使用Protobuf-net配置WCF的终结点行为

使用Protobuf-net配置WCF的终结点行为

7

我有一个WCF服务(.NET 4)，其中暴露了4个端点，其中一个端点配置了protobuf-net(V1.0.0.280)行为扩展。然而，我注意到protobuf-net行为会对所有定义的端点产生影响，包括未配置protobuf-net的端点！我已经在下面粘贴了我的配置。我是否遗漏了什么？任何帮助都将不胜感激..谢谢

    <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>

  <behaviors>
    <serviceBehaviors>
      <behavior name="MyServiceBehavior">
        <serviceMetadata httpGetEnabled="true"/>
        <serviceDebug includeExceptionDetailInFaults="true"/>
      </behavior>
    </serviceBehaviors>
    <endpointBehaviors>
      <behavior name="DefaultBehavior">
        <dataContractSerializer maxItemsInObjectGraph="2147483647" />
      </behavior>
      <behavior name="ProtoBufBehavior">
        <ProtoBufSerialization />
      </behavior>
    </endpointBehaviors>
  </behaviors>

  <bindings>
    <basicHttpBinding>
      <binding name="Http.Basic.Config" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" />

这很奇怪，但是（检查代码）我只在由WCF提供的端点内应用更改：

    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));
        }
    }

例如：给定一个端点（由WCF提供），循环遍历该端点中的每个操作（方法），并将序列化程序从DCS更改为PB。

这引发了一个有趣的可能性，即合同定义（因此操作定义）本身在所有端点之间共享 - 但是我真的不确定。如果是这种情况，我认为永远不可能在每个端点上拥有不同的处理器。然而，我不是WCF大师。这很令人困惑。
