.NET Core 中的 wsHttpBinding 解决方法

Question

我正在寻找 dotnet core WCF wsHttpBinding 解决方法。

我知道 .net core WCF 实现目前不支持 wsHttpBinding （请参阅此处的支持矩阵https://github.com/dotnet/wcf/blob/master/release-notes/SupportedFeatures-v2.1.0.md）

我正在与似乎仅支持 wsHttpBinding 的遗留第三方服务集成。我们的技术堆栈是 .net core，因此我无法恢复到 .net 框架的完整版本或 mono 变体。

问题是是否可以通过自定义绑定使用该服务？我希望有一种解决方法，可能无法完全发挥作用，但至少允许我使用该服务。

var cBinding = new CustomBinding();
        var textBindingElement = new TextMessageEncodingBindingElement()
        {
            MessageVersion = MessageVersion.Soap12WSAddressing10
        };
        cBinding.Elements.Add(textBindingElement);
        var httpBindingElement =
            new HttpsTransportBindingElement
            {
                AllowCookies = true, MaxBufferSize = int.MaxValue, MaxReceivedMessageSize = int.MaxValue, 
            };
        cBinding.Elements.Add(httpBindingElement);


        var myEndpoint = new EndpointAddress("https://..../Service.svc/wss");
        using (var myChannelFactory = new ChannelFactory<ISearch>(cBinding, myEndpoint))
        {
            myChannelFactory.Credentials.UserName.UserName = "...";
            myChannelFactory.Credentials.UserName.Password = "...";

            ISearch client = null;

            try
            {
                client = myChannelFactory.CreateChannel();

                var result = client.Find(new Search("Criteria")).Result;

                ((ICommunicationObject)client).Close();
                myChannelFactory.Close();
            }
            catch (Exception ex)
            {
                (client as ICommunicationObject)?.Abort();
            }
        }

创建客户端并对服务进行调用，但失败，因为：

Message =“无法处理消息。这很可能是因为操作“”不正确，或者因为消息包含无效或过期的安全上下文令牌，或者因为绑定之间不匹配

算了，它们与 Core 并不完全兼容。在某些特定情况下，可能会有对 WsHttpBinding 的基本调用。你可以参考下面的例子。
服务器。

   Uri uri = new Uri("http://localhost:11011");
    WSHttpBinding binding = new WSHttpBinding();
    binding.Security.Mode = SecurityMode.None;
    using (ServiceHost sh=new ServiceHost(typeof(MyService),uri))
    {
        sh.AddServiceEndpoint(typeof(IService), binding, "");
        ServiceMetadataBehavior smb;
        smb = sh.Description.Behaviors.Find<ServiceMetadataBehavior>();
        if (smb==null)
        {
            smb = new ServiceMetadataBehavior()
            {
            };
            sh.Description.Behaviors.Add(smb);
        }
        Binding mexbinding = MetadataExchangeBindings.CreateMexHttpBinding();
        sh.AddServiceEndpoint(typeof(IMetadataExchange), mexbinding, "mex");
        sh.Opened += delegate
        {
            Console.WriteLine("Service is ready");
        };
        sh.Closed += delegate
        {
            Console.WriteLine("Service is clsoed");
        };                
        sh.Open();

客户端（自动生成）

private static System.ServiceModel.Channels.Binding GetBindingForEndpoint(EndpointConfiguration endpointConfiguration)
    {
        if ((endpointConfiguration == EndpointConfiguration.WSHttpBinding_IService))
        {
            System.ServiceModel.Channels.CustomBinding result = new System.ServiceModel.Channels.CustomBinding();
            System.ServiceModel.Channels.TextMessageEncodingBindingElement textBindingElement = new System.ServiceModel.Channels.TextMessageEncodingBindingElement();
            result.Elements.Add(textBindingElement);
            System.ServiceModel.Channels.HttpTransportBindingElement httpBindingElement = new System.ServiceModel.Channels.HttpTransportBindingElement();
            httpBindingElement.AllowCookies = true;
            httpBindingElement.MaxBufferSize = int.MaxValue;
            httpBindingElement.MaxReceivedMessageSize = int.MaxValue;
            result.Elements.Add(httpBindingElement);
            return result;
        }  

调用。

ServiceReference1.ServiceClient client2 = new ServiceReference1.ServiceClient();
try
{
    var res = client2.SayHelloAsync();
    Console.WriteLine(res.Result);

}
catch (Exception)
{
    throw;
}

而在大多数情况下，无法调用 WsHttpBinding 创建的 WCF 服务。官方也无意继续支持wshttpbinding计划。以下是相关讨论。 https://github.com/dotnet/wcf/issues/31
