OpenID ASP MVC验证(长时间失效)

从 MSDN - Explained: Forms Authentication in ASP.NET 2.0 :

FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1,
    "userName",
    DateTime.Now,
    new DateTime(2020, 01, 01), // value of time out property
    false, // Value of IsPersistent property
    String.Empty,
    FormsAuthentication.FormsCookiePath);

string encryptedTicket = FormsAuthentication.Encrypt(ticket);

HttpCookie authCookie = new HttpCookie(
                        FormsAuthentication.FormsCookieName, 
                        encryptedTicket);

authCookie.Secure = true;

Response.Cookies.Add(authCookie);

你可以使用 FormsAuthentication.RenewTicketIfOld() 更新票据。此方法将检查当前票据是否已过期,如果没有,则延长其过期时间。您可以在每次请求您的站点时调用此方法,当用户继续使用您的站点时,此方法将在将来“滑动”到到期日。
