WSO2 ESB - 修改代理服务中的输出消息内容

时间：2016-10-31 07:18:11

标签： wso2 wso2esb

我使用WSO2 ESB（4.8.1）并想知道如何获得输出，如“预期输出”块所示。

提前致谢。

代理服务定义：

    <?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
       name="DATA_WS"
       transports="https,http"
       statistics="disable"
       trace="enable"
       startOnLoad="true">
   <target>
      <inSequence>
         <switch xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
                 source="local-name(/*/*/*[1])">
            <case regex="getSavProducts">
               <payloadFactory media-type="xml">
                  <format>
                     <soapenv:Envelope xmlns:dat="http://ws.wso2.org/dataservice">
                        <soapenv:Header/>
                        <soapenv:Body>

                        </soapenv:Body>
                     </soapenv:Envelope>
                  </format>
                  <args/>
               </payloadFactory>
               <log level="custom">
                  <property name="operation" value="getSavProducts"/>
               </log>
               <send>
                  <endpoint>
                     <address uri="http://dssserver:9783/services/DATA_WS/getSavProducts"/>
                  </endpoint>
               </send>
            </case>
            <default/>
         </switch>
      </inSequence>
      <outSequence>
         <iterate xmlns:m="http://ws.wso2.org/dataservice"
                  id="iter1"
                  expression="//m:Entries/m:Entry">
            <target>
               <sequence>
                  <log level="custom">
                     <property name="output111" expression="//m:PRODUCT_DESC/text()"/>
                  </log>
                  <send/>
               </sequence>
            </target>
         </iterate>
      </outSequence>
   </target>
   <publishWSDL key="gov:/IB/DATA_WS.wsdl"/>
   <parameter name="useOriginalwsdl">true</parameter>
   <parameter name="disableOperationValidation">true</parameter>
   <description/>
</proxy>

这是我在调用服务时得到的输出

    <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Body>
      <Entry xmlns="http://ws.wso2.org/dataservice">
         <PRODUCT_CODE>2</PRODUCT_CODE>
         <SUB_PRODUCT_CODE>20</SUB_PRODUCT_CODE>
         <PRODUCT_DESC>TEST SUB PRODUCT</PRODUCT_DESC>
         <STATUS>A</STATUS>
         <PRODUCT_CATEGORY>G</PRODUCT_CATEGORY>
         <PRODUCT_NAME>General</PRODUCT_NAME>
         <CUR_CODE>GBP</CUR_CODE>
         <CHANNEL>USSD</CHANNEL>
      </Entry>
   </soapenv:Body>
</soapenv:Envelope>

使用xsl和xslt介体解决了它。
