}
});

Answer 1

Since v2.0 of the Graph API, it´s not possible to get friend birthdays anymore. You can only get the birthday of the authorized user by using the user_birthday permission. See the changelog for more information: https://developers.facebook.com/docs/apps/changelog

There is only one other possibility: If the friend authorized the App with user_birthday, you can get his birthday with the following call: /friend-id?fields=birthday

Of course you need to authorize users with user_friends too, in order to make this work. And you can also just store the birthday of all authorized users and don´t waste an extra API call on it. Check This :

Answer 2

更改 user_birthday 的生日和 user_gender 的性别，然后按照https://developers.facebook.com/docs/facebook-login/review上的说明提交应用程序以查看权限
