WCF技术剖析 Two

WCF终结点和寻址之--AddressHead信息匹配代码

Contracts契约

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

 namespace Artech.WcfServices.Contracts
 {
     [ServiceContract(Name="CalculatorService",Namespace="http://www.artech.com/")]
     public interface ICalculator
     {

         [OperationContract]
         double Add(double x, double y);

         [OperationContract]
         double Subtract(double x, double y);

         [OperationContract]
         double Multiply(double x, double y);

         [OperationContract]
         double Divide(double x, double y);
     }
 }

Services服务，

完全匹配属性：[ServiceBehavior(AddressFilterMode=AddressFilterMode.Any)]

 using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Text;
 using Artech.WcfServices.Contracts;
 using System.ServiceModel;

 namespace Artech.WcfServices.Services
 {
     [ServiceBehavior(AddressFilterMode=AddressFilterMode.Any)]
     public class CalculatorService : ICalculator
     {
         public double Add(double x, double y)
         {
             return x + y;
         }

         public double Subtract(double x, double y)
         {
             return x - y;
         }

         public double Multiply(double x, double y)
         {
             return x * y;
         }

         public double Divide(double x, double y)
         {
             return x / y;
         }
     }
 }

Hosting主机注册，

需要匹配的信息

string headevalue = "licensed user";
string headerNmae = "userType";
string headNamespace = "http://www.artech.com/";

 using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Text;
 using System.ServiceModel;
 using System.ServiceModel.Description;
 using Artech.WcfServices.Contracts;
 using Artech.WcfServices.Services;
 using System.ServiceModel.Channels;

 namespace Artech.WcfServices.Hosting
 {
     class Program
     {
         static void Main(string[] args)
         {
             using (ServiceHost servicehost = new ServiceHost(typeof(CalculatorService),
                 new Uri("http://127.0.0.1:9999/CalculatorService")))
             {
                 string headevalue = "licensed user";
                 string headerNmae = "userType";
                 string headNamespace = "http://www.artech.com/";

                 AddressHeader header = AddressHeader.CreateAddressHeader(headerNmae, headNamespace, headevalue);

                 EndpointAddress endpointAddress = new EndpointAddress
                     (new Uri("http://127.0.0.1:9999/CalculatorService"), header);

                 ServiceEndpoint serviceEndpoint = new ServiceEndpoint(ContractDescription.GetContract(typeof(ICalculator)), new
                 WSHttpBinding(), endpointAddress);

                 servicehost.Description.Endpoints.Add(serviceEndpoint);

                 ServiceMetadataBehavior behavior = new ServiceMetadataBehavior();
                 behavior.HttpGetEnabled = true;
                 servicehost.Description.Behaviors.Add(behavior);

                 servicehost.Opened += delegate
                 {
                     Console.WriteLine("Service begin to listen via the Address:{0}",
             servicehost.BaseAddresses[].ToString());
                 };

                 servicehost.Open();

                 Console.ReadLine();

             }

         }
     }
 }

客户端调用

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <client>
      <endpoint name="CalculatorService" address="http://127.0.1.1:9999/CalculatorService" binding ="wsHttpBinding"
                contract="Artech.WcfServices.Contracts.ICalculator" >
        <headers>
          <userType xmlns="http://www.artech.com/">chenJian</userType>
        </headers>
      </endpoint>
    </client>
  </system.serviceModel>
</configuration>

客户端-App.Config配置

 using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Text;
 using Artech.WcfServices.Contracts;
 using System.ServiceModel;
 using System.ServiceModel.Channels;

 namespace ClientConsole
 {

         static void Main(string[] args)
         {
             using (ChannelFactory<ICalculator> channelFactory = new
                 ChannelFactory<ICalculator>("CalculatorService"))
             {
                 ICalculator proxy = channelFactory.CreateChannel();
                 using (proxy as IDisposable)
                 {
                    Console.WriteLine("x+y={0}", proxy.Add(, ));
                     Console.WriteLine("x-y={0}", proxy.Subtract(, ));

                     Console.ReadLine();

                 }
             }
         }
