Installation

Installing Requests-Facebook is simple:

$ pip install requests-facebook

Usage

Authorization URL

f = FacebookAPI(client_id='*your app key*',
                client_secret='*your app secret*',
                redirect_uri='http://example.com/callback/')

f = FacebookAPI('*your app key*', '*your app secret*', 'http://example.com/callback/')

auth_url = f.get_auth_url(scope=['publish_stream', 'user_photos', 'user_status'])

print 'Connect with Facebook via: %s' % auth_url

Once you click "Allow" be sure that there is a URL set up to handle getting finalized access_token and possibly adding it to your database to access their information at a later date.

Handling the Callback

# Assume you are using the FacebookAPI object from the Authorization URL code

# You'll need to obtain `code` from the url query string

# In Django, you'd do something like
# code = request.GET.get('code')

access_token = f.get_access_token(code)

final_access_token = access_token['access_token']

# Save that token to the database for a later use?

Dynamic Facebook methods

Say you have the url https://graph.facebook.com/me/friends To make a call via this library, you'd do GraphAPI.get('me/friends')

You just take everything in the url AFTER https://graph.facebook.com/

Getting some User information

# Get the final tokens from the database or wherever you have them stored

graph = GraphAPI(access_token)

# Print out your information
try:
    print graph.get('me')
except FacebookClientError:
    print 'Failed! :('

# Print out my information
print graph.get('mikehimself')

Getting your Home Feed

# Assume you are using the GraphAPI instance from the previous section
home_feed = graph.get('me/home')
print home_feed

Getting a Profile Feed

# Assume you are using the GraphAPI instance from the previous section
your_feed = graph.get('me/feed')
print your_feed

# Getting my profile feed
my_feed = graph.get('mikehimself/feed')
print my_feed

Creating a Photo Album

# Assume you are using the GraphAPI instance from the previous section
new_album = graph.post('me/albums', params={'name':'Test Album'})
print new_album

Posting a Photo

# Assume you are using the GraphAPI instance from the previous section
# Assume you are using the album you just created in the previous section

# new_album = new_album var from the previous section
album_id = new_album['id']

photo = open('path/to/file/image.jpg', 'rb')

# The file key that Facebook expects is 'source', so 'source' will be apart
# of the params dict.

# You can pass any object that has a read() function (like a StringIO object)
# In case you wanted to resize it first or something!

new_photo = graph.post('%s/photos' % album_id, params={'message':'My photo caption!', 'source': photo})

print new_photo

Posting an Edited Photo (This example resizes a photo)

# Assume you are using the GraphAPI instance from the previous section
# Assume you are using the album you just created in the previous sections

# Like I said in the previous section, you can pass any object that has a
# read() method

# Assume you are working with a JPEG

from PIL import Image
from StringIO import StringIO

photo = Image.open('/path/to/file/image.jpg')

basewidth = 320
wpercent = (basewidth / float(photo.size[0]))
height = int((float(photo.size[1]) * float(wpercent)))
photo = photo.resize((basewidth, height), Image.ANTIALIAS)

image_io = StringIO.StringIO()
photo.save(image_io, format='JPEG')

image_io.seek(0)

try:
    new_photo = graph.post('%s/photos' % album_id, params={'message':'My photo caption!', 'source': photo})
except FacebookClientError, e:
    # Maybe the file was invalid?
    print e.message

Catching errors (In case you didn't catch it in the first example)

# Assume you are using the GraphAPI instance from the previous section

try:
    graph.delete('me/feed')
except FacebookClientError, e:
    print e.message
    print 'Something bad happened :('
