如何从requestTelemetry获取会话ID？

Question

using Microsoft.ApplicationInsights.Channel;
using Microsoft.ApplicationInsights.Extensibility;


namespace ACME.Foundation.Analytics
{
    public class ApplicationInsightsSessionInitializer : ITelemetryInitializer
    {
        public void Initialize(ITelemetry telemetry)
        {
            var requestTelemetry = telemetry as RequestTelemetry;
            if (requestTelemetry == null) return;

            if (HttpContext.Current.Session.SessionID != null)
            {
                telemetry.Context.Session.Id = HttpContext.Current.Session.SessionID;
            }
        }
    }
}

在ApplicationInsights.config中

<Add Type="ACME.Foundation.Analytics.ApplicationInsightsSessionInitializer, ACME.Foundation.Analytics" />
<Add Type="Microsoft.ApplicationInsights.StatusMonitor.SdkSourceTelemetryInitializer, Microsoft.AI.StatusMonitor" />

如何从requestTelemetry获取会话ID？我在我的分析遥测文件夹中有这个片段。看起来好像itemType请求没有会话ID。每次出现请求时，会话都为空。

我想将它与正确的sessionID匹配，并且无法在app insights sessionID中覆盖它

我跟随这里的例子：https://docs.microsoft.com/en-us/azure/application-insights/app-insights-usage-send-user-context

并将我的解决方案基于位于页面中间的演示，但似乎并不适合我。

任何帮助，将不胜感激！

按照@Dmitry的说法，这个例子是不正确的。

还有另一种方法可以设置sessionid，你可以参考这个link：

private static TelemetryClient GetTelemetryClient()
{
var telemetryClient = new TelemetryClient();
telemetryClient.InstrumentationKey = "<your actual insight instrumentkey>";
telemetryClient.Context.Session.Id = "124556";
//update 1-Custom properties- Start
telemetry.Context.Properties["tags"] = "PROD";
telemetry.Context.Properties["userCorelateId"]="1234"; 
//update 1-Custom properties- Ends                
return telemetryClient;
}
