我已经将我的网站上传到网站主办,这个错误出现了;
' 在加密操作期间发生错误.'.
我做了一些研究,似乎将经过形式化的cookie绑定到MachineKey(使用webhost时有所不同).
我找到了一个方法来解决这个问题,但错误仍然存在.
码:
/// <summary>
/// This method removes a cookie if the machine key is different than the one that saved the cookie;
/// </summary>
protected void Application_Error(object sender, EventArgs e)
{
var error = Server.GetLastError();
var cryptoEx = error as CryptographicException;
if (cryptoEx != null)
{
FederatedAuthentication.WSFederationAuthenticationModule.SignOut();
Global.Cookies.FormAuthenticated Cookie = new Global.Cookies.FormAuthenticated();
Cookie.Delete();
Server.ClearError();
}
}

据我所知,SessionAuthenticationModule的cookie出了问题.如果您清除cookie(如此处已在Azure上联合身份验证中所述),它可以正常工作.我想要的是了解发生了什么,如何捕捉异常并解决问题.
我收到以下错误.这似乎只是在我升级我的visual studio 2015以进行第一次更新后才开始.我在这里读过一些关于机器密钥问题的线程吗？我不知道如何解决它并防止它.目前,当我使用IIS express在调试中运行时,我在本地计算机上收到此错误.
