如何在 GraphRequest.newMeRequest 上获取用户电子邮件 [英] How to get user email on GraphRequest.newMeRequest

问题描述

我的 Android 应用程序中有 Facebook 登录选项，但我尝试获取用户的电子邮件失败.用户登录并添加到 Parse.com 用户表(使用有效的访问令牌)后，我请求 Facebook 用户信息，但只获取它的 ID 和名称(即使电子邮件被设置为权限之一).

I have a Facebook login option in my Android app and I am trying to get the user's email unsuccessfully. After the user is logged in, and added to the Parse.com User table (with a valid access token), I request the Facebook user info, but only get it's id and name (even though the email is set as one of the permissions).

这是我的代码(在我的按钮的 OnClickListener 中):

Here's my code (inside OnClickListener of my button):

ParseFacebookUtils.logInWithReadPermissionsInBackground(
    getActivity(), Arrays.asList("email", "user_friends"), new LogInCallback() {
        @Override
        public void done(ParseUser user, ParseException err) {
            //err is null

            if (user == null) {
                Log.d(TAG, "Uh oh. The user cancelled the Facebook login.");
            } else {
                GraphRequest.newMeRequest(
                    AccessToken.getCurrentAccessToken(),
                    new GraphRequest.GraphJSONObjectCallback() {
                        @Override
                        public void onCompleted(JSONObject user, GraphResponse response) {

                            Log.d(TAG, "user = " + user.toString());
                            //prints -> user = {"name":"my_fb_name","id":"my_fb_id"}
                        }
                    }
                ).executeAsync();                
           }
       });

推荐答案

我猜这与 Graph API v2.4 中的更改有关，这使得您必须指定要从 Graph API 返回的每个字段.

I guess this is related to a change in the Graph API v2.4 which makes it necessary that you specify every field you want to have returned from the Graph API.

• Facebook 仅返回用户的姓名和 ID

有关如何为 GraphRequest

GraphRequest request = GraphRequest.newMeRequest(
        accessToken,
        new GraphRequest.GraphJSONObjectCallback() {
            @Override
            public void onCompleted(
                   JSONObject object,
                   GraphResponse response) {
                // Application code
            }
        });
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email");
request.setParameters(parameters);
request.executeAsync();
