嗨，如何在有效负载中介中的WSO2 EI 611中提取上述日志中介数据的ID和价格（仅）？

Answer 1

你的xml：

<payloadFactory media-type="xml">
    <format>
        <m:checkpriceresponse xmlns:m="ws.apache.org/ns/synapse">
            <m:ID>$ctx:ID</m:ID>
            <m:Price>$ctx:Price</m:Price>
        </m:checkpriceresponse>
    </format>
    <args>
        <arg value="ID"/>
        <arg value="Price"/>
    </args>
</payloadFactory>

如果你有ID和Price作为属性，那么你需要这个代码：

<payloadFactory media-type="xml">
    <format>
        <m:checkpriceresponse xmlns:m="ws.apache.org/ns/synapse">
            <m:ID>$1</m:ID>
            <m:Price>$2</m:Price>
        </m:checkpriceresponse>
    </format>
    <args>
        <arg expression="$ctx:ID"/>
        <arg expression="$ctx:Price"/>
    </args>
</payloadFactory>
