.net - 如何在使用 WCF(或 WSE 3)的 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(文本/MTOM)？

Question

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)，该服务仅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 Mtom 请求!不幸的是，服务器因 Mtom 请求而阻塞并返回 500 错误。但是，如果我将其设置为文本消息编码，则响应会正确返回，并带有多部分 MIME (MTOM) 响应，该响应会导致 Microsoft Web 服务 API 出错(下面的示例错误)。它期待一个文本编码的响应，因为请求是文本编码的。我只想 RequireMtom 回复。有人可以帮我吗？

正如您在下面的错误(标准 Web 服务 API、WCF 或 WSE3 中发生的错误)中看到的，当我使用文本编码发送请求时，响应会正确返回，其中包含多部分中的所有数据/相关响应，但是.net框架卡住了!

WSE 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:

   at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters)

WCF 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:

呃!

Answer 1

是的，您可以使用 WCF 发送短信并获得 mtom 回复(反之亦然)。

看...
