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.

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

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

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

20. HTTP(S) Graph API
• Access token should be transferred as a
HTTP GET variable

23. Graph
• Depends your access token
• Everyone will have their own graph, could
be unique
f

24. Graph API Class
• Fetch the graph by implement it
import
facebook
graph
=
facebook.GraphAPI()
user
=
graph.get_object(“littleq0903”)
f

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
