我试图将 wsa 寻址“来自”SOAP 标头从一项服务传递到另一项服务，但我无法传递。我有以下情况
我有代理服务，我们将从中调用另一个 WSO2 数据服务。如果代理服务从数据服务接收到故障，我将该故障消息转发到也是代理服务的常见错误处理程序。
在将消息转发到错误处理程序代理服务之前的代理服务中，我使用以下标头调解器在调用代理服务中设置标头
<header name="Action" value="urn:mediate" />
<header name="From" value="http://localhost:8280/services/TQS_SFA_CUST_SRCH" />
<header name="To" value="http://localhost:8280/services/TQS_ERROR_HANDLER" />
但是，错误处理程序代理服务从未收到“From”标头，至少从未在日志或跟踪中显示。
由于这是常见的错误处理程序，我需要知道调用来自哪个服务，以便我可以根据调用服务处理错误。
如何设置 SOAP 寻址标头，以便能够在错误处理程序中看到“From”标头？我尝试了端点调解器以及属性的消息级别设置，以将消息发送到错误处理程序。我还在端点定义中启用了 WS 寻址。看起来没有任何工作。
以下是附加的跟踪日志供您参考。
