asp.net-core2.0用户20-30分钟后自动注销

如何在ASP.NET Core 2.0中实现用户自动注销功能

csharp
services.Configure(options =>
{
    options.CheckConsentNeeded = context => true;
    options.MinimumSameSitePolicy = SameSiteMode.None;
    options.ExpireTimeSpan = TimeSpan.FromMinutes(20);
});

csharp
app.Use(async (context, next) =>
{
    var httpContextAccessor = context.RequestServices.GetService();
    if (httpContextAccessor.HttpContext?.User?.Identity?.IsAuthenticated == true)
    {
        var sessionTimeout = TimeSpan.FromMinutes(20);
        var sessionStartedAt = httpContextAccessor.HttpContext.User.Claims
            .FirstOrDefault(c => c.Type == ClaimTypes.AuthenticationMethod)?.Value;
        if (!string.IsNullOrEmpty(sessionStartedAt))
        {
            var startTime = DateTime.Parse(sessionStartedAt);
            var elapsedTime = DateTime.UtcNow - startTime;
            if (elapsedTime > sessionTimeout)
            {
                // 执行用户注销操作
                await context.SignOutAsync();
            }
        }
    }
    await next.Invoke();
});
