二进制中继不会在wso2 EI和wso2 API管理器中扩展SOAP消息

Question

We are using wso2 api manager (2.1.0) to manage our SOAP apis. The reponse message of a our web service has content type "application/dime". We change axis2.xml to use binary-relay (builder and formatter) with that content type.

<messageFormatter contentType="application/dime"                          
   class="org.wso2.carbon.relay.ExpandingMessageFormatter"/>

<messageBuilder contentType="application/dime"
   class="org.wso2.carbon.relay.BinaryRelayBuilder"/>

The response SOAP message is not expanded, so we have a return envelope like this

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
    <ns:binary xmlns:ns="http://ws.apache.org/commons/ns/payload">DCAAAAApACkAAAJxdXVpZDo3MTRDNk...U9GCgA=</ns:binary>
</soapenv:Body>
</soapenv:Envelope> 

We saw the same behaviour with wso2 enterprise integrator (6.1.1).

Is there any configuration that we have to do to enable expanding of response SOAP message in api manager or enterprise integrator? Would we do something else?

Answer 1

也许未保留API Manager中的Content-Type，请看以下内容： WSO2 api Manager不传播多部分表单数据的内容类型头，您可以将属性http.headers.preserve设置为保留Content-Type 。

Answer 2

The APIM is working as expected in this scenario. You have set the binary formatters for your content type. So APIM,ESB treat your payload as a binary content and pass the same binary content inside a soap envelop.

You need to define the correct formatter and builder for your content type "application/dime". Refer [1] on how Message Builders and Formatters work. Identify the correct formatter and builder for your type.
