请求 ID 为 |574e8e13-4e9d31fed64d4793。

当我查看文件中的日志条目时，我看到：

}

所以它似乎是匹配的SpanId而不是RequestId.

所以我的问题：

  1. 我正在观看 Pluralsight 课程，屏幕截图似乎可以RequestId正常显示。他的节目正确RequestId而我的节目怎么可能SpanId？
  2. 我创建了一个新项目，据我所知，以与 repo 相同的方式实现了所有内容，但在我的日志属性中没有得到SpanId、TraceId或。ParentId猜猜我可能错过了什么？
  3. 是否应该SpanId在 WebApi 和网站调用之间匹配（即上面的两个日志，第一个是 Web API，第二个是 Web Site，并且都具有唯一的 Span/Request ID）？还是我应该使用 CorrelationId？
  4. 一般问题，SpanId、TraceId 和 HttpContext.TraceIdentifier 有什么区别？我的 error.cshtml 是否应该只使用TraceIdentifier而不是查看 Activity.Current.Id？

更新：我在 .NET 5 中实现了我的项目。这可能是日志中缺少属性的罪魁祸首，但其余问题仍然有效。

更新：我已经找到了 .NET 5 中缺少属性的解决方法。而且我还TraceId跨越了从站点到 api 的调用，但我想知道SpanId代表什么，我在网上很难找到它。
