無法獲得響應JSON格式彙總後WSO2 ESB

Question

我有一個代理服務來搜索多個系統用戶，應該返回JSON format.I結合反應得到的答覆合併而是獲得它以JSON格式我收到了XML格式的回覆。 我可以看到在WSO2服務器日誌JSON迴應如下：

[2016-07-19 07:26:58,249] INFO - LogMediator To: http://www.w3.org/2005/08/addr 
essing/anonymous, WSAction: , SOAPAction: , MessageID: urn:uuid:895c4303-6de5-49

] 
}

ewableIdentityAttributes":{"Email":"Kevin.Mollo@companyb.com","cn":"Kevin Mollo" 
,"Last Name":"Mollo","First Name":"Kevin"},"assignedRoles":[],"listAttributes":[ 
"First Name","Last Name","Email","cn"]} 

不過，我不叫代理URL後獲得JSON格式的響應。 下面是我的ESB配置：

<?xml version="1.0" encoding="UTF-8"?> 
<proxy xmlns="http://ws.apache.org/ns/synapse" 
     name="SPRSAPproxy"

        <send> 
        <endpoint>

     </inSequence> 
     <outSequence> 
     <log level="full" description=""> 
      <property name="Component" expression="get-property('Application')"/> 
     </log> 
     <aggregate> 
      <completeCondition> 
       <messageCount min="2"/> 
      </completeCondition> 
      <onComplete expression="/"> 
       <property name="messageType" 
         value="application/xacml+json" 
         scope="axis2" 
         type="STRING" 
         description="messageType"/> 
       <enrich> 
        <source clone="true" xpath="/"/> 
        <target type="body"/> 
       </enrich> 
       <send/> 
      </onComplete> 
     </aggregate> 
     </outSequence> 
     <faultSequence> 
     <log level="full" category="WARN"/> 
     </faultSequence> 
    </target> 
    <description/> 
</proxy> 

我得到如下回應：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"><soapenv:Header/><soapenv:Body><jsonObject><findUsers><id>20</id><add_state>0</add_state><remove_state>0</remove_state><supervisor_id_name></supervisor_id_name><idc_id>3</idc_id><backup_supervisor_name></backup_supervisor_name><backup_supervisor></backup_supervisor><business_unit_id></business_unit_id><company>companyb</company><creation_date>2016-05-11 18:02:42.0</creation_date><deletion_date></deletion_date><department>922</department><display_name>Kevin Mollo (companyb)</display_name><email_address>Kevin.Mollo@companyb.com</email_address><exception_count></exception_count><first_name>Kevin</first_name><is_terminated>False</is_terminated><job_status>Active</job_status><last_name>Mollo</last_name><legacy_employee_id>171352</legacy_employee_id><supervisor_id></supervisor_id><termination_date></termination_date><title>Broadband Technician</title><unique_id>9000070</unique_id><user_id>user71</user_id><violation_count></violation_count></findUsers></jsonObject><soapenv:Envelope><soapenv:Header/><soapenv:Body><jsonObject><viewableIdentityAttributes><Email>Kevin.Mollo@companyb.com</Email><cn>Kevin Mollo</cn><Last Name>Mollo</Last Name><First Name>Kevin</First Name></viewableIdentityAttributes><listAttributes>First Name</listAttributes><listAttributes>Last Name</listAttributes><listAttributes>Email</listAttributes><listAttributes>cn</listAttributes></jsonObject></soapenv:Body></soapenv:Envelope></soapenv:Body></soapenv:Envelope> 

請讓我知道我怎樣才能得到JSON響應。 任何幫助將不勝感激。

Answer 1

您可以設置爲messageType應用/ JSON，而不是應用程序/ XACML + JSON在outSequence和嘗試。

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

還沒有應用/ XACML + JSON消息格式化和消息建設者默認使用WSO2 ESB發貨。如果您需要使用這些格式，則必須編寫自己的格式化程序和構建程序，並將它們配置爲axis2.xml文件。
