如何在Global.asax中处理事件SessionSecurityTokenReceived？

Question

我正在尝试在WIF中设置滑动会话,并且需要处理SessionSecurityTokenReceived.

我确定我在这里做了一些愚蠢的事......但是VS2010继续告诉我There is no applicable variable or member在下面说明的地方.谁能指出我正确的方向？我已经搜索了如何定义这个事件的处理的实际样本的高低,但我找不到一个.

Global.asax中

protected void Application_Start()
{

    FederatedAuthentication.WSFederationAuthenticationModule.SecurityTokenReceived 
           += SessionAuthenticationModule_SessionSecurityTokenReceived;
     //         ^^^ There is no applicable variable or member
}



void SessionAuthenticationModule_SessionSecurityTokenReceived(object sender, SessionSecurityTokenReceivedEventArgs e)
{
            DateTime now = DateTime.UtcNow;
            DateTime validFrom = e.SessionToken.ValidFrom;
            DateTime validTo = e.SessionToken.ValidTo;
            if ((now < validTo) &&
            (now > validFrom.AddMinutes((validTo.Minute - validFrom.Minute) / 2))
            )
            {
                SessionAuthenticationModule sam = sender as SessionAuthenticationModule;
                e.SessionToken =  sam.CreateSessionSecurityToken(
                    e.SessionToken.ClaimsPrincipal, 
                    e.SessionToken.Context,
                    now,
                    now.AddMinutes(2), 
                    e.SessionToken.IsPersistent);
                e.ReissueCookie = true;
            }
            else
            {
                //todo: WSFederationHelper.Instance.PassiveSignOutWhenExpired(e.SessionToken, this.Request.Url);

                // this code from: http://stackoverflow.com/questions/5821351/how-to-set-sliding-expiration-in-my-mvc-app-that-uses-sts-wif-for-authenticati

                var sessionAuthenticationModule = (SessionAuthenticationModule)sender;

                sessionAuthenticationModule.DeleteSessionTokenCookie();

                e.Cancel = true;
            }
  }

我认为您不需要订阅活动.在开始时删除订阅,然后使用

SessionAuthenticationModule_SessionSecurityTokenReceived

ASP.Net将为您提供连线.(该模块必须命名为"SessionAuthenticationModule",默认情况下).

如果您正在进行滑动会话,那么Vittorio的这篇博文非常好:http://blogs.msdn.com/b/vbertocci/archive/2010/06/16/warning-sliding-sessions-are-closer-than -他们-appear.aspx
