C#/IRS ACA - 使用 WCF 4.5 发送带有 MTOM 附件和 GZip 编码的 Web 服务请求

Question

我们正在尝试通过公开的 Web 服务向 IRS 发送数据以进行 ACA 数据传输，但由于安全 header 中时间戳和签名元素的顺序，我们无法使 WSE 3.0 方法发挥作用。当 TimeStamp 元素出现在 Signature 元素之前时，IRS 端的 XSD 验证显示错误。当我们使用策略断言手动生成具有正确顺序的签名和时间戳元素的安全 header 时，IRS Web 服务显示“无效的 WS 安全 header ”错误。

谁有同样的问题，请告诉我们可能的解决方法。使用 WCF 4.5 而不是 WSE 3.0 是解决方案，您能否提供一个使用 WCF 4.5 处理 MTOM 附件和 GZip 编码的工作示例

如有任何帮助，我们将不胜感激。

编辑: 以下是我们现在发送的状态请求 Soap 信封，其中包含手动创建的整个 XML。它仍然显示 TPE - 1122 Invalid Security Header Error。这个请求有没有错误？

Answer 1

编辑:已验证由于 WCF 的消息传递架构，这些都不起作用。 IRS 结构需要修改 HTTP header 才能使 MTOM 正常工作，这在 XML 序列化发生后无法在 WCF 中修改。您必须手动构建 XML 并通过 HttpClient 发送它，然后自己进行 GZip 和 MTOM 编码。对不起坏消息:(

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，因为它没有设置“Content-Encoding” header 。您可以这样设置内容编码:

<删除> 使用(新的 OperationContextScope(transmitterClient.InnerChannel))
{
//向传出请求添加 HTTP header
HttpRequestMessageProperty requestMessage = new HttpRequestMessageProperty();
requestMessage.Headers["Content-Encoding"] = "gzip";
OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = requestMessage;
返回端口.BulkRequestTransmitter(请求);
}

感谢这篇博文: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 的响应未压缩，因此您需要修改类以不尝试解压缩响应。

此外，innerMessageEncoding messageVersion 默认值与 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

多线程我的绑定(bind)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。
