Question

我有一台安装了DSS功能的WSO2 ESB服务器。当我使用＆＃34; accept：application / json＆＃34;来调用REST服务时在请求标头中，我没有收到JSON响应，只接收XML。

Best，Ivan

在这个api中获取json的响应我使用了这两个属性

<property name="Accept" value="application/json" scope="transport" type="STRING"/>
<property name="messageType" value="application/json" scope="axis2"/>

您可以在此处查看实施

<api xmlns="http://ws.apache.org/ns/synapse" name="showById" context="/getById">
   <resource methods="POST GET" uri-template="/getEmployeeXML/{Id}">
      <inSequence>
         <property name="getId" expression="get-property('uri.var.Id')" scope="default" type="STRING"/>
         <log>
            <property name="ID" expression="get-property('getId')"/>
         </log>
         <property name="Accept" value="application/json" scope="transport" type="STRING"/>
         <property name="messageType" value="application/json" scope="axis2"/>
         <payloadFactory media-type="xml">
            <format>
               <p:getEmployeeXML xmlns:p="arce.farmacy">
                  <xs:Id xmlns:xs="arce.farmacy">$1</xs:Id>
               </p:getEmployeeXML>
            </format>
            <args>
               <arg evaluator="xml" expression="get-property('getId')"/>
            </args>
         </payloadFactory>
         <property name="Action" value="urn:getEmployeeXML" scope="transport" type="STRING"/>
         <property name="SOAPAction" value="urn:getEmployeeXML" scope="transport" type="STRING"/>
         <property name="REST_URL_POSTFIX" scope="axis2" action="remove"/>
          <send>
            <endpoint>
               <address uri="http://169.254.193.10:9763/services/StoreProcedureFarmacy" format="soap11"/>
            </endpoint>
         </send>
      </inSequence>
      <outSequence>
         <log level="full"/>
         <send/>
      </outSequence>
      <faultSequence>
         <sequence key="{faultSEQ}"/>
      </faultSequence>
   </resource>
</api>

这是回复

{
  "Employees": {
    "Employe": [
      {
        "Id": 5,
        "Description": "Office 2"
      }
    ]
  }
}

集成了DSS的WSO2 ESB不响应JSON
