Wso2 将多部分/表单数据从ESB发送到APIM

我正在使用WSO2 ESB 6.4.0和APIM 2.6.0

我正在使用APIM应用程序的RESTAPI在APIM服务器中添加证书。 在添加新证书的请求中，post请求应该是表单数据

因此，为了自动化这个过程，我使用ESB服务器。我已经编写了一个代理，它将选择证书文件并对其进行处理。下面是我的代理代码

从错误日志来看，APIM服务器似乎无法从ESB获取附加文件，这就是它无法处理请求的原因

APIM 2.6.0是否支持多部分/表单数据

谢谢

我们遇到了类似的问题，我们必须在axis2/axis2.xml文件（ESB和APIM中）中更新messageFormatters和messageBuilders：

更新消息格式化程序：

<!-- <messageFormatter contentType="multipart/form-data" 
  class="org.apache.axis2.transport.http.MultipartFormDataFormatter"/ -->
<messageFormatter contentType="multipart/form-data" 
  class="org.wso2.carbon.relay.ExpandingMessageFormatter"/>

更新消息生成器

<!-- messageBuilder contentType="multipart/form-data"
  class="org.apache.axis2.builder.MultipartFormDataBuilder"/ -->
 <messageBuilder contentType="multipart/form-data"
  class="org.wso2.carbon.relay.BinaryRelayBuilder"/>

这些更新应该更改传输以流式传输负载，而无需解析和重建负载

<!-- <messageFormatter contentType="multipart/form-data" 
  class="org.apache.axis2.transport.http.MultipartFormDataFormatter"/ -->
<messageFormatter contentType="multipart/form-data" 
  class="org.wso2.carbon.relay.ExpandingMessageFormatter"/>

<!-- messageBuilder contentType="multipart/form-data"
  class="org.apache.axis2.builder.MultipartFormDataBuilder"/ -->
 <messageBuilder contentType="multipart/form-data"
  class="org.wso2.carbon.relay.BinaryRelayBuilder"/>
