1. fIntroduction to Facebook PY API Introduction to Facebook Python API Social Network and Applications, 2011 LittleQ, The Department of Computer Science, NCCU
2. fIntroduction to Facebook PY API Objectives • Learn the concepts of Facebook API • Learn how to play with Facebook Graph API
3. fIntroduction to Facebook PY API Core Topics • Facebook Developers website • Graph API • Facebook Python SDK • Resources
4. fIntroduction to Facebook PY API Facebook Developers • Provide you online documentations • Forum for discussion • Management of your applications
5. fIntroduction to Facebook PY API Where is it?
6. fIntroduction to Facebook PY API Social Plugins • Like Button, Send Button, Login Button • Comments • Your Friends • Activity Feed, Live Stream
7. fIntroduction to Facebook PY API Is That What You Want?
8. fIntroduction to Facebook PY API Graph API • Facebook’s core • Social graph • Connections Application Graph API Facebook Database Access Token Request Data Aggregate Information Response Data
9. fIntroduction to Facebook PY API Graph Model • Composed of objects and connections • Identify entities and relationships by id • Data will be stored with smallest spaces and keep being updated
10. fIntroduction to Facebook PY API Object Model information from graph API without access token
11. fIntroduction to Facebook PY API Graph Model information from graph API with access token
12. fIntroduction to Facebook PY API 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
13. fIntroduction to Facebook PY API Connection Model
14. fIntroduction to Facebook PY API Access to Graph • HTTP(S) Graph API • SDKs ‣ Javascript SDK ‣ iOS SDK ‣ Android SDK ‣ PHP SDK ‣ Python SDK
15. fIntroduction to Facebook PY API HTTP(S) Graph API • RESTful HTTP request & response • Response data-type: JSON • Access URL: graph.facebook.com
16. fIntroduction to Facebook PY API HTTP(S) Graph API • Request information of an object with id or username • id-or-username can be “me” with the access token http://graph.facebook.com/<id-­‐or-­‐username>
17. fIntroduction to Facebook PY API HTTP(S) Graph API {      "id":  "1681390745",      "name":  "Colin  Su",      "first_name":  "Colin",      "last_name":  "Su",      "link":  "https://www.facebook.com/littleq0903",      "username":  "littleq0903",      "gender":  "male",      "locale":  "en_US" } http://graph.facebook.com/littleq0903 Result:
18. fIntroduction to Facebook PY API 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
19. fIntroduction to Facebook PY API 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
20. fIntroduction to Facebook PY API HTTP(S) Graph API • Access token should be transferred as a HTTP GET variable • More information: developers.facebook.com/docs/reference/ api/ http://graph.facebook.com/littleq0903?access_token=...
21. fIntroduction to Facebook PY API Python SDK • Let you access all features of the Graph API • That’s all, let’s play!
22. fIntroduction to Facebook PY API Python SDK • https://github.com/facebook/python-sdk • Designed to support Graph API and FB Javascript SDK (You will learn in the future)
23. fIntroduction to Facebook PY API Graph • Depends your access token • Everyone will have their own graph, could be unique
24. fIntroduction to Facebook PY API Graph API Class • Fetch the graph by implement it import  facebook graph  =  facebook.GraphAPI() user  =  graph.get_object(“littleq0903”)
25. fIntroduction to Facebook PY API Authentication • Graph can be implemented with an access token • And the perspective of the graph will be different my_profile  =  graph.get_object(“me”) graph  =  GraphAPI(ACCESS_TOKEN)
26. fIntroduction to Facebook PY API Graph Methods • get_object, get_objects • get_connections • put_object • put_wall_post, put_comment, put_like • delete_object
27. fIntroduction to Facebook PY API Demo
28. fIntroduction to Facebook PY API Homework • Fetch a kind of data on the FB Graph • Do some statistics on it • Don’t Copy from others
29. fIntroduction to Facebook PY API Q&A Time Thanks for your listening
