WSO2 API Manager 3.1.0 无法从中介序列调用 GET HTTP 方法

Question

Unable to call GET APIs through the Mediation sequence in API Manager 3.1.0. The GET API call is behaving as a POST with No Body. My code is below.

            <property name="HTTP_METHOD" value="GET" scope="axis2" type="STRING"/>
            <property name="REST_URL_POSTFIX" scope="axis2" action="remove"/>
            <property name="messageType" value="application/json" scope="axis2" type="STRING"/>
            <property name="ContentType" value="application/json" scope="axis2" type="STRING"/>
            <property name="Authorization" expression="get-property('Credentials')" scope="transport" type="STRING"/>
            <property name="uri.var.tenantDomain" expression="get-property('tenantDomain')" scope="default" type="STRING"/>
            <property name="NO_ENTITY_BODY" action="remove" scope="axis2"/>
            <call blocking="true">
                <endpoint>
                    <http method="GET" uri-template="https://localhost:9443/t/{uri.var.tenantDomain}/api/users/v1/me/challenges"/>
                </endpoint>
            </call>

This is for challenge questions, whenever the URI is the same for POST and other Methods, only POST is working fine and not PUT, GET and DELETE. The same issue was observed with SCIM2 APIs too, but I changed from SCIM2 to SOAP Admin services to resolve the issue. OTher GET APIs for Recovery are working fine. Only when the URI is the same for GET/PUT/DELETE and POST, this behavior is observed from mediation sequence

The same code works in EI 6.6.0

This is similar to the following[1] and the issue is due to the IS-KM certificate-based authenticator.
