在WSO2 EI 6.6.0中调用带有DSS端点的API时出错

编程问答 2022-07-26

问题描述

我正在尝试使用Dataservice端点调用API。这是API的顺序。

<?xml version="1.0" encoding="UTF-8"?>
<sequence name="atms-v1-getATMInfo-in-sequence" xmlns="http://ws.apache.org/ns/synapse">
    <property name="SEQ_NAME" scope="default" type="STRING" value="atms_v1_getATMInfo_inSeq"/>
    <property action="remove" name="TRANSPORT_HEADERS" scope="axis2"/>
    <header name="Accept" scope="transport" value="application/json"/>
    <log level="full"/>
    <call>
        <endpoint name="AtmInfoEndPoint">
            <address uri="https://127.0.0.1:8243/services/atmService"/>
        </endpoint>
    </call>
    </response>
</sequence>

但是当我调用API时，我收到错误消息

[2020-09-17 07:22:58,565] ERROR {org.apache.synapse.transport.passthru.ServerWorker} - Error processing GET request for : /services/atmService/atms org.apache.axis2.AxisFault: The endpoint reference (EPR) for the Operation not found is /services/atmService/atms and the WSA Action = null.

我查看了一些文档，但找不到答案。请有人，让我知道如何解决此问题。谢谢。

解决方法

您必须在调用端点之前设置soap 操作。肥皂动作应该是数据服务的操作名称：

<property name="SOAPAction" scope="transport" value="urn:op_name"/>
