SOAPHeader中缺少ReplyTo属性

我创建了一个WS-BPEL工作流,它可以调用异步Web服务并等待回调响应。碳应用也成功地部署到BPS中。

有关我的外部异步Web服务的详细信息
 1.它需要基于http的基本认证  2.它需要在肥皂信封中提供肥皂头  3.它将处理请求并向soap头中收到的 ReplyTo 地址发送回调,并使用 MessageID 关联回调。

BPEL流程的 deploy.xml 文件如下所示......

<?xml version="1.0" encoding="UTF-8"?>  
<deploy xmlns="http://www.apache.org/ode/schemas/dd/2007/03" 
    xmlns:callback.integration.service="http://callback.integration.service/"
    xmlns:epr="http://wso2.org/bps/bpel/endpoint/config" 
    xmlns:sample="http://wso2.org/bps/sample" 
    xmlns:ws.integration.service="http://ws.integration.service/">
   <process name="sample:Test">
      <active>true</active>
      <retired>false</retired>
      <process-events generate="all"/>
      <provide partnerLink="client">
         <service name="sample:Test" port="TestPort"/>
      </provide>
      <provide partnerLink="IntegrationService">
         <service name="callback.integration.service:IntegrationCallback" port="IntegrationResponsePort"/>
      </provide>
      <invoke partnerLink="IntegrationService">
         <service name="ws.integration.service:IntegrationService" port="IntegrationRequestPort">
            <epr:endpoint endpointReference="IntegrationService.epr"/>
         </service>
      </invoke>
   </process>
</deploy>  

IntegrationService.epr 文件看起来像这样......

<wsa:EndpointReference
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.w3schools.com uep_schema.xsd"
        xmlns:wsa="http://www.w3.org/2005/08/addressing"
        xmlns:wsdl11="http://schemas.xmlsoap.org/wsdl/">
   <wsa:Address>http://http://server:8080/integration/IntegrationService</wsa:Address>
   <wsa:Metadata>
      <id>SInvokeEPR</id>
      <qos>
         <enableAddressing />
      </qos>
      <transport type="http">
         <authorization-username>username</authorization-username>
         <authorization-password>password</authorization-password>
      </transport>
   </wsa:Metadata>
</wsa:EndpointReference>  

现在,当我从碳服务管理控制台测试bpel进程时,我确实收到了异步Web服务的请求。然而,肥皂信封看起来如下,它缺少一个正确的 ReplyTo 地址来发送回调。

<?xml version='1.0' encoding='UTF-8'?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
    <soapenv:Header xmlns:wsa="http://www.w3.org/2005/08/addressing">
        <wsa:To>http://server:8080/integration/IntegrationService</wsa:To>
        <wsa:ReplyTo>
            <wsa:Address>http://www.w3.org/2005/08/addressing/none</wsa:Address>
        </wsa:ReplyTo>
        <wsa:MessageID>urn:uuid:91ac4ebd-b100-440e-a01d-c4a5c0d8a56f</wsa:MessageID>
        <wsa:Action>http://ws.integration.service/IntegrationRequestPortType/createTask</wsa:Action>
    </soapenv:Header>
    <soapenv:Body>  
       ...
    </soapenv:Body>
</soapenv:Envelope>  

现在我需要通过回调来回复此请求。回调soap信封将包含此 MessageID ,以便回调与正确的流程实例相关联。

如何将正确的 ReplyTo 地址附加到soap标头?

如果我假设您使用WSO2 BPS(或使用Apache ODE的东西),您可以在分配中使用此副本来手动设置标题。 (http://ode.apache.org/extensions/headers-handling.html
