C# Application Insights将用户名添加到遥测

当用户执行请求时，我试图在ApplicationInsights中记录用户的用户名

我一直在尝试这样做：

 public class AppInsightsInitializer : ClientIpHeaderTelemetryInitializer
    {
        private readonly IHttpContextAccessor _httpContextAccessor;

        public AppInsightsInitializer(IHttpContextAccessor httpContextAccessor) : base(httpContextAccessor)
        {
            _httpContextAccessor = httpContextAccessor;
        }

        protected override void OnInitializeTelemetry(HttpContext platformContext, RequestTelemetry requestTelemetry, ITelemetry telemetry)
        {
            var userName = _httpContextAccessor.HttpContext?.User?.Identity?.Name; // Only set when request failed...
            var ip = _httpContextAccessor.HttpContext?.Connection?.RemoteIpAddress?.ToString();
            if (userName != null) requestTelemetry.Context.User.AuthenticatedUserId= userName;
        }
    }

在

Startup.cs中注入并注册Teletry后：

 services.AddApplicationInsightsTelemetry(instrumentKey);
 services.AddSingleton<ITelemetryInitializer, AppInsights.AppInsightsInitializer>();

然后我尝试了以下代码：

 public class AppInsightsInitializer : ITelemetryInitializer
    {
        public void Initialize(ITelemetry telemetry)
        {
            var identity = WindowsIdentity.GetCurrent();
            if (identity != null)
            {
                var name = new WindowsPrincipal(identity);
                telemetry.Context.User.AuthenticatedUserId = name.Identity.Name;
            }
        }
    }

这在本地计算机上运行良好。但当我在dev环境中尝试时，它只记录服务器名而不是用户名

所以我认为我的第一个解决方案是正确的。但是，我无法通过它崩溃，因为
安全句柄已关闭
异常

有什么帮助吗？
环顾四周后，看起来这可能会解决您的问题

    public class AuthenticatedUserIdTelemetryInitializer : ITelemetryInitializer
    {
        IHttpContextAccessor httpContextAccessor;

        public AuthenticatedUserIdTelemetryInitializer(IHttpContextAccessor httpContextAccessor)
        {
            this.httpContextAccessor = httpContextAccessor;
        }

        public void Initialize(ITelemetry telemetry)
        {
            if (this.httpContextAccessor?.HttpContext?.User?.Identity?.IsAuthenticated == true)
                telemetry.Context.User.AuthenticatedUserId = this.httpContextAccessor.HttpContext.User.Identity.Name;
        }
    }

这实际上是你两个例子的结合。
我认为区别在于使用
Initialize
方法而不是重写的
OnInitializeTelemetry
方法。
可能是您的
httpContextAccessor
在Initialize方法中仍处于活动状态，而它已经在被重写的方法中释放。
不确定从
ClientIpHeaderTelemetryInitializer继承的动机是什么，以及是否相关

代码是从中复制的。
使用上述代码仍然会给我一个安全手柄已关闭。这一个是否幸运？我（终于）找到了一个时间来实际测试这段代码，它按预期（原样）工作，在ApplicationInsights中使用登录用户的实际用户名设置AuthUserID字段。这是新创建的.NETCore2.1MVC项目。
    public class AuthenticatedUserIdTelemetryInitializer : ITelemetryInitializer
    {
        IHttpContextAccessor httpContextAccessor;

        public AuthenticatedUserIdTelemetryInitializer(IHttpContextAccessor httpContextAccessor)
        {
            this.httpContextAccessor = httpContextAccessor;
        }

        public void Initialize(ITelemetry telemetry)
        {
            if (this.httpContextAccessor?.HttpContext?.User?.Identity?.IsAuthenticated == true)
                telemetry.Context.User.AuthenticatedUserId = this.httpContextAccessor.HttpContext.User.Identity.Name;
        }
    }
