如何在 WCF 客户端服务中实现 WS 安全性（时间戳、用户名令牌、签名）

Question

我需要使用 WS-Security 实现 WCF 请求。标头必须有如下标签（Signature、UsernameToken 和 Timestamp）：

<soapenv:Header>
   <wsse:Security>
     <ds:Signature xmlns:ds="http://www.w3.org/2000/09/xmldsig#">...
     <wsse:UsernameToken wsu:Id="UsernameToken-DCF9C511">...
     <wsu:Timestamp wsu:Id="TS-DCF9C5119CC59E9AE2159888852210410">...
   </wsse:Security>
</soapenv:Header>

我已尝试使用此代码，我在标题中得到“签名”和“时间戳”标签，但“用户名令牌”标签不存在：

System.Net.ServicePointManager.ServerCertificateValidationCallback = ((sender, certificate, chain, sslPolicyErrors) => true);

Servicio.RecaudoWSPortClient client = new Servicio.RecaudoWSPortClient();
                    
//Configuration certificate
X509Certificate2 cert = new X509Certificate2();
cert.Import(@"C:\Users\jdduitama\Desktop\SCRIPTS\bis\Certificado\PKCS C#\PRUEBA.pfx", "PRUEBA", X509KeyStorageFlags.DefaultKeySet);

X509Certificate2 cert2 = new X509Certificate2();
cert2.Import(@"C:\Users\jdduitama\Desktop\SCRIPTS\bis\Certificado\Certificado.cer", "", X509KeyStorageFlags.DefaultKeySet);

//Configuration Custom Binding
TextMessageEncodingBindingElement textEncoding = new TextMessageEncodingBindingElement { MessageVersion = MessageVersion.Soap11 };
HttpsTransportBindingElement httpsTransport = new HttpsTransportBindingElement { RequireClientCertificate = true };
TransportSecurityBindingElement sec = SecurityBindingElement.CreateCertificateOverTransportBindingElement();                    
sec.EnableUnsecuredResponse = true;
                    
CustomBinding customBinding = new CustomBinding(sec, textEncoding, httpsTransport);
                                        
client.Endpoint.Binding = myBinding;
client.ClientCredentials.ServiceCertificate.Authentication.CertificateValidationMode = System.ServiceModel.Security.X509CertificateValidationMode.PeerOrChainTrust;
client.ClientCredentials.ServiceCertificate.Authentication.RevocationMode = X509RevocationMode.Offline;
client.ClientCredentials.ServiceCertificate.DefaultCertificate = cert2;
client.ClientCredentials.ClientCertificate.Certificate = cert;

client.Endpoint.Address = new System.ServiceModel.EndpointAddress("https://myservice.com/service");
client.Endpoint.Binding.SendTimeout = new TimeSpan(0, 0, 30);

client.ClientCredentials.UserName.UserName = "USERNAME";
client.ClientCredentials.UserName.Password = "PASSWORD";
                   
responseConsulta = client.ConsultaPorValidacion(requestConsulta);

我认为解决方案应该在绑定安全配置中，因为如果我在配置中使用安全模式“TransportWithMessageCredential”，我会在 Header 中获得 usernameToken 但我会丢失“Signature”和“TimeStamp”

<binding name="RecaudoWSPortSoap11">
         <security mode="TransportWithMessageCredential" />
</binding>

Answer 1

如果安全模式设置为TransportWithMessageCredential，会覆盖自定义绑定中的安全模式，所以我认为这不是解决办法。

WCF为自定义绑定提供了18种认证方式，或许你可以试试UserNameOverTransport：

TransportSecurityBindingElement sec = SecurityBindingElement.CreateUserNameOverTransportBindingElement();

您也可以尝试其他身份验证方案。更多其他认证方案，可以参考这个链接：
