Python Social Auth get Google avatar

Question

Is there a way to get the Google profile picture url using python social auth?

So, this is what I do for facebook and twitter, add a pipeline with this code:

    if strategy.backend.name == 'facebook':
        url = 'http://graph.facebook.com/{0}/picture'.format(response['id'])

    elif strategy.backend.name == "twitter":
        if response['profile_image_url'] != '':
            url = response['profile_image_url']

    elif strategy.backend.name == "GoogleOAuth2":  # doesn't work
        user_id = response['id']
        url = "???"

First, I don't know what is the name of the backend, is it "GoogleOAuth2"? Second, what is the url I should use to save the profile's avatar?. Is this the way?

from social.backends.google import GoogleOAuth2

def save_profile(backend, user, response, *args, **kwargs):
    if isinstance(backend, GoogleOAuth2):
        if response.get('image') and response['image'].get('url'):
            url = response['image'].get('url')
            ext = url.split('.')[-1]
            user.avatar.save(
               '{0}.{1}'.format('avatar', ext),
               ContentFile(urllib2.urlopen(url).read()),
               save=False
            )
            user.save()

Thanks vero4ka. I didn't want to save the image, only the url so url_50 = response['image'].get('url') did the trick. Hope that google doesn't change the url format anytime soon. – Haematocryal

To get avatars from social login, you need create a pipeline.py file in your app and add this lines to settings.py:

SOCIAL_AUTH_PIPELINE = (

    'social.pipeline.social_auth.social_details',
    'social.pipeline.social_auth.social_uid',
    'social.pipeline.social_auth.auth_allowed',
    'social.pipeline.social_auth.social_user',
    'social.pipeline.user.get_username',
    'social.pipeline.user.create_user',
    'social.pipeline.social_auth.associate_user',
    'social.pipeline.social_auth.load_extra_data',
    'social.pipeline.user.user_details',
    'apps.users.pipeline.get_avatar', # This is a path of your pipeline.py
    #and get_avatar is the function.
)

and later add this content to your pipeline.py file

def get_avatar(backend, strategy, details, response,
        user=None, *args, **kwargs):
    url = None
    if backend.name == 'facebook':
        url = "http://graph.facebook.com/%s/picture?type=large"%response['id']
        # if you need a square picture from fb, this line help you
        url = "http://graph.facebook.com/%s/picture?width=150&height=150"%response['id']
    if backend.name == 'twitter':
        url = response.get('profile_image_url', '').replace('_normal','')
    if backend.name == 'google-oauth2':
        url = response['image'].get('url')
        ext = url.split('.')[-1]
    if url:
        user.avatar = url
        user.save()

Welcome to SO. If you don't mind, you should add an explanation to your code. Or comment it at least. You might check this meta question on code-only answers – Burr

I'm not familiar with Python Social Auth but it looks like you want GooglePlusAuth.

To get the image url you will have to make a HTTP request to the people.get API method with userId set to me and authenticated as the user. The response includes an image.url value.

I'm using the approach suggested by vero4ka.

Dropping into a python debug (import pdb; pdb.set_trace()) around the line ext = url.split('.')[-1], I notice that the split output doesn't fully separate the file extension viz:

(Pdb) url = response['image'].get('url').split('.')
(Pdb) url
[u'https://lh4', u'googleusercontent', u'com/redacted/redacted/photo', u'jpg?sz=50']

I'll need to split off on the ? symbol too. No big deal.

Not sure why one would split and then recombine the extension in this way?
