP(S) Graph API http://graph.facebook.com/littleq0903 Result: { "id": "1681390745", "name": "Colin Su", "first_name": "Colin", "last_name": "Su", "link": "https://www.facebook.com/littleq0903", "username": "littleq0903", "gender": "male", "locale": "en_US" } f Introduction to Facebook PY API
- 18. Access Token • A long string stands for the authentication of users • Temporary • The information behind the access token ‣ user id ‣ app id ‣ expired time ‣ secret f Introduction to Facebook PY API
- 19. Get Access Token • GetMyAccess http://getmyaccess.heroku.com • It requires a permission called “offline_access”, so this token can be valid for a long time f Introduction to Facebook PY API
- 20. HTTP(S) Graph API • Access token should be transferred as a HTTP GET variable http://graph.facebook.com/littleq0903?access_token=... • More information: developers.facebook.com/docs/reference/ api/ f Introduction to Facebook PY API
- 21. Python SDK • Let you access all features of the Graph API • That’s all, let’s play! f Introduction to Facebook PY API
- 22. Python SDK • https://github.com/facebook/python-sdk • Designed to support Graph API and FB Javascript SDK (You will learn in the future) f Introduction to Facebook PY API
- 23. Graph • Depends your access token • Everyone will have their own graph, could be unique f Introduction to Facebook PY API
- 24. Graph API Class • Fetch the graph by implement it import facebook graph = facebook.GraphAPI() user = graph.get_object(“littleq0903”) f Introduction to Facebook PY API
- 25. Authentication my_profile = graph.get_object(“me”) • Graph can be implemented with an access token graph = GraphAPI(ACCESS_TOKEN) • And the perspective of the graph will be different f Introduction to Facebook PY API
- 26. Graph Methods • get_object, get_objects • get_connections • put_object • put_wall_post, put_comment, put_like • delete_object f Introduction to Facebook PY API
