soap节点支持mtom附件处理,所以iib会自动处理。IIB知识中心概述了这些要求:
An MTOM output message is written if all of the following criteria are met:
The Allow MTOM property is selected on the WS Extensions tab.
Validation is enabled. The Validate property on the SOAPRequest and SOAPAsyncRequest nodes controls validation of the anticipated response message and not validation of the outgoing request. MTOM output is therefore suppressed unless you set Validate to Content and value on a preceding input node or transformation node.
No child elements exist below SOAP.Attachment in the logical tree. If child elements are present, SOAP with Attachments (SwA) is used.
Elements exist in the output message that are identified as base64Binary in the associated XML Schema and whose length does not fall below a default threshold size of 1000 bytes.

因此,只需将二进制数据作为blob放在content元素中(前提是它在模式中具有正确的类型),然后如上所述配置流。
