[英]How do I add IOperationInvoker to wcf client
I want to add my own IOperationInvoker to a wcf client but can't get it to work. 我想将自己的IOperationInvoker添加到wcf客户端但无法使其工作。 I have this 我有这个
class ClientProgram
{
static void Main()
{
CreateClient().SomeMethod();
}
private static MyServiceClient CreateClient()
{
var client = new MyServiceClient(new NetTcpBinding(), new EndpointAddress"net.tcp://localhost:12345/MyService"));
// I guess this is where the magic should happen
return client;
}
}
public class MyOperationInvoker : IOperationInvoker
{
private readonly IOperationInvoker _innerOperationInvoker;
public MyOperationInvoker(IOperationInvoker innerOperationInvoker)
{
_innerOperationInvoker = innerOperationInvoker;
}
public object Invoke(object instance, object[] inputs, out object[] outputs)
{
Console.WriteLine("Intercepting...");
return _innerOperationInvoker.Invoke(instance, inputs, out outputs);
}
// Other methods not important
}
You must have something mixed up here. 你必须在这里混淆一些东西。
The IOperationInvoker
is a server-side only extension point. IOperationInvoker
是仅服务器端的扩展点。 It allows you to inspect an incoming message and invoke a particular operation on the service based on that message (its content, headers - whatever). 它允许您检查传入的消息,并根据该消息(其内容,标题 - 无论如何)调用服务上的特定操作。
On the client side, this doesn't make sense at all - there's no way a client can use a IOperationInvoker
implementation. 在客户端,这根本没有意义 - 客户端无法使用IOperationInvoker
实现。

implementation on the server-side, check out this blog post for a complete run-down. 如果您想知道如何在服务器端添加IOperationInvoker

听起来你可能会更好地实现IClientMessageInspector扩展。
You have missed IOperationBehavior 你错过了IOperationBehavior
public class MyOperationBehavior : IOperationBehavior
{
public void ApplyDispatchBehavior(OperationDescription operationDescription, DispatchOperation dispatchOperation)
{
dispatchOperation.Invoker = new MyOperationInvoker();
}
}
