Facebook graph api Facebook在main.lua上获取用户信息，但在应用程序内部调用时却无处获取

我正在尝试在我的应用程序中获取facebook的用户id和名称。当我尝试在不同的屏幕上登录facebook时，出现了一个不明错误。 当我从main.lua文件调用facebook登录屏幕时，我成功地在iOS simulator的调试器中获取用户名和id，如下所示，以及一些关于不影响登录的错误的更多信息

版本：3.0.0

建造日期：2015.2731

iOS模拟器9.1（13B137）

这意味着facebook登录成功，但当我点击“获取用户信息”按钮时，我得到了这个信息

直到昨天，我还收到了这两个错误，你现在可以在上面facebook用户信息工作的第一段代码中看到，所以我不确定这是否是真正的问题。 侦听器连接收到的正常消息。忽略。 初始化期间无法成功更新网络信息。 因为我使用的是Corona的facebook示例应用程序，所以它应该很容易为任何人复制。。只需将所有main.lua代码移动到另一个场景，并点击按钮调用该场景

这是我的facebook_login.lua文件，与corona的facebook示例应用程序差别不大
