获取电子邮件，GraphUser与权限 [英] Getting email from GraphUser with Permissions

问题描述

我在尝试登录与下面的code FB。该GraphUser对象有姓，名，ID，但不是电子邮件。我知道我需要添加权限，但我怎么做，在这种情况下。权限一般都加入 Session.OpenRequest 或LogInButton，但我不使用这些。有什么建议？

  Session.openActiveSession（活动，真，新Session.StatusCallback（）{
        //回调时，会话状态变化
        @覆盖
        公共无效电话（最后一届会议，SessionState会状态，异常除外）{
            如果（session.isOpened（））{
                //使请求/我API                Request.newMeRequest（会话，新Request.GraphUserCallback（）{
                    //后用户对象图形API响应回调
                    @覆盖
                    公共无效onCompleted（GraphUser用户，响应响应）{
                        如果（用户！= NULL）{
                            //从GraphUser收到电子邮件
                        }
                    }
                }）executeAsync（）。
            }
        }
    }）;
 

解决方案

只需添加权限作为参数 openActiveSession ：

  Session.openActiveSession（活动，真实，Arrays.asList（public_profile，电子邮件），新Session.StatusCallback（）{
    //回调时，会话状态变化
    @覆盖
    公共无效电话（最后一届会议，SessionState会状态，异常除外）{
        如果（session.isOpened（））{
            //使请求/我API            Request.newMeRequest（会话，新Request.GraphUserCallback（）{
                //后用户对象图形API响应回调
                @覆盖
                公共无效onCompleted（GraphUser用户，响应响应）{
                    如果（用户！= NULL）{
                        //从GraphUser收到电子邮件
                    }
                }
            }）executeAsync（）。
        }
    }
}）;
 

I'm attempting a log-in with FB with the code below. The GraphUser object has first name, last name, ID, but not email. I know I need to add permissions but how do I do it in this case. The permissions are generally added with Session.OpenRequest or the LogInButton but I'm not using those. Any suggestions?

Session.openActiveSession(activity, true, new Session.StatusCallback() {
        // callback when session changes state
        @Override
        public void call(final Session session, SessionState state, Exception exception) {
            if (session.isOpened()) {
                // make request to the /me API

                Request.newMeRequest(session, new Request.GraphUserCallback() {
                    // callback after Graph API response with user object
                    @Override
                    public void onCompleted(GraphUser user, Response response) {
                        if (user != null) {
                            // get email from GraphUser
                        }
                    }
                }).executeAsync();
            }
        }
    });

解决方案

Just add the permissions as a parameter in openActiveSession:

Session.openActiveSession(activity, true, Arrays.asList("public_profile", "email"), new Session.StatusCallback() {
    // callback when session changes state
    @Override
    public void call(final Session session, SessionState state, Exception exception) {
        if (session.isOpened()) {
            // make request to the /me API

            Request.newMeRequest(session, new Request.GraphUserCallback() {
                // callback after Graph API response with user object
                @Override
                public void onCompleted(GraphUser user, Response response) {
                    if (user != null) {
                        // get email from GraphUser
                    }
                }
            }).executeAsync();
        }
    }
});
