Question

使用Wso2esb 4.9.0，我有一个服务，它从数据库中选择数据并以JSON格式给出响应。

代理服务：

序列：

<sequence xmlns="http://ws.apache.org/ns/synapse"
          name="MquestionMobile_Seq33.0"
          statistics="enable">

             name="Datalist"
             expression="//s:Datalist"
             scope="default"
             type="STRING"/>
   <property xmlns:ns="http://org.apache.synapse/xsd"

             expression="count(//s:Datalist)"
             scope="default"
             type="STRING"/>
<filter xmlns:ns="http://org.apache.synapse/xsd"
           xpath="get-property('Total')='0.0'">
      <then>
         <property name="RESPONSE" value="true" scope="default" type="STRING"/>
         <payloadFactory media-type="json">
            <format>
        {"ResponseJSON":{"Body":{"Datalist":"Not Found"},"Status":"404"}}
    </format>
            <args/>
         </payloadFactory>
         <send/>
      </then>
      <else>
         <property name="RESPONSE" value="true" scope="default" type="STRING"/>
         <property name="NO_ENTITY_BODY" scope="axis2" action="remove"/>
         <payloadFactory media-type="json">
            <format>{"ResponseJSON" : {"Body" :$1,"Status" :"200","Total" :"$2"}}</format>
            <args>
                <arg evaluator="json" expression="$.Body"/>
                <arg evaluator="xml" expression="get-property('Total')"/>

         </payloadFactory>
         <send/>
      </else>
   </filter>   
</sequence>

此服务为我提供了如下所示的响应

{"jsonObject":{"ResponseJSON" : 
    {"Body" :
    {"Datalist":[
    {"ComboValues":"Yes,No","QuestionType":0,"Tag":-1,"Question":"LogBooks","IsAVPT":-1,"QuestionId":989181535979317,"DataSize":-1.0,"ToolTip":-1,"IsFollowup":-1},
    {"ComboValues":"Yes,No","QuestionType":0,"Tag":null,"Question":"MasterRegister","IsAVPT":-1,"QuestionId":989181536700214,"DataSize":-1.0,"ToolTip":null,"IsFollowup":-1},
    {"ComboValues":null,"QuestionType":0,"Tag":null,"Question":"OthersRecords","IsAVPT":-1,"QuestionId":989181536732983,"DataSize":-1.0,"ToolTip":null,"IsFollowup":-1}]},"Status":"200","Total":"3.0"}}}

我不想在我的回复中看到jsonObject，我如何在我的JSON响应中避免这种情况并获得如下响应

{"ResponseJSON" : 
        {"Body" :
        {"Datalist":[
        {"ComboValues":"Yes,No","QuestionType":0,"Tag":-1,"Question":"LogBooks","IsAVPT":-1,"QuestionId":989181535979317,"DataSize":-1.0,"ToolTip":-1,"IsFollowup":-1},
        {"ComboValues":"Yes,No","QuestionType":0,"Tag":null,"Question":"MasterRegister","IsAVPT":-1,"QuestionId":989181536700214,"DataSize":-1.0,"ToolTip":null,"IsFollowup":-1},
        {"ComboValues":null,"QuestionType":0,"Tag":null,"Question":"OthersRecords","IsAVPT":-1,"QuestionId":989181536732983,"DataSize":-1.0,"ToolTip":null,"IsFollowup":-1}]},"Status":"200","Total":"3.0"}}

Answer 1

您可以使用rich mediator从响应主体中删除jsonObject，如下所示。

<iframe width="560" height="315" src="video.mp4"></iframe>

您可以在丰富介体后添加日志介体并检查更改的主体。

希望这会对你有所帮助。

Answer 2

在侧面ESB中介通信以SOAP消息的形式发生。当您发送JSON请求或ESB收到JSON响应时，ESB通过添加标记将其转换为xml / soap消息以防止多根xml。尝试使用

{% extends "base.html" %}
{% block content %}

<body>
<section>
    ...
</section>
<iframe src="{% for item in query_set %}{{ item }}{% endfor %}" style="width:100%;height:100%;position:absolute;margin-top:-10px;"></iframe>
{% endblock %}

发送/致电之前。这将自动从响应中删除您的jsonObject。但是如果你想从json将响应转换为xml，那么你需要使用enrich mediator

手动修改

确保在axis2.xml中启用了json格式化程序
