使用 serilog enricher nuget 包時 CorrelationId 為 Null

Question

我想將 correlationId 的值填充到我的 applicationInsights。 現在該值為空。 我已經安裝了 serilog.enrichers.correlationId nuget 包並在我的 startup.cs 文件中有 services.AddHTTPContextAccessor，但 correlationId 的值仍然為空。 我錯過了什么嗎？有什么建議嗎？ 我的來源是：- https://github.com/ekmsystems/serilog-enrichers-correlation-id

        Log.Logger = new LoggerConfiguration()
            .ReadFrom.Configuration(Configuration)
            .CreateLogger();

以上是我在 startup.cs 中的記錄器配置。 我在 appsettings.json 的 Enrich 標簽中定義的所有其他增強器都被填充，但相關 ID 為空。

這是我的測試結果：

我在下面做了什么：

在我的 asp.net 核心應用中，先安裝相關包，然后編輯Program.cs -> CreateHostBuilder ：

public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseStartup<Startup>();
                }).UseSerilog((hostingContext, loggerConfiguration) => loggerConfiguration
                    .ReadFrom.Configuration(hostingContext.Configuration).Enrich.WithCorrelationId()
                    .WriteTo.Console(outputTemplate: "[{Timestamp:HH:mm:ss} {CorrelationId} {Level:u3}] {Message:lj}{NewLine}{Exception}")
                    .WriteTo.ApplicationInsights(new TelemetryConfiguration { InstrumentationKey = "your_instrumentation_key" }, TelemetryConverter.Traces)
             );

我的包裹：

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.ApplicationInsights.AspNetCore" Version="2.17.0" />
    <PackageReference Include="Serilog.AspNetCore" Version="4.1.0" />
    <PackageReference Include="Serilog.Enrichers.CorrelationId" Version="3.0.1" />
    <PackageReference Include="Serilog.Settings.Configuration" Version="3.1.0" />
    <PackageReference Include="Serilog.Sinks.ApplicationInsights" Version="3.1.0" />
  </ItemGroup>

你尊重這個嗎？ 您需要調用services.AddHttpContextAccessor(); https://github.com/ekmsystems/serilog-enrichers-correlation-id#:~:text=You%20need%20to%20register%20the%20IHttpContextAccessor%20singleton%20so%20that%20the%20enricher%20has%20access%20to %20the%20requests%20HttpContext%20so%20that%20it%20can%20attach%20the%20correlation%20ID%20to%20the%20request/response
