get profile picture from google plus - django

Question

I have used google app engine with django application. I have been using the user api from google to login in my website and also getting the current user email address from that, but i have to get profile picture which is uploded on the google plus account.
I am getting their profile picture using,
<img src="https://plus.google.com/s2/photos/profile/<user_id>?sz=100" width="100" height="100">
in google api.
User class also provides user_id but I cannot get their profile picture using that user_id.
<user_id> and user_id of user class of Google API is different.
How to get the profile picture in my application?

Answer 1

The way to do it is to use the google+ api here: https://developers.google.com/apis-explorer/#p/plus/v1/plus.people.get?userId=me&_h=2&
This is the request to pull the image for the currently authenticated user.
GET https://www.googleapis.com/plus/v1/people/me?key={YOUR_API_KEY}
You'll get a json response like this and it's really easy to parse that and pull out the image->url value to display.

If you are asking the about the ids...
My GoogleID according to user_id() is xxx8005350796570706xx and my Google Plus profile ID is 102445631084043565507 which are totally different
You need to ask the user for his G+ profile or authenticate him via oAth2.0 to get permissions to read his profile.
Also if you have his email address you could use GAvatar.
