Question

我想在ESB上公开一个API（REST），它将请求转换为SOAP服务。

我的Api以这种方式确定：

 <api xmlns="http://ws.apache.org/ns/synapse" name="__test" context="/mytest">

   <resource methods="GET" uri-template="/{symbol}">
      <inSequence>

         <property name="symbol" expression="get-property('uri.var.symbol')"/>

         <payloadFactory media-type="xml">
            <format>
                <ser:getQuote  xmlns:ser="http://services.samples" xmlns:xsd="http://services.samples/xsd">
                <ser:request>
                        <xsd:symbol>$1</xsd:symbol>
                </ser:request>
            </ser:getQuote>

            </format>
            <args>
               <arg evaluator="xml" expression="get-property('symbol')"/>
            </args>
         </payloadFactory>

         <log level="full"/>

         <send>
            <endpoint>
               <wsdl service="SimpleStockQuoteService" port="SimpleStockQuoteServiceHttpEndpoint" 
                    uri="http://localhost:9000/services/SimpleStockQuoteService?wsdl"/>
            </endpoint>
         </send>
      </inSequence>
   </resource>
</api>

但是当我用http：//：8280 / mytest / WSO2调用网址时，我在控制台上发现了这个错误

<soapenv:Reason xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope">
<soapenv:Text xml:lang="en-US">
The endpoint reference (EPR) for the Operation not found is /services/SimpleStockQuoteService.SimpleStockQuoteServiceHttpEndpoint/WSO2?request= and the WSA Action = null. If this EPR was previously reachable, please contact the server administrator.
</soapenv:Text>
</soapenv:Reason>

因为esb会将请求的 WSO2 部分附加到网址。

我怎么解决这个问题？感谢

您可以按照this指南来实现此目的。请注意，soap操作标头应添加如下，端点不同。 <header name="Action" value="urn:getQuote"/>
找到下面的完整解决方案API，

<api xmlns="http://ws.apache.org/ns/synapse" name="__test" context="/mytest"><resource methods="GET" uri-template="/{symbol}">
  <inSequence>
     <property name="symbol" expression="get-property('uri.var.symbol')"/>
     <payloadFactory media-type="xml">
        <format>
           <ser:getQuote xmlns:ser="http://services.samples" xmlns:xsd="http://services.samples/xsd">
              <ser:request>
                 <xsd:symbol>$1</xsd:symbol>
              </ser:request>
           </ser:getQuote>
        </format>
        <args>
           <arg evaluator="xml" expression="get-property('symbol')"/>
        </args>
     </payloadFactory>
     <property name="REST_URL_POSTFIX" scope="axis2" action="remove"/>
     <log level="full"/>
     <header name="Action" value="urn:getQuote"/>
     <send>
        <endpoint>
           <address uri="http://localhost:9000/services/SimpleStockQuoteService" format="soap11"/>
        </endpoint>
     </send>
  </inSequence></resource></api>

如果您想直接使用WSDL网址，可以使用WSO2 API Manager实现此目标，并且可以在WSO2 API Cloud中轻松尝试。还有一个类似的问题here。
