WCF路由 - 如何以编程方式正确添加过滤器表

Jef*_*yer 3 wcf wcf-routing

我正在使用WCF 4路由服务,需要以编程方式配置服务(而不是通过配置).我看到这样做的例子很少见,它创建了一个MessageFilterTable,如下所示:

            var filterTable=new MessageFilterTable<IEnumerable<ServiceEndpoint>>();

但是,该方法的泛型参数应该是TFilterData(您要过滤的数据类型)?我有自己的自定义过滤器,接受一个字符串 - 我仍然可以这样创建过滤表吗?

如果这样可行......路由基础设施是否会在我传入的列表中创建客户端端点?

我创建了一个WCF 4路由服务并以编程方式配置它.我的代码比它需要的间隔更多(其他人的可维护性是一个问题,因此评论),但它肯定有效.这有两个过滤器:一个过滤器对给定端点过滤某些特定操作,第二个过滤器将其余操作发送到通用端点.

        // Create the message filter table used for routing messages
        MessageFilterTable<IEnumerable<ServiceEndpoint>> filterTable = new MessageFilterTable<IEnumerable<ServiceEndpoint>>();

        // If we're processing a subscribe or unsubscribe, send to the subscription endpoint
        filterTable.Add(
            new ActionMessageFilter(
                "http://etcetcetc/ISubscription/Subscribe",
                "http://etcetcetc/ISubscription/KeepAlive",
                "http://etcetcetc/ISubscription/Unsubscribe"),
            new List<ServiceEndpoint>()
            {
                new ServiceEndpoint(
                    new ContractDescription("ISubscription", "http://etcetcetc/"),
                    binding,
                    new EndpointAddress(String.Format("{0}{1}{2}", TCPPrefix, HostName, SubscriptionSuffix)))
            },
            HighRoutingPriority);

        // Otherwise, send all other packets to the routing endpoint
        MatchAllMessageFilter filter = new MatchAllMessageFilter();
        filterTable.Add(
            filter,
            new List<ServiceEndpoint>()
            {
                new ServiceEndpoint(
                    new ContractDescription("IRouter", "http://etcetcetc/"),
                    binding,
                    new EndpointAddress(String.Format("{0}{1}{2}", TCPPrefix, HostName, RouterSuffix)))
            },
            LowRoutingPriority);

        // Then attach the filter table as part of a RoutingBehaviour to the host
        _routingHost.Description.Behaviors.Add(
            new RoutingBehavior(new RoutingConfiguration(filterTable, false)));
