如何使用WCF(或WSE 3)在Web服务客户端应用程序的请求和响应中混合消息编码类型(Text/MTOM)？

这是我的问题.我正在访问一个Web服务(托管在基于Java的服务器上),它只接受文本编码的请求,但它返回MTOM响应.我发现如果我将Web服务设置为RequireMtom,它会发送一个Mtom请求!不幸的是,服务器在Mtom请求上窒息并返回500错误.但是,如果我将其设置为文本消息编码,则响应会使用多部分MIME(MTOM)响应正确返回,该响应会使Microsoft Web服务API出错(下面的示例错误).它期望文本编码响应,因为请求是文本编码的.我想仅在响应中使用RequireMtom.有人能帮我一下吗？

正如您在下面的错误中看到的那样(使用标准Web服务API,WCF或WSE3),当我使用文本编码发送请求时,响应会正确返回多部分/相关响应中的所有数据,但是.net框架扼流圈!

WSE的错误消息:

Client found response content type of 'multipart/related; type="text/xml"; start="<1AE0B46A85B0186B5D136D12E1EE286E>";  boundary="----=_Part_209564_1891070135.1226526701833"', but expected 'text/xml'.
The request failed with the error message:

WCF的错误消息

The content type multipart/related; type="text/xml"; start="<30ED8FE3004CDA67723CC7164A6CFEEC>";    boundary="----=_Part_209545_389093169.1226526546805" of the response message does not match the content type of the binding (text/xml; charset=utf-8). If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly. The first 1024 bytes of the response were:

WSE 3.0:MTOM请求的MTOM响应是强制性的吗？

UHG!

是的,您可以发送短信并使用WCF获得mtom回复(或反之亦然).
