c# - WCF 4.0 路由与 mex 使用 System.ServiceModel.Routing.RoutingService

Question

我在工作 MEX 服务于:

net.tcp://remotehost:4508

什么是最短的 C#/F# 代码(很难理解 XML 配置文件 ^_^")，我可以编写它来创建一个路由器？:

net.tcp://localhost:4508

MEX 也应该正确路由，以便客户端可以使用路由器

svcutil net.tcp://localhost:4508

发现服务方法。

这是我对我的问题的回答，它完全符合我的要求——没有任何 XML 沙拉，在不到 50 行的 F# 中:

namespace CORSIS

module Application =

    open System

    open System.ServiceModel
    open System.ServiceModel.Routing
    open System.ServiceModel.Dispatcher
    open System.ServiceModel.Description


    let createSimpleRouter createBinding (routerAddress : string) serviceAddress = 

        let routerType = typeof<IRequestReplyRouter>
        let routerContract = ContractDescription.GetContract(routerType)
        let endpoint address = new ServiceEndpoint(routerContract, createBinding(), new EndpointAddress(address))

        let serviceEndpoints = [| endpoint serviceAddress |]
        let configuration = new RoutingConfiguration()
        configuration.FilterTable.Add(new MatchAllMessageFilter(), serviceEndpoints)

        let host = new ServiceHost(typeof<RoutingService>)
        ignore <| host.AddServiceEndpoint(routerType, createBinding(), routerAddress)
        host.Description.Behaviors.Add(new RoutingBehavior(configuration))
        host        

    [<EntryPoint>]
    let main(args) =

        let (routerAddress, serviceAddress) =
            match args with
            | [| ra; sa |] -> (ra, sa)
            | _ -> ("net.tcp://localhost:4508/", "net.tcp://remotehost:4508/")

        let netTcp() = new NetTcpBinding(SecurityMode.None)
        let mexTcp() = MetadataExchangeBindings.CreateMexTcpBinding()

        let tcpRouter = createSimpleRouter netTcp  routerAddress           serviceAddress
        let mexRouter = createSimpleRouter mexTcp (routerAddress + "mex") (serviceAddress + "mex")

        tcpRouter.Open()
        mexRouter.Open()

        Console.WriteLine("routing ...\n{0} <-> R:{1}", serviceAddress, routerAddress)

        ignore <| Console.ReadKey true
