c# - 即使调用了 beforesendrequest 方法，也强制使用 mustunderstand = 1 的 SOAP 标头
问题描述
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 他们清除了 SOAP 标头，但从我得到的响应来看，最终请求仍然有标头。我尝试了在 SOAPUI 的控制台中打印的两个请求（有和没有标题），并且无标题请求有效，而另一个得到了我在 C# 应用程序本身中得到的相同消息。
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。请求参数是通过引用传递的，因此它应该清除源对象的标头。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 headers，由 beforesendrequest 方法打印）：

解决方案
好吧，经过一天多的搜索，我有一个解决方案。事实上，Nicolas Giannone 在这里提供了所有必要的代码.NetStandard 或 .NET 核心中的 WSHttpBinding 下面是来自 NMVS 的 C# 示例的 SinglePackPing 函数，已修改为与沙箱和 V3 API 一起使用。
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;
}
我希望这对你有帮助。让我知道你是怎么办的。
