authentication - 除非删除 cookie，否则 ServiceStack AuthenticateAttribute 第二次导致空引用异常

Question

我正在尝试让 ServiceStacks 身份验证在 MVC 站点上工作。我的控制器是这样的：

  public abstract class ControllerBase : ServiceStackController<AuthUserSession> {
    //TODO: override LoginRedirectUrl  
  }

  public class IndexController : ControllerBase {
    [Authenticate]
    public ActionResult Index() {
      return View();
    }
  }

我第一次通过从 Visual Studio 启动站点来测试代码时，会重定向到 /login 路由。

现在，如果我从 Visual Studio 再次启动该站点，则会引发如下所示的空引用异常，并且在每次重新启动时都会发生这种情况，直到我删除浏览器中的所有 cookie。

看起来像一个错误？

好的不要紧。我遇到的错误可能是因为我还没有实现登录路由。
