我正在测试跟踪在 ASP.NET Core 3.1 中的工作方式，但有些东西不起作用。我有 3 个启用了 ActivityIdFormat.W3C 的 ASP.NET Core 应用程序（Node1、Node2、Node3），并且调用层次结构是使用 httpclient 的 Node1->Node2->Node3。当调用 Node2 时，它具有正确的 ParentId，它等于来自 Node1 的 SpanId。但是当从 Node2 ParentId 调用 Node3 时是错误的。在每个节点的日志下方 - 您可以看到我还转储了标头，看起来从 Node2 发送的标头是错误的。我在 .NET 5 中看到了相同的行为，但是当我签入没有 ActivityIdFormat.W3C 的 .NET 3.1 时，父级会在所有节点上传播。
