wcf - 使用 Protobuf-net 的端点行为配置 WCF

Question

我有一个 WCF 服务 (.NET 4)，它公开 4 个端点，其中一个端点配置有 protobuf-net (V1.0.0.280) 行为扩展。但是，我注意到 protobuf-net 行为会在所有定义的端点上启动，包括未配置 protbuf-net 的端点!我已将我的配置粘贴在下面。我错过了什么吗？非常感谢任何帮助..thx

    <service name="MyService" behaviorConfiguration="MyServiceBehavior">
    <endpoint address="Http.Basic" binding="basicHttpBinding" bindingConfiguration="Http.Basic.Config" contract="IMyService" behaviorConfiguration="DefaultBehavior" />
    <endpoint address="Http.Binary" binding="customBinding" bindingConfiguration="Http.Binary.Config" contract="IMyService" behaviorConfiguration="DefaultBehavior" />
    <endpoint address="Tcp.Binary" binding="customBinding" bindingConfiguration="Tcp.Binary.Config" contract="IMyService" behaviorConfiguration="DefaultBehavior" />
    <endpoint address="Http.ProtoBuf" binding="basicHttpBinding" bindingConfiguration="Http.Basic.Config" contract="IMyService" behaviorConfiguration="ProtoBufBehavior" />
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:8085/MyService"/>
        <add baseAddress="net.tcp://localhost:8086/MyService"/>
      </baseAddresses>
    </host>
  </service>

这很奇怪，但是(检查代码)我只在 WCF 提供给我的端点内应用更改:

    void IEndpointBehavior.ApplyClientBehavior(ServiceEndpoint endpoint, System.ServiceModel.Dispatcher.ClientRuntime clientRuntime)
    {
        ReplaceDataContractSerializerOperationBehavior(endpoint);
    }

    void IEndpointBehavior.ApplyDispatchBehavior(ServiceEndpoint endpoint, System.ServiceModel.Dispatcher.EndpointDispatcher endpointDispatcher)
    {
        ReplaceDataContractSerializerOperationBehavior(endpoint);
    }

    private static void ReplaceDataContractSerializerOperationBehavior(ServiceEndpoint serviceEndpoint)
    {
        foreach (OperationDescription operationDescription in serviceEndpoint.Contract.Operations)
        {
            ReplaceDataContractSerializerOperationBehavior(operationDescription);
        }
    }


    private static void ReplaceDataContractSerializerOperationBehavior(OperationDescription description)
    {
        DataContractSerializerOperationBehavior dcsOperationBehavior = description.Behaviors.Find<DataContractSerializerOperationBehavior>();
        if (dcsOperationBehavior != null)
        {
            description.Behaviors.Remove(dcsOperationBehavior);
            description.Behaviors.Add(new ProtoOperationBehavior(description));
        }
    }

即“给定一个端点(通过 WCF)，循环该端点中的每个操作(方法)，并将序列化器从 DCS 更改为 PB”

这提出了一种有趣的可能性，即契约定义(以及操作定义)本身在所有端点之间共享 - 但老实说我对此并不确定。如果是这种情况，我认为每个端点不可能有不同的处理器。然而，我不是 WCF 大师。这……令人费解。
