如何通过facebook社交插件获取已注册我网站的用户的个人资料图片

Question

I have a registration plugin embeded via an iframe on my website, The registration plugin works fine , I am also able to get the unique user_id of each user by using the following line of code in the signed_request file which can be located here

The line of code i use to get the user_id is: $response["user_id"];

Now that i have a unique id of each user, i want a way by which i can get the link to the profile image of that user, i know i can get the thumbnail of the profile picutre using open graph,

But i am looking for a way by which i can get the link to the complete or the original profile picture, not the thumbnail.

Is there a way this can be done? Using open graph or something like that?

Answer 1

You need user_photos permissions first. Then something like this should do it:

SELECT cover_object_id FROM album WHERE owner=me() and type='profile'

Substitute me() with the user you are querying for.

It returns the photo object that you can then use to pull the full version from.

Answer 2

使用相同signed_request中的access_token对/user_id/?fields=picture进行API调用
