In Facebook Graph API, what are the API calls to get a user's email address

问题

Here I'm simply sending a GET request through a rest client.It returns only user id and name .Additionally, how do I retrieve user's email using only a GET request?

https://graph.facebook.com/me?access_token= [User's access token]

回答1:

https://graph.facebook.com/me?fields=name,email&access_token=[User's access token]

It´s called "Declarative Fields" and came with v2.4 of the Graph API: https://developers.facebook.com/docs/apps/changelog#v2_4

API Explorer test: https://developers.facebook.com/tools/explorer/?method=GET&path=me%3Ffields%3Dname%2Cemail

Of course you need to use a User Token that includes the email permission/scope. Debug your Token here: https://developers.facebook.com/tools/debug/accesstoken/

I know this is sort of an old question, but just so anyone else misses it: even if you give permission when generating the token, if the user doesn't have an email registered to his/her facebook account or hasn't confirmed the email yet, facebook won't return it when you query.

You can see this on the Graph API Explorer:

Hope this helps :)
