WSO2 ESB -克隆和聚合中介不发送回响应

Question

我在使用克隆聚合中介时遇到了一个奇怪的问题。我将登录到onComplete中并看到了数据，但这些数据从未发送回客户端。

这是我使用的代码。

<?xml version="1.0" encoding="UTF-8"?>
<api context="/OneVinmec" name="OneVinmec" xmlns="http://ws.apache.org/ns/synapse">
    <resource methods="GET" uri-template="/getPID?*">
        ...
        <outSequence>                
            <property name="info" scope="default">
                <ns:Information xmlns:ns="http://wso2.com"/>
            </property>
            <aggregate id="getPID">
                <completeCondition timeout="10">
                    <messageCount max="-1" min="-1"/>
                </completeCondition>
                <onComplete enclosingElementProperty="info" expression="//*[local-name() = 'DSBenhNhan']">
                    <log description="DSBenhNhan" level="custom">
                        <property expression="//*[local-name() = 'DSBenhNhan']" name="DSBenhNhan"/>
                    </log>
                    <send/>
                </onComplete>
            </aggregate>
            <send/>
        </outSequence>
        <faultSequence/>
    </resource>
</api>

这是我从控制台获得的日志，如您所见，有log INFO - LogMediator，但在此之后，响应将不会发回。编辑:删除内容编码头后，日志现在显示如下

感谢你的帮助！

根据[2020-02-12 15:59:27,259] DEBUG - wire HTTP-Listener I/O dispatcher-4 << "Content-Encoding: gzip[\r][\n]的说法，内容编码似乎是gzip格式的。调用API时，请跳过客户端的标头。
