Question

我已经创建了具有迭代和聚合功能的API。但是，两种反应都没有结合。有时，两个响应都显示为单个。我将此请求称为POST方法，并将Info标记作为AD发送。 inSequence部分正常工作。但outSequence标签的响应均未合并。请帮助我继续执行此操作。

<?xml version="1.0" encoding="UTF-8"?>
<api context="/Info" name="InfoRequestAPI" xmlns="http://ws.apache.org/ns/synapse">
    <resource methods="POST" protocol="http">
        <inSequence>
            <property expression="$body//Request/OptionInfoRequest/Info" name="OptionInfo" scope="default" type="STRING"/>  

            <script language="js"><![CDATA[var payloadXML = mc.getPayloadXML();
                var xml = '<ItemList>';
                for each (var item in String(mc.getProperty("OptionInfo")).split(',')) {
                    xml +='<item>'+item+'</item>';
                }
                xml +='</ItemList>';
                payloadXML.appendChild(new XML(xml));
                mc.setPayloadXML(payloadXML);
                mc.setProperty("ORIGINAL_PAYLOAD",payloadXML);]]></script>

Answer 1

总的来说，enclosingElementProperty=""为什么为空，该属性为所有迭代结果充当根标记，您需要定义该属性，然后在enclosingElementProperty中使用它，类似这样

<property name="ECNCLOSING_ELEMENT" scope="default">
    <wrapper xmlns=""/>
</property>

然后

  <onComplete xmlns:ns="http://org.apache.synapse/xsd" expression="$body/*[1]" enclosingElementProperty="ECNCLOSING_ELEMENT">

我添加了以下代码。这对我来说很好。

            <property name="enclosing_element" scope="default">
                <Reply/>
            </property>


            <aggregate id="option_info_request">
                <completeCondition timeout="60">
                    <messageCount max="-1" min="-1"/>
                </completeCondition>
                <onComplete enclosingElementProperty="enclosing_element" expression="$env/*[local-name()='Body']/*">                        
                </onComplete>
            </aggregate>
