Android的 - Facebook的GraphUser没有email属性 [英] Android - Facebook GraphUser has no email attribute

问题描述

我检查，并仔细检查有关问题的在线资源 - 但我仍然无法从Facebook的回应email属性。

作为入门指示，我实现了对LoginButton（basic_auth，电子邮件，user_birthday）的读取权限。创建一个会话（Session.createFromExistingAccessToken）时，也设置了相同的权限。然而，在回调函数，记录GraphUser和Response对象的时候，我还是没能获取用户的电子邮件。

什么是为什么错误仍坚持可能的原因是什么？我错过了一些步骤？

  **的onCreate（）**    （（LoginButton）findViewById（R.id.dialog_generic_footer_button_fblogin））
                .setPublishPermissions（FBSessionV2.getPermissions（））;
 

的Facebook会话类

  ...
    公共静态的ArrayList＆LT;串GT; getPermissions（）{
       如果（PERMISSIONS.isEmpty（））{
        PERMISSIONS.add（basic_info）;
        PERMISSIONS.add（电子邮件）;
        PERMISSIONS.add（publish_actions）;
        PERMISSIONS.add（user_birthday）;
       }
       返回的权限;
    }
...
 

WebDialog.onCompleteListener

 会议= Session.getActiveSession（）;如果（session.isOpened（）及！＆放大器;！session.isClosed（））{
    Logger.log（Thread.currentThread（）的getStackTrace（），称的accessToken+值，Log.DEBUG）;
    在= AccessToken.createFromExistingAccessToken（values​​.getString（的access_token），NULL，NULL，AccessTokenSource.WEB_VIEW，FBSessionV2.getPermissions（））的accessToken;
    会话= Session.openActiveSessionWithAccessToken（ControllerBase.getInstance（）getActivity（），在，CB）;
}其他{
    Logger.log（Thread.currentThread（）的getStackTrace（），称openactivesession，Log.DEBUG）;
    Session.openActiveSession（ControllerBase.getInstance（）getActivity（），真实，CB）;
}
 

GraphUserCallback（）

  ...
    userProfile.put（facebookId，user.getId（））;
    userProfile.put（电子邮件，user.getProperty（电子邮件））;
    userProfile.put（如first_name，user.getFirstName（））;
    userProfile.put（姓氏，user.getLastName（））;
    userProfile.put（名，user.getName（））;
    userProfile.put（性别，user.getProperty（性别））;

更新

好像我们只是遇到问题时，我们的Facebook应用程序试图登录Facebook账户，是不是一个开发商（可能还有是管理员）。我们只是试图登录在具有开发者角色我们FB账号之一 - 并且取得了成功。

不过，由于应用程序将供市民使用作出，这仍然没有解决我们的问题（可能也被视为创可贴修复现在 - 我还需要进一步调查该问题）

解决方案

也许你的应用程序在沙盒模式。请看看这里：

https://developers.facebook.com/docs/ApplicationSecurity/#sandbox

它说

  

请注意，如果您的应用程序在沙盒模式下，你不能调用任何
  API调用代表用户谁也看不到你的应用程序。

I've checked and double-checked online sources regarding the issue - but I still can't get the email attribute from the Facebook Response.

As indicated on the Getting Started, I implemented the read permissions ("basic_auth", "email", "user_birthday") on the LoginButton. Also set the same permissions when creating a session (Session.createFromExistingAccessToken). However, on the callback function, when Logging the GraphUser and Response object, I still wasn't able to retrieve the email of the user.

What are the possible reasons on why the error is still persisting? Am I missing some steps?

**onCreate()**

    ((LoginButton) findViewById(R.id.dialog_generic_footer_button_fblogin))
                .setPublishPermissions(FBSessionV2.getPermissions());

Facebook session class

...
    public static ArrayList<String> getPermissions(){
       if (PERMISSIONS.isEmpty()){
        PERMISSIONS.add("basic_info");
        PERMISSIONS.add("email");
        PERMISSIONS.add("publish_actions");
        PERMISSIONS.add("user_birthday");
       }
       return PERMISSIONS;
    }
...

WebDialog.onCompleteListener

session = Session.getActiveSession();

if (!session.isOpened() && !session.isClosed()){
    Logger.log(Thread.currentThread().getStackTrace(), "calling accesstoken" + values, Log.DEBUG);
    AccessToken at = AccessToken.createFromExistingAccessToken(values.getString("access_token"), null, null, AccessTokenSource.WEB_VIEW, FBSessionV2.getPermissions());
    session = Session.openActiveSessionWithAccessToken(ControllerBase.getInstance().getActivity(), at, cb);
} else {
    Logger.log(Thread.currentThread().getStackTrace(), "calling openactivesession", Log.DEBUG);
    Session.openActiveSession(ControllerBase.getInstance().getActivity(), true, cb);
}

GraphUserCallback()

...
    userProfile.put("facebookId", user.getId());
    userProfile.put("email", user.getProperty("email"));
    userProfile.put("first_name", user.getFirstName());
    userProfile.put("last_name", user.getLastName());
    userProfile.put("name", user.getName());
    userProfile.put("gender", user.getProperty("gender"));
    userProfile.put("birthday", user.getBirthday());
    if (user.getProperty("email") != null){
        userProfile.put("email", (String) user.getProperty("email"));
    }
...

UPDATE

It seems we're only having trouble when we're trying to log-in a Facebook account that is not a Developer (and may as well be Administrator) of the Facebook app. We just tried to log-in one of our FB account that has a Developer role - and it succeeds.

However, since the app will be made for public use, this still doesn't solve our problem (may as well be treated as a band-aid fix for now - I still need to further investigate the issue).

解决方案

Probably your app is in sandbox mode. Please have a look here:

https://developers.facebook.com/docs/ApplicationSecurity/#sandbox

It's saying

Please note that when your app is in Sandbox Mode, you cannot call any API calls on behalf of users who cannot see your app.
