asp.net-mvc - 我们可以个性化 ASP.NET MVC 5 中角色的 session 超时吗

Question

这个想法是为 session 超时设置不同的值
ASP.NET MVC 5 和 ASP.NET Identity 中的不同用户角色。

有可能吗？

如果您试图比普通用户更快地启动管理员，这是我在 Identity 中的 stub 。

app.UseCookieAuthentication(new CookieAuthenticationOptions
{
    // other stuff
    Provider = new CookieAuthenticationProvider
    {
        // this function is executed every http request and executed very early in the pipeline
        // and here you have access to cookie properties and other low-level stuff. 
        // makes sense to have the invalidation here
        OnValidateIdentity = async context =>
        {
            // invalidate user cookie if user's security stamp have changed
            var invalidateBySecirityStamp = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser>(
                    validateInterval: TimeSpan.FromMinutes(30),
                    regenerateIdentity: (manager, user) => user.GenerateUserIdentityAsync(manager));
            await invalidateBySecirityStamp.Invoke(context);

            // check if user is in admin role
            var isAdmin = context.Identity.Claims.Any(c => c.Type == ClaimTypes.Role && c.Value == "AdminRoleName");

            // check if enough time has passed to invalidate cookie
            var currentUtc = DateTimeOffset.UtcNow;
            if (context.Options != null && context.Options.SystemClock != null)
            {
                currentUtc = context.Options.SystemClock.UtcNow;
            }

            var issuedUtc = context.Properties.IssuedUtc;
            var bootThemOut = (issuedUtc == null);
            if (issuedUtc != null)
            {
                var timeElapsed = currentUtc.Subtract(issuedUtc.Value);
                bootThemOut = timeElapsed > TimeSpan.FromMinutes(3); // invalidate admin cookies in 3 minutes
            }

            if (isAdmin && bootThemOut)
            {
                context.RejectIdentity();
                context.OwinContext.Authentication.SignOut(context.Options.AuthenticationType);
            }
        }
    }
});
