我正在使用wso2esb 4.7.0和wso2dss 3.0.0 ..我在wso2dss中寫了一個查詢。它在dss中工作正常。也但是當我想在序列調解wso2esb 去解決它顯示錯誤如上RelayUtils在wso2esb中建立直通流錯誤時出錯

我的代理服務是：
<inSequence>
<property name="messageType" value="application/json" scope="axis2"/>
<property name="username"
expression="//username/text()"
scope="default"
type="STRING"/>
<property name="userid"
expression="//userid/text()"
scope="default"
type="STRING"/>
<log>
<property name="username" expression="get-property('username')"/>
<property name="userid" expression="get-property('userid')"/>
</log>
<payloadFactory media-type="xml">

<send/>

和順序是：
<sequence xmlns="http://ws.apache.org/ns/synapse" name="Capp_Login_seq1">
<property name="messageType" value="application/json" scope="axis2"/>
<property xmlns:ns="http://org.apache.synapse/xsd" xmlns:s="http://ws.wso2.org/dataservice" name="userid" expression="get-property('userid')" scope="default" type="STRING"/>
<log>
<property xmlns:ns="http://org.apache.synapse/xsd" name="userid" expression="get-property('userid')"/>
</log>
<send/>
</sequence>
我發送請求如下：
curl -v -H "Accept:application/json" -H "Content-Type:application/json" -d '{"username":"Harry","userid":"347367127872701992"}' http://youtility-desktop:8282/services/Capp_LoginProxy
我應該如何解決這個錯誤？請讓我知道..
您發送的請求是什麼？ – chanaka777
curl -v -H「Accept：application/json」-H「Content-Type：application/json」-d'{「mailid」：「[email protected]」，phonenumber「：」999999999「}'http： // yourtility-desktop：8282/services/Capp_muser_Registration – user3129056
你的日誌調解器怎麼樣？它們是否被打印？ 你不能使用XPATH表達式來操縱json請求，試試這個'
