c# - 为什么使用 WS-federation 的身份验证票证会在 30 分钟后过期？

Question

我在方法中有以下代码ConfigureServices：

var federationSettings = new FederationSettings();

this.Configuration.GetSection(nameof(FederationSettings)).Bind(federationSettings);
            
Microsoft.IdentityModel.Logging.IdentityModelEventSource.ShowPII = true;
CryptoProviderFactory.Default.CustomCryptoProvider = new Sha1Provider();
services.AddAuthentication(sharedOptions =>
{
    sharedOptions.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
    sharedOptions.DefaultSignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
    sharedOptions.DefaultChallengeScheme = WsFederationDefaults.AuthenticationScheme;
    sharedOptions.DefaultSignOutScheme = WsFederationDefaults.AuthenticationScheme;
})
    .AddWsFederation(options =>
    {
        options.UseTokenLifetime = false;
        options.SecurityTokenHandlers.Clear();
        options.SecurityTokenHandlers.Add(new CustomSamlSecurityTokenHandler());
        options.SecurityTokenHandlers.Add(new Saml2SecurityTokenHandler());
        options.SecurityTokenHandlers.Add(new JwtSecurityTokenHandler());
        options.RequireHttpsMetadata = false;
        options.Wtrealm = federationSettings.Realm;
        options.MetadataAddress = federationSettings.AdfsMetadataUrl;

    })
    .AddCookie(options =>
    {
        options.Cookie.Name = "AuthenticationCookie";
        options.ExpireTimeSpan = TimeSpan.FromDays(10);
        options.SlidingExpiration = true;
                 
    });

如果我设置ExpireTimeSpan为 10 秒，则身份验证票证将在 10 秒后过期，但如果我将其设置为超过 30 分钟，它将不起作用。我怎样才能增加ExpireTimeSpan？
