我已经创建了WCF 4路由服务并以编程方式对其进行配置。我的代码比它需要的空间要多一点(可维护性是其他人关注的,因此评论),但它确实有效。这有两个过滤器:一个过滤器给特定端点一些特定的动作,第二个过滤器将剩下的动作发送到一个通用端点。
// 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)));
