那些遇到过的问题

在WSO2 ESB中，如果在调度程序任务中发起请求，为什么SOAPAction丢失？

M. *_*Tai 0 wso2 wso2esb

该项目的要求是每天进行一次Web服务调用并保存其响应。该Web服务需要YYYYMMDD格式的固定值和日期值。为此，我创建一个SEQUENCE执行以下操作：

  1. 使用Web服务的必需参数创建有效负载
  2. 使用有效负载调用Web服务端点
  3. 保存回复

然后，我创建一个使用SEQUENCE的代理服务。当我使用SoapUI运行代理时，一切正常。然后，我创建一个计划任务以调用序列。当调度程序任务运行时，该序列无法进行成功​​的Web服务调用。当我检查日志条目时，发现对于调度程序任务，SOAPAction和WSA-Action（来自定义的端点）的值都为空；对于代理服务，它们具有正确的值（https：// hostname / Get_Daily_Usage）。我暂停这是否是问题的根本原因。如果是根本原因，如何解决？如果您对此有何见解，请帮助阐明。以下是每种情况下的日志条目。先感谢您。

好吧，这是一个好问题。但是，当您向代理服务发送请求时，您正在发送所有必要的标头，例如SOAPAction等。但是任务是某些东西会自行触发并执行，并且在后台使用Quartz调度。因此，涉及任务时，您需要在突触配置中设置所有必要的标头。为此，请在使用send或call mediator调用终结点之前，将以下属性添加到任务的突触配置中。

<property name="SOAPAction" scope="transport" value="urn:getQuote"/>
