我从NVMS下载了一个C＃实现示例，以了解如何实现其Web服务。它使用SOAP请求来调用不同的服务。在源代码中，有一个实现IEndpointBehavior和IClientMessageInspector的内部类，在BeforeSendRequest中，它们清除了SOAP标头，但从我得到的响应来看，最终请求仍然具有标头。我尝试了在SOAPUI控制台中打印的两个请求（带有和不带有标题），无标题请求有效，而另一个使我获得了与C＃应用程序本身相同的消息。
这是课程：
internal class CustomMessageInspector : IEndpointBehavior, IClientMessageInspector
{
public void AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection bindingParameters)
{
}
public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
{
clientRuntime.MessageInspectors.Add(this);
}
public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher)
{
}
public void Validate(ServiceEndpoint endpoint)
{
}
/*public void BeforeSendReply(ref Message reply, object correlationState)
{
reply.Headers.Clear();
}*/
//add using directive Message = System.ServiceModel.Channels.Message;
public void AfterReceiveReply(ref Message reply, object correlationState)
{
// WORKAROUND for WCF-Exception "The MessageHeader is already understood"
// (Note: The message still gets validated)
reply.Headers.Clear();
Console.WriteLine("received Response:");
Console.WriteLine("{0}\r\n", reply);
}
/// <summary>
/// Shows the sent message with and without SOAP-Header
/// </summary>
/// <param name="request"></param>
/// <param name="channel"></param>
/// <returns></returns>
public object BeforeSendRequest(ref Message request, IClientChannel channel)
{
// Fait la même chose que le clear, mais ne fonctione pas non plus...
/*request.Headers.ReplyTo = null;
request.Headers.Action = null;
request.Headers.MessageId = null;*/
Console.WriteLine("original Request:");
Console.WriteLine("{0}\r\n", request);
// Ne semble pas fonctionner, la requête est envoyée avec les headers...
request.Headers.Clear();
Console.WriteLine("without Header Request:");
Console.WriteLine("{0}\r\n", request);
return null;
}
}
“ request.Headers.Clear（）;”线应该在这里工作。 request参数是通过引用传递的，因此应从源对象中清除标头。但这是我得到的结果：
received Response:
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
<s:Header xmlns:s="http://www.w3.org/2003/05/soap-envelope" />
<soap:Body>
<soap:Fault>
<soap:Code>
<soap:Value>soap:MustUnderstand</soap:Value>
</soap:Code>
<soap:Reason>
<soap:Text xml:lang="en">MustUnderstand headers: [{http://www.w3.org/2005/08/addressing}To] are not understood.</soap:Text>
</soap:Reason>
</soap:Fault>
</soap:Body>
</soap:Envelope>
这是2个请求（带有和不带有标头，如beforesendrequest方法所打印）：
original Request:
<s:Envelope xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope">

我尝试更改mustUnderstand属性，但找不到更改它的位置。

好吧，经过一天的搜索，我有一个解决方案。实际上，Nicolas Giannone在这里WSHttpBinding in .NetStandard or .NET core提供了所有必需的代码。以下是NMVS的C＃示例中的SinglePackPing函数，已将其修改为与沙箱和V3 API配合使用。
public static Boolean SinglePackPing( MyConfig myConfig, String pingString )
{
Boolean ok = false;
string endPoint = myConfig.SinglePackServicesEndPoint;
//Defines a secure binding with certificate authentication
WSHttpBinding binding = new WSHttpBinding();
binding.Security.Mode = SecurityMode.Transport;
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Certificate;
// create a new binding based on the existing binding
var customTransportSecurityBinding = new CustomBinding( binding );
// locate the TextMessageEncodingBindingElement - that's the party guilty of the inclusion of the "To"
var ele = customTransportSecurityBinding.Elements.FirstOrDefault( x=>x is TextMessageEncodingBindingElement );
if( ele != null )
{
// and replace it with a version with no addressing
// replace {Soap12 (http://www.w3.org/2003/05/soap-envelope) Addressing10 (http://www.w3.org/2005/08/addressing)}
// with {Soap12 (http://www.w3.org/2003/05/soap-envelope) AddressingNone (http://schemas.microsoft.com/ws/2005/05/addressing/none)}
int index = customTransportSecurityBinding.Elements.IndexOf( ele );
var textBindingElement = new TextMessageEncodingBindingElement
{
MessageVersion = MessageVersion.CreateVersion(EnvelopeVersion.Soap12, AddressingVersion.None)
};
customTransportSecurityBinding.Elements[index] = textBindingElement;
}
//Creates ServiceClient, attach transport-binding, Endpoint and the loaded certificate
using( SinglePackServicesClient service = new SinglePackServicesClient( customTransportSecurityBinding, new EndpointAddress( endPoint ) ) )
{
using( X509Certificate2 cert = new X509Certificate2( myConfig.CertificateFilePath, myConfig.PrivateKeyPassword, X509KeyStorageFlags.PersistKeySet ) )
{
//Creates ServiceClient, attach transport-binding, Endpoint and the loaded certificate
service.ClientCredentials.ClientCertificate.Certificate = cert;
service.Endpoint.EndpointBehaviors.Add( new CustomMessageInspector() );
var bindingTest = service.Endpoint.Binding;
//Creates PingRequest and set the ping Input
SinglePackPingRequest ping = new SinglePackPingRequest();
ping.Input = pingString;
//Creates PingResponse, result of the request. Displays the response
SinglePackPingResponse pingResponse = service.PingSinglePack(ping);
ok = pingResponse.Output == pingString;
//Displays the response. If the request is successful, the output is equal to the input
Console.WriteLine( pingResponse.Output );
}
}
return ok;
}
希望对您有所帮助。让我知道你过得怎么样。

如Mark所建议的，解决方案是创建一个CustomBinding，并将AdressingVersion更改为None。
这是我基于上面的代码使用的代码，但为了使代码对我有用，我必须做一些必要的修改。
//add using directive System.ServiceModel;
//Defines a secure binding with certificate authentication
WSHttpBinding binding = new WSHttpBinding();
binding.Security.Mode = SecurityMode.Transport;
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Certificate;
// create a new binding based on the existing binding
var customTransportSecurityBinding = new CustomBinding(binding);
var customTransportSecurityBindingCopy = new CustomBinding(binding);
// locate the TextMessageEncodingBindingElement - that's the party guilty of the inclusion of the "To"
foreach(BindingElement element in customTransportSecurityBinding.Elements)
{
// and replace it with a version with no addressing
// replace {Soap12 (http://www.w3.org/2003/05/soap-envelope) Addressing10 (http://www.w3.org/2005/08/addressing)}
// with {Soap12 (http://www.w3.org/2003/05/soap-envelope) AddressingNone (http://schemas.microsoft.com/ws/2005/05/addressing/none)}
int index = customTransportSecurityBinding.Elements.IndexOf(element);
if (element is TextMessageEncodingBindingElement)
{
var textBindingElement = new TextMessageEncodingBindingElement
{
MessageVersion = MessageVersion.CreateVersion(EnvelopeVersion.Soap12, AddressingVersion.None)
};
customTransportSecurityBindingCopy.Elements[index] = textBindingElement;
}
}
customTransportSecurityBinding = customTransportSecurityBindingCopy;
customTransportSecurityBindingCopy = null;
//Creates ServiceClient, attach transport-binding, Endpoint and the loaded certificate
SinglePackServicesClient service = new SinglePackServicesClient(customTransportSecurityBinding, new EndpointAddress(EndPoint));
