我正在尝试创建一个带有facebook身份验证的登录页面，它运行得很好，但下次我收到这条消息时，消息似乎是来自他们，但即使几个月后也不起作用。这里可能出了什么问题？这是错误的屏幕截图。

我的控制台或任何地方都没有任何错误。当我第一次进行身份验证时，它工作得很好，但下次尝试时，它根本不起作用。
尝试相应地比较和编辑您的代码，或者您可以将其复制到一个新的app.js中并尝试运行它，但请记住事先备份旧的app.js并将其保存到其他地方。你仍然需要在facebook开发者中进行适当的设置来运行它。

将鼠标悬停在包含实时Facebook应用程序的块上，然后单击右上角出现的向下箭头按钮。然后从菜单中选择创建测试应用程序。
创建Facebook测试应用
将使用生产应用程序设置的快照创建测试应用程序。之后，您可以在不影响生产应用程序的情况下独立编辑测试应用程序的设置。
请参阅此处的文档：https://developers.facebook.com/docs/apps/test-apps/
关于设置的其余部分：
让你的应用程序处于开发模式转到"设置"->Basic(左手菜单(并输入"；localhost"；对于应用程序域，将您的网站URL更改为localhost版本(例如。http://localhost:3000/users/auth/facebook)
