果园信号器 CryptographicException

Question

我在 Windows Server 2008 上的 IIS 上部署了带有 SignalR 1.3.1 chat module 的 Orchard 出现此异常。它在调试环境中运行良好。

The data protection operation was unsuccessful. This may have been caused by not having the user profile loaded for the current thread's user context, which may be the case when the thread is impersonating.

 Exception Details: System.Security.Cryptography.CryptographicException: The data protection operation was unsuccessful. This may have been caused by not having the user profile loaded for the current thread's user context, which may be the case when the thread is impersonating.

模块有一个bug。

您可以通过在 Load(ContainerBuilder moduleBuilder) 方法行中添加到 CoreModule.cs 来解决此问题：

moduleBuilder.RegisterType<MachineKeyProtectedData>()
  .As<IProtectedData>();
