        }

        @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {
                mFacebook.authorizeCallback(requestCode, resultCode, data);
        }
}

作为响应，我得到一个 JSON。示例:

08-15 14:22:42.160: DEBUG/FACEBOOK(1258): Response: {"id":"3159628280","name":"Peter Black","first_name":"Peter","last_name":"Black","link":"http:\/\/www.facebook.com\/Peter.Black","username":"Peter.Black","gender":"male","timezone":3,"locale":"bg_BG","verified":true,"updated_time":"2011-08-14T08:42:59+0000"}

我的问题是如何获取用户的电子邮件(他登录 Facebook 所用的电子邮件)？

Answer 1

您需要email 权限才能读取用户的电子邮件地址。这将在来自 [uid] 或 me 请求的 json 响应中添加一个电子邮件标记。

电子邮件

Provides access to the user's primary email address in the email property. Do not spam users. Your use of email must comply both with Facebook policies and with the CAN-SPAM Act.
