trace - 如何从 OpenTracing API 获取跟踪 ID？

Question

在 #105 davidB 询问:

I would like to have read access to the Span id (SpanContext id) to be able to use it in log and in error reported (to end user,...). [skip] I need to expose the "trace id" in error message, then dev could use the trace to debug error reported by support, QA, end-user.

目前OpenTracing API不暴露跟踪 ID。本期正在讨论:https://github.com/opentracing/specification/issues/24
