[英]C#/IRS ACA - Sending a web service request with both MTOM attachment and GZip encoding using WCF 4.5
我们正在尝试通过用于ACA数据传输的公开Web服务向IRS发送数据，并且由于安全标头中的时间戳和签名元素的顺序，我们无法使WSE 3.0方法起作用。 当TimeStamp元素出现在Signature元素之前时，IRS侧的XSD验证显示错误。 当我们使用策略断言手动生成具有正确的Signature和Timestamp元素顺序的安全头时，IRS Web服务显示“无效的WS安全头”错误。
任何人都可以遇到同样的问题，请告诉我们可能的修复方法。 使用WCF 4.5而不是WSE 3.0是解决方案，请您提供一个使用WCF 4.5处理MTOM附件和GZip编码的工作示例
任何帮助将不胜感激。
编辑：以下是我们现在发送的状态请求肥皂信封，其中包含手动创建的整个XML。 它仍然显示TPE - 1122无效的安全标头错误。 这个请求有错吗？

编辑 ：验证由于WCF的消息传递架构，这一切都不会起作用。 IRS结构需要修改HTTP头以使MTOM正常工作，在发生XML序列化之后，无法在WCF中修改。 您必须手动构建XML并通过HttpClient发送它并自己进行GZip和MTOM编码。 关于这些坏消息我很遗憾 ：（
WCF gzip：在此处获取示例，并将类和客户端配置与您的应用程序集成。 https://msdn.microsoft.com/en-us/library/ms751458.aspx
您必须将内容类型调整为“text / xml”而不是“application / x-gzip”。
这仍然会被IRS拒绝，因为这不会设置“Content-Encoding”标头。 您可以通过以下方式设置内容编码：
感谢这篇博客文章： http ： //blogs.msdn.com/b/wsdevsol/archive/2014/02/07/adding-custom-messageheader-and-http-header-to-a-wcf-method- call.aspx
此外，IRS的响应不是gzip压缩，因此您需要修改类以不尝试解压缩响应。
此外，另外，innerMessageEncoding messageVersion默认与IRS不兼容。 您必须修改GZipMessageEncodingElement的ApplyConfiguration方法，以使用Encoding.UTF8将TextMessageEncodingBindingElement实例化为MessageVersion.Soap11WSAddressing10枚举。
MTOM我的绑定看起来像这样：
<bindings>
<customBinding>
<binding name="BulkRequestTransmitterBinding">
<gzipMessageEncoding innerMessageEncoding="textMessageEncoding" />
<security enableUnsecuredResponse="true" authenticationMode="MutualCertificate" messageSecurityVersion="WSSecurity10WSTrust13WSSecureConversation13WSSecurityPolicy12BasicSecurityProfile10"/>
<httpsTransport />
</binding>
</customBinding>
</bindings>
然后是针对我的证书的自定义行为。
我还没有在你的帖子上发表评论的声誉> :(
以下是有关您正在使用的流程的几个后续问题。
