WCF 路由功能

最近项目使用到点WCF功能，路由服务,重要还是配置文件App.config

 

Routing服务代码

using System.Text;
using System.ServiceModel;
using System.ServiceModel.Routing;

namespace RoutingServer
{
    class RoutingServer
    {
        static void Main(string[] args)
        {
            using (ServiceHost host = new ServiceHost(typeof(RoutingService)))
            {
                host.Opened  = (s, e) => {
                    Console.ForegroundColor = ConsoleColor.Yellow;
                    Console.WriteLine("Routing...");
                };
                host.Open();

                Console.ReadKey();
            }
        }
    }
}

Routing中的App.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    
    <services>
      <service name="System.ServiceModel.Routing.RoutingService" behaviorConfiguration="RoutingBehaviors">
        <endpoint name="DuplexSessionRouter" address="" binding="netTcpBinding" contract="System.ServiceModel.Routing.IRequestReplyRouter" bindingConfiguration="abc"/>
<!--使用的是EndpointName-->

        <endpoint name="DB" address="DB" binding="netTcpBinding" contract="System.ServiceModel.Routing.IRequestReplyRouter" bindingConfiguration="abc"/>
        <host>
          <baseAddresses>
            <add baseAddress="http://192.168.1.200:9001"/>
            <add baseAddress="net.tcp://192.168.1.200:9002/V1/Routing"/>
          </baseAddresses>
        </host>
      </service>
    </services>
    
    <behaviors>
      <serviceBehaviors>
        <behavior name="RoutingBehaviors">
          <serviceDebug includeExceptionDetailInFaults="true"/>
          <serviceMetadata httpGetEnabled="true"/>
          <routing filterTableName="FilterTable1"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    
    <bindings>
      <netTcpBinding>
        <binding name="abc">
          <security mode="None"></security>
        </binding>
      </netTcpBinding>
    </bindings>

    <routing>
      <filterTables>
        <filterTable name="FilterTable1">
<!--backupList :备份-->

          <add endpointName="TestEndpoint" filterName="FilterTest" backupList="backupA"/>
        </filterTable>
      </filterTables>

      <filters>
        <filter name="FilterTest" filterType="EndpointName" filterData="DB" />
      </filters>
      <backupLists>
        <backupList name="backupA">
          <add endpointName="BackupServerA" />
        </backupList>
      </backupLists>
    </routing>

    <client>
      <endpoint address="net.tcp://192.168.1.200:8002/V1" binding="netTcpBinding" contract="*" bindingConfiguration="abc" name="TestEndpoint"/>

      <endpoint address="net.tcp://192.168.1.200:6001/V1" binding="netTcpBinding" contract="*" bindingConfiguration="abc" name="BackupServerA"/>
    </client>
    
  </system.serviceModel>
</configuration>

8002端口中代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;

namespace ServerA
{
    class Program
    {
        static void Main(string[] args)
        {
            using (ServiceHost host = new ServiceHost(typeof(AServer)))
            {
                host.Opened  = (s, e) =>
                {
                    Console.ForegroundColor = ConsoleColor.Yellow;
                    Console.WriteLine("server A...");
                };
                host.Open();

                Console.ReadKey();
            }
        }
    }
    [ServiceContract(SessionMode= SessionMode.Required)]
    public interface IAServer
    {
        [OperationContract]
        string Send();
    }

    public class AServer : IAServer
    {
        public string Send()
        {
            return "Hello world";
        }
    }
}

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <services>
      <service name="ServerA.AServer" behaviorConfiguration="AServerBehavior">
        <endpoint address="" binding="netTcpBinding" contract="ServerA.IAServer" bindingConfiguration="TcpBinding"/>
        <host>
          <baseAddresses>
            <add baseAddress="http://192.168.1.200:8000"/>
            <add baseAddress="net.tcp://192.168.1.200:8002/V1"/>
          </baseAddresses>
        </host>
      </service>
    </services>

    <bindings>
      <netTcpBinding>
        <binding name="TcpBinding">
          <security mode="None"></security>
        </binding>
      </netTcpBinding>
    </bindings>

    <behaviors>
      <serviceBehaviors >
        <behavior name="AServerBehavior">
          <serviceDebug includeExceptionDetailInFaults="true"/>
          <serviceMetadata httpGetEnabled="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    
  </system.serviceModel>
</configuration>

backupList中代码跟这8002端口代码一样。

 

使用Svcutil.exe生成客户端代码

svcutil.exe /out:c:\Routing.cs /config:C:\app.config http://192.168.1.200:9001

svcutil.exe /out:C:\Test.cs /config:c:\app2.config http://192.168.1.200:8000

然后复制app.config跟Test.cs到客户端调用工程里。

客户端演示

一定要修改App.config里的

<endpoint address="net.tcp://192.168.1.200:9002/V1/Routing/DB" binding="netTcpBinding"
               bindingConfiguration="DuplexSessionRouter" contract="IAServer"
               name="DB" />
