c# - WCF over HTTPS 和签署正文

Question

我有一个要连接的 SOAP 服务。它需要通过 https 访问，并且它的正文需要由证书签名。

我试过下面的代码:

<basicHttpBinding>
    <binding name="P4Binding" closeTimeout="00:01:00" openTimeout="00:01:00"
        receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false"
        bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
        maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
        messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
        useDefaultWebProxy="true">
        <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
            maxBytesPerRead="4096" maxNameTableCharCount="16384" />
        <security mode="TransportWithMessageCredential">
        <transport clientCredentialType="None" proxyCredentialType="None"
            realm="" />
        <message clientCredentialType="Certificate" algorithmSuite="Default" />
        </security>
    </binding>
</basicHttpBinding>

按如下方式设置我的客户端:

P4_ServiceReference.P4PortTypeClient client = new P4_ServiceReference.P4PortTypeClient();

client.ClientCredentials.ServiceCertificate.Authentication.CertificateValidationMode = System.ServiceModel.Security.X509CertificateValidationMode.None;
client.ClientCredentials.ServiceCertificate.DefaultCertificate = new X509Certificate2(@"[..].cer");
client.ClientCredentials.ClientCertificate.Certificate = new X509Certificate2(@"[..]", "somepass");

甚至更改了我的 Reference.cs 以在 ServiceContractAttribute 和 OperationContractAttribute 上包含 ProtectionLevel=ProtectionLevel.Sign。

发生的情况是创建了 wse:security header ，但未对主体进行签名。该服务返回 Element http://schemas.xmlsoap.org/soap/envelope/Body must be signed。

我缺少什么才能正确签署正文？

使用 customBinding 而不是 basicHttpBinding 修复了它。

        //Setup custom binding with HTTPS + Body Signing + Soap1.1
        CustomBinding binding = new CustomBinding();

        //HTTPS Transport
        HttpsTransportBindingElement transport = new HttpsTransportBindingElement();

        //Body signing
        AsymmetricSecurityBindingElement asec = (AsymmetricSecurityBindingElement)SecurityBindingElement.CreateMutualCertificateBindingElement(MessageSecurityVersion.WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10);
        asec.SetKeyDerivation(false);
        asec.AllowInsecureTransport = true;
        asec.IncludeTimestamp = true;

        //Setup for SOAP 11 and UTF8 Encoding
        TextMessageEncodingBindingElement textMessageEncoding = new TextMessageEncodingBindingElement(MessageVersion.Soap11, Encoding.UTF8);

        //Bind in order (Security layer, message layer, transport layer)
        binding.Elements.Add(asec);
        binding.Elements.Add(textMessageEncoding);
        binding.Elements.Add(transport);

TransportWithMessageCredential 似乎只使用 Transport 来保证安全，而忽略了其他一切。
