C# 如何在WCF配置中为自定义绑定添加UsernameToken

我有一个WCF客户机，它有一个自定义绑定，满足UsernameToken策略。现在我想把这个绑定外包给.config。这是我的代码绑定：

AsymmetricSecurityBindingElement asymmetricBinding =
    SecurityBindingElement.CreateMutualCertificateDuplexBindingElement(
        MessageSecurityVersion.WSSecurity11WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10);
asymmetricBinding.InitiatorTokenParameters = new X509SecurityTokenParameters { InclusionMode = SecurityTokenInclusionMode.AlwaysToRecipient };
asymmetricBinding.RecipientTokenParameters = new X509SecurityTokenParameters { InclusionMode = SecurityTokenInclusionMode.Never };
asymmetricBinding.EndpointSupportingTokenParameters.Signed.Add(new UserNameSecurityTokenParameters
{
    InclusionMode = SecurityTokenInclusionMode.AlwaysToRecipient
});
asymmetricBinding.DefaultAlgorithmSuite = SecurityAlgorithmSuite.Basic256;
asymmetricBinding.IncludeTimestamp = true;
asymmetricBinding.SecurityHeaderLayout = SecurityHeaderLayout.Strict;
asymmetricBinding.MessageProtectionOrder = MessageProtectionOrder.SignBeforeEncrypt;
//...

this.Elements.Add(asymmetricBinding);
this.Elements.Add(new TextMessageEncodingBindingElement(MessageVersion.Soap11, Encoding.UTF8));
this.Elements.Add(new HttpsTransportBindingElement
{
    AuthenticationScheme = AuthenticationSchemes.Basic,
    KeepAliveEnabled = false,
    AllowCookies = false
});

我在上面的代码中添加了UserNameSecurityTokenParameters以添加令牌（它使用ClientCredentials.UserName.UserName和ClientCredentials.UserName.Password）。但在WCF配置中，我没有找到任何添加此令牌的选项。到目前为止，my.config如下所示：

也许这个链接可以帮助你：谢谢你，里卡多。可能用户名令牌是通过authenticationMode=“UserNameOverTransport”隐式设置的，但我需要不对称绑定，因为我使用两个证书进行签名和加密，并且还需要时间戳。
