Routing WCF路由服务IClientMessageInspector-->；在发送请求之前不调用

在发送到后端服务之前，我需要为WCF路由服务中的每条消息添加HTTP头。我已经实现了下面的类。但是，当我调试时，不会调用“BeforeSendRequest”，因此不会添加HTTP头ic

我注意到调用了“AfterReceiveRequest”，并添加了HTTP头，但发现头并没有发送到后台服务器

我需要在调用“BeforeSendRequest”时添加，但是，这不会触发

            return typeof(RouterMessageLogger);
        } 
    }        
    protected override object CreateBehavior()
    {
        return new RouterMessageLogger();
    }

        return null;
    }**
    public void AfterReceiveReply(ref Message reply, object correlationState)
    {
        Message MyMsg = reply;
