Facebook共同好友API

Question

Using the Facebook Graph API (v2.4), I can't seem to access any information about mutual friends, not even the total count.

Here's my graph query (User ID changed for privacy purposes): https://graph.facebook.com/v2.4/123456789?fields=context.fields(mutual_friends)

The result I get is:

 { "context": { "id": "dXNlcl9jb250ZAXh0OgGQBqWf9ZAHMZA1yjZBJZABsMDkDORNsle8wkS8Acci9r4FsOdyRVl1TSGSXAsofmlaWYS05piSZCV9F1QwNNs0L9XpNuGLAaLyMk8Fnaiwyxpm5shUZD" }, "id": "123456789" } 

I tried using FB's iOS SDK to make the same query as well, but got the same result.

Any suggestions?

Answer 1

The all_mutual_friends , mutual_friends , and three_degree_mutual_friends context edges of the Social Context API were deprecated on April 4, 2018 and immediately started returning empty data sets. They have now been fully removed.

Answer 2

The {user_id} must be another user of your app, and the user access token you MUST use is from another user of your app.

Then

GET /{user_id}?fields=context{mutual_friends}&access_token={other_users_access_token}

should work and give results, if both users gave your app the user_friends permission.
