Android：Facebook PublishPermissions无需重新输入密码（使用SUPPRESS_SSO时）？

Question

行动在这个Android应用程序的流量 -

1. 用户X在Facebook上注册
2. 用户X授予read_permissions
3. 用户X补助publish_permissions
4. 他是的access_token存储在我们的数据库。

5. 用户X注销

6. UserY登记...因为它需要我需要SUPPRESS_SSO（感谢How to disable Single SIgn On for facebook android app?）多个用户的登录[遵循相同的步骤]

。

现在在Facebook API 3.0中，Facebook使ReadPermissions和PublishPermissions不同。 我成功地要求两个权限，但它需要用户登录两次（因为SSO被抑制并且webview被显示） - 登录webview再次弹出 - 用户必须输入他的电子邮件和密码。 我想访问PublishPermissions或ReadPermissions（以任意顺序），而用户不必重新输入他的密码。

从Java代码相关的功能如下所示：

private static final List<String> PERMISSIONS = Arrays.asList("user_photos", "read_friendlists", "email", "publish_actions", "publish_stream"); 


private void updateView() { 
    Session session = Session.getActiveSession(); 
    if (session.isOpened()) { 
     handleAnnounce(); 
     textInstructionsOrLink.setText(ACKNOWLEDGE_USER); 
     buttonLoginLogout.setText(R.string.logout); 
     buttonLoginLogout.setOnClickListener(new OnClickListener() { 
      public void onClick(View view) { 
       onClickLogout(); 
      } 
     }); 
    } else { 
     textInstructionsOrLink.setText(R.string.login); 
     buttonLoginLogout.setText(R.string.login); 
     buttonLoginLogout.setOnClickListener(new OnClickListener() { 
      public void onClick(View view) { 
       onClickLogin(); 
      } 
     }); 
    } 
} 

private void onClickLogin() { 
    Session session = Session.getActiveSession(); 
    if (!session.isOpened() && !session.isClosed()) { 
     Session.OpenRequest openRequest = new Session.OpenRequest(this).setCallback(statusCallback); 
     List<String> readPermissions = Arrays.asList("user_photos", "email", "read_friendlists"); 
     openRequest.setPermissions(readPermissions); 
     openRequest.setLoginBehavior(SessionLoginBehavior.SUPPRESS_SSO); 
     session.openForRead(openRequest); 
    } else { 
     Session.openActiveSession(this, true, statusCallback); 
    } 
} 


private void requestPublishPermissions(Session session) { 
    Log.d(LOG_TAG, "Requesting Publish Permissions..."); 
    if (session != null) { 
     List<String> publishPermissions = Arrays.asList("publish_actions", "publish_stream"); 
     final int REAUTH_ACTIVITY_CODE = 100; 
     Session.NewPermissionsRequest reauthRequest = new Session.NewPermissionsRequest(this, publishPermissions).setRequestCode(REAUTH_ACTIVITY_CODE); 
     reauthRequest.setLoginBehavior(SessionLoginBehavior.SUPPRESS_SSO); 
     session.requestNewPublishPermissions(reauthRequest); 
    } 
} 

private void handleAnnounce() { 
    Session session = Session.getActiveSession(); 
    if (session == null || !session.isOpened()) { 
     return; 
    } 

    List<String> permissions = session.getPermissions(); 
    if (!permissions.containsAll(PERMISSIONS)) { 
     requestPublishPermissions(session); 
     return; 
    } 
}

你的代码似乎要被罚款，这是最近报道的API的bug：

只是耐心，我我们得到了同样的错误，我们所能做的就是等待一个固定的API。
