Ich erstelle WSO2ESB Proxy-Dienst, der Daten von WSO2DSS-Server erhält und iteriert und sendet dann Anfragen in WSO2DSS.WSO2 ESB iterieren Mediator zusammen mit WSO2DSS gibt Fehler kann Parameter mit Typ nicht finden: Abfrage-Parameter
<iterate id="it"
expression="//*[local-name()='data']"
sequential="true">
<target>
<sequence>
<call>
<endpoint>
<http method="GET"
uri-template="http://localhost:9766/services/TEST/test?testId={uri.var.testId}"/>
</endpoint>
</call>
<send/>
</sequence>
</target>
</iterate>
Aber DSS gibt diesen Fehler:

Der Endpunkt http://localhost:9766/services/TEST/test?testId=1 arbeitet, aber wenn sie mit WSO2ESB in Iterierte Mediator verwendet es funktioniert nicht. Warum?
