在到 WCF Web 服务的 SOAP 消息中，如何将 KeyIdentifier 直接放在 SecurityTokenReference 中（内联，不使用引用令牌）

【中文标题】在到 WCF Web 服务的 SOAP 消息中，如何将 KeyIdentifier 直接放在 SecurityTokenReference 中（内联，不使用引用令牌）

【英文标题】：In SOAP message to WCF web service, how to put KeyIdentifier directly inside SecurityTokenReference (inline, without using Reference token)

【发布时间】：2016-04-11 21:00:42

【问题描述】：

我成功地通过 SoapUI 与 WCF 服务通信（我获得了有关如何配置它的规范），但是我在将这些设置复制到 .NET 应用程序时遇到了麻烦。结果表明生成的 SOAP 消息的形状（通过 Fiddler 窥视）被 Web 服务拒绝，该服务期望更严格的信封布局。

我非常接近。在这张照片上……

...您可以看到三个 SOAP 消息：

1. 将X509SecurityTokenParameters.InclusionMode 设置为AlwaysToRecipient

2. 将X509SecurityTokenParameters.InclusionMode 设置为Never

3. 预期的安全令牌，在 SoapUI 上测试。

如何使用 C# 代码从第 3 点实现信封？ 我没有使用 app.config 文件，整个配置都在 C# 代码中（但我并不致力于保持这种方式， 就这样发生了）。当前代码：

using System;
using System.Net;
using System.Security.Cryptography.X509Certificates;
using System.ServiceModel;
using System.ServiceModel.Channels;
using System.ServiceModel.Security;
using System.ServiceModel.Security.Tokens;
using System.Text;

class Program

    static void Main()
    
        X509SecurityTokenParameters x509Params = new X509SecurityTokenParameters()
        
            X509ReferenceStyle = X509KeyIdentifierClauseType.RawDataKeyIdentifier,
            InclusionMode      = SecurityTokenInclusionMode.AlwaysToRecipient,
            ReferenceStyle     = SecurityTokenReferenceStyle.External,
            RequireDerivedKeys = false
        ;

        TextMessageEncodingBindingElement encoding = new TextMessageEncodingBindingElement(MessageVersion.Soap11, Encoding.UTF8);
        HttpsTransportBindingElement transport = new HttpsTransportBindingElement();
        //transport.RequireClientCertificate = true;
        CustomBinding customBinding = new CustomBinding(security, encoding, transport);

        ServicePointManager.ServerCertificateValidationCallback = (a, b, c, d) => true;

        var twoCertificatesInOneFile = new X509Certificate2Collection();
        twoCertificatesInOneFile.Import("foo path", "foo cert pass", X509KeyStorageFlags.Exportable);
        someGeneratedServiceClass client = new someGeneratedServiceClass(customBinding, new EndpointAddress(new Uri("foo webservice address"), EndpointIdentity.CreateDnsIdentity(twoCertificatesInOneFile[0].FriendlyName)));
        client.ClientCredentials.ServiceCertificate.DefaultCertificate = twoCertificatesInOneFile[0];
        client.ClientCredentials.ClientCertificate.Certificate = twoCertificatesInOneFile[1];
        //client.Endpoint.Contract.ProtectionLevel = System.Net.Security.ProtectionLevel.None;
        client.ClientCredentials.UserName.UserName = "foo user";
        client.ClientCredentials.UserName.Password = "foo pass";

        client.someServiceCall("foo", "foo", false, out i1, out i2);
    

【参考方案1】：

我最终使用了InclusionMode = SecurityTokenInclusionMode.Never，然后劫持了消息并手动替换了错误的标签。

public class CustomProxy_portClient : GeneratedProxy_portClient

        Endpoint.Behaviors.Remove(typeof(ClientCredentials));

        return new CustomSecurityTokenManager(this);
    

    protected override ClientCredentials CloneCore()
    
        return new CustomClientCredentials(this);

    public CustomSecurityTokenManager(ClientCredentials clientCredentials) : base(clientCredentials)  

    public override SecurityTokenSerializer CreateSecurityTokenSerializer(SecurityTokenVersion version)
    
        return new CustomWSSecurityTokenSerializer();

    protected override void WriteKeyIdentifierClauseCore(XmlWriter writer, SecurityKeyIdentifierClause keyIdentifierClause)
    
        string xml;
        using(MemoryStream ms = new MemoryStream())
        
            XmlTextWriter tempWriter = new XmlTextWriter(ms, new UTF8Encoding(false));
            base.WriteKeyIdentifierClauseCore(tempWriter, keyIdentifierClause);
            xml = Encoding.UTF8.GetString(ms.ToArray());
        
        XmlDocument originalKeyIdentifierClause = new XmlDocument();
