是否可以在没有SDK的情况下调用Dynamics CRM 2011后期绑定WCF组织服务 - 直接自定义绑定？

Question

我正在尝试实现一个纯WCF场景,我想在不依赖SDK帮助程序类的情况下调用Dynamics CRM WCF服务.基本上,我想使用.net框架中的本机WCF支持对Dynamics CRM 2011实施联合身份验证.

我这样做的原因是我想稍后将这个场景移植到BizTalk上.

我已成功使用SvcUtil生成代理类,但部分策略和安全性断言与配置架构不兼容.SvcUtil建议从代码构建绑定,这正是我想要做的.

结果代码在这里:

        private static void CallWcf()
    {
        OrganizationServiceClient client = null;

        try
        {
            // Login Live.com Issuer Binding

            var wsHttpBinding = new WSHttpBinding();
            wsHttpBinding.Security = new WSHttpSecurity();
            wsHttpBinding.Security.Mode = SecurityMode.Transport;

            // Endpoint Binding Elements

            var securityElement = new TransportSecurityBindingElement();
            securityElement.DefaultAlgorithmSuite = SecurityAlgorithmSuite.TripleDes;
            securityElement.IncludeTimestamp = true;
            securityElement.KeyEntropyMode = SecurityKeyEntropyMode.CombinedEntropy;
            securityElement.MessageSecurityVersion = MessageSecurityVersion.WSSecurity11WSTrust13WSSecureConversation13WSSecurityPolicy12BasicSecurityProfile10;
            securityElement.SecurityHeaderLayout = SecurityHeaderLayout.Strict;

            var securityTokenParameters = new IssuedSecurityTokenParameters();
            securityTokenParameters.InclusionMode = SecurityTokenInclusionMode.AlwaysToRecipient;
            securityTokenParameters.ReferenceStyle = SecurityTokenReferenceStyle.Internal;
            securityTokenParameters.RequireDerivedKeys = false;
            securityTokenParameters.TokenType = null;
            securityTokenParameters.KeyType = SecurityKeyType.SymmetricKey;
            securityTokenParameters.KeySize = 192;
            securityTokenParameters.IssuerAddress = new EndpointAddress("https://login.live.com/extSTS.srf");
            securityTokenParameters.IssuerMetadataAddress = null;
            securityTokenParameters.DefaultMessageSecurityVersion = null;
            securityTokenParameters.IssuerBinding = wsHttpBinding;

            securityElement.EndpointSupportingTokenParameters.Signed.Add(securityTokenParameters);

            var textMessageEncodingElement = new TextMessageEncodingBindingElement();
            textMessageEncodingElement.MaxReadPoolSize = 64;
            textMessageEncodingElement.MaxWritePoolSize = 16;
            textMessageEncodingElement.MessageVersion = MessageVersion.Default;
            textMessageEncodingElement.WriteEncoding = System.Text.Encoding.UTF8;

            textMessageEncodingElement.ReaderQuotas.MaxStringContentLength = 8192;
            textMessageEncodingElement.ReaderQuotas.MaxArrayLength = 16384;
            textMessageEncodingElement.ReaderQuotas.MaxBytesPerRead = 4096;
            textMessageEncodingElement.ReaderQuotas.MaxNameTableCharCount = 16384;

            var httpsTransportElement = new HttpsTransportBindingElement();
            httpsTransportElement.ManualAddressing = false;
            httpsTransportElement.AuthenticationScheme = System.Net.AuthenticationSchemes.Anonymous;

            CustomBinding binding = new CustomBinding();
            binding.Elements.Add(securityElement);
            binding.Elements.Add(textMessageEncodingElement);
            binding.Elements.Add(httpsTransportElement);

            client = new OrganizationServiceClient(binding, new EndpointAddress(EndpointUri));
            client.ClientCredentials.UserName.UserName = Username;
            client.ClientCredentials.UserName.Password = Password;
            client.Open();

            var columnSet = new schemas.microsoft.com.xrm._2011.Contracts.ColumnSet();
            var identifier = new Guid("fbf8240e-2c85-e011-ad55-1cc1de0878eb");

            columnSet.Columns = new string[] { "name" };
            var entity = client.Retrieve("account", identifier, columnSet);
        }

        finally
        {
            if (client != null)
                client.Close();
        }
    }

我是联邦身份验证的新手,很难搞清楚许多可用绑定之间的潜在差异,所以我很感激这方面的任何帮助.

这可能是可能的，但非常复杂。我们有一个使用 Dynamics 的项目，该项目已迁移到 ADFS，并且需要在刷新令牌方面添加大量额外代码（代码形式为 SDK 中的 autorefreshsecuritytoken.cs、deviceidmanager.cs 和 toolserviceproxies.cs），并且仍然使用 SDK 来完成所有操作。

请记住，您还需要在操作系统中安装 windows.identification，这是要复制的另一项功能。

最后，您始终可以使用 JustDecompile 或类似工具来查看 SDK 正在做什么。
