Question

我正在使用ASP.NET MVC3和Facebook C＃SDK 4.2.1

如果我用CanvasAuthorize装饰一个至少有一个perrmission的控制器或动作，一切都很好。但是，如果我没有传递任何权限或传递空权限字符串，我会收到以下错误：

[FacebookOAuthException: (OAuthException) Error validating access token.]

这是我做错了什么，还是SDK的问题？

我遇到了与此类似的问题，所以不确定它是否与您的问题有关，但我的是fbs_APPID cookie不再有效但仍尝试从中拉出access_token。

（OAuthException）在没有权限的情况下使用CanvasAuthorize时，验证访问令牌时出错
