StartupAuth.cs

StartupAuth.cs

     var config1 = new CookieAuthenticationOptions
        {
            AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
            //LoginPath = new PathString("/Account/Login"),
            Provider = new CookieAuthenticationProvider
            {
                // Enables the application to validate the security stamp when the user logs in.
                // This is a security feature which is used when you change a password or add an external login to your account.  
                OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser>(
                    validateInterval: TimeSpan.FromMinutes(30),
                    regenerateIdentity: (manager, user) => user.GenerateUserIdentityAsync(manager))

            }
        };

        app.UseCookieAuthentication(config1);
        var options = new CookieAuthenticationOptions
        {
            // usual options such as LoginPath, for example, go here...
            LoginPath = new PathString("/Account/Login"),
            Provider = new CookieAuthenticationProvider
            {
                OnValidateIdentity = context =>
                {
                    DateTimeOffset now = DateTimeOffset.UtcNow;

                    context.OwinContext.Request.Set<double>("time.Remaining",
                           context.Properties.ExpiresUtc.Value.Subtract(now).TotalSeconds);

                    return Task.FromResult<object>(null);
                }
            }
        };
        app.UseCookieAuthentication(options);

控制器

  [Authorize]
public class HomeController : Controller
{
    public ActionResult Index()
    {
        //var secondsRemaining = (double)Request.GetOwinContext()
        //                            .Environment["time.Remaining"];
       return View();
    }

}

推荐答案

此答案提供了另一种存储值的方法.它将其存储为索赔.您可以尝试以下方法:如何知道OWIN Cookie何时到期?

This answer has an alternative approach of storing the value. It stores it as a claim. You could try this instead: How to know when OWIN cookie will expire?
