我試圖在Owin訪問過期時間我用下面的例子訪問Cookie有效期owin
Access ExpireTimeSpan property of Owin Cookie Authentication to notify user of login expiry
，但我不能去上班。我得到一個錯誤的關鍵，價值確實存在。我真的很感激，如果有人能指出我正確的方向，謝謝。
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();
}
}
