化零为整WCF(3) - 绑定Binding(basicHttpBinding和netTcpBinding)

作者： webabcd


介绍
WCF(Windows Communication Foundation) - 绑定Binding：Http以basicHttpBinding为例，Tcp以netTcpBinding为例。


示例
1、服务
IHello.cs

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

using  System.ServiceModel;

namespace  WCF.ServiceLib.Binding
{
    /**//// <summary>
    /// IHello接口
    /// </summary>
    [ServiceContract]
    public interface IHello
    {
        /**//// <summary>
        /// 打招呼方法
        /// </summary>
        /// <param name="name">人名</param>
        /// <returns></returns>
        [OperationContract]
        string SayHello(string name);
    }
}

Hello.cs

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

using  System.ServiceModel;

namespace  WCF.ServiceLib.Binding
{
    /**//// <summary>
    /// Hello类
    /// </summary>
    public class Hello : IHello
    {
        /**//// <summary>
        /// 打招呼方法
        /// </summary>
        /// <param name="name">人名</param>
        /// <returns></returns>
        public string SayHello(string name)
        {
            return "Hello: " + name;
        }
    }
}

2、宿主
Hello.cs

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

using  System.ServiceModel;

namespace  WCF.ServiceHost2.Binding
{
    class Hello
    {
        static void Main(string[] args)
        {
            using (ServiceHost host = new ServiceHost(typeof(WCF.ServiceLib.Binding.Hello)))
            {
                // 写代码的方式做host
                // host.AddServiceEndpoint(typeof(WCF.ServiceLib.Binding.IHello), new NetTcpBinding(), "net.tcp://localhost:54321/Binding/Hello");
                host.Open();

                Console.WriteLine("服务已启动");
                Console.WriteLine("按<ENTER>停止服务");
                Console.ReadLine();
            }
        }
    }
}

App.config

<? xml version="1.0" encoding="utf-8"  ?>
< configuration >
   < system.serviceModel >
     < services >
       <!-- name - 提供服务的类名 -->
       <!-- behaviorConfiguration - 指定相关的行为配置 -->
       < service  name ="WCF.ServiceLib.Binding.Hello"  behaviorConfiguration ="BindingBehavior" >
         <!-- address - 服务地址 -->
         <!-- binding - 通信方式 -->
         <!-- contract - 服务契约 -->
         <!-- <endpoint binding="basicHttpBinding" contract="WCF.ServiceLib.Binding.IHello" address="Hello" /> -->
         < endpoint  binding ="netTcpBinding"  contract ="WCF.ServiceLib.Binding.IHello"  address ="net.tcp://localhost:54321/Binding/Hello"   />
         <!-- 元数据交换的endpoint -->
         <!-- 注：address是mex，它会和host/baseAddresses节点中的baseAddress做拼接，即提供元数据交换的地址为：http://localhost:12345/Binding/mex -->
         < endpoint  binding ="mexHttpBinding"  contract ="IMetadataExchange"  address ="mex"   />
         < host >
           < baseAddresses >
             < add  baseAddress ="http://localhost:12345/Binding/" />
           </ baseAddresses >
         </ host >
       </ service >
     </ services >
     < behaviors >
       < serviceBehaviors >
         < behavior  name ="BindingBehavior" >
           <!-- httpGetEnabled - 使用get方式提供服务 -->
           < serviceMetadata  httpGetEnabled ="true"   />
         </ behavior >
       </ serviceBehaviors >
     </ behaviors >
   </ system.serviceModel >
</ configuration >

3、客户端
Hello.cs

using  System;
using  System.Collections.Generic;
using  System.ComponentModel;
using  System.Data;
using  System.Drawing;
using  System.Linq;
using  System.Text;
using  System.Windows.Forms;

using  System.ServiceModel;

namespace  Client2.Binding
{
    public partial class Hello : Form
    {
        public Hello()
        {
            InitializeComponent();
        }

        private void btnSayHello_Click(object sender, EventArgs e)
        {
            // 写代码的方式做client
            // IHello proxy = ChannelFactory<IHello>.CreateChannel(new NetTcpBinding(), new EndpointAddress("net.tcp://localhost:54321/Binding/Hello"));

            Binding.HelloClient proxy = new Binding.HelloClient();

            MessageBox.Show(proxy.SayHello(txtName.Text));

            proxy.Close();
        }
    }
}

App.config

<? xml version="1.0" encoding="utf-8"  ?>
< configuration >
   < system.serviceModel >
     < client >
       <!-- address - 服务地址 -->
       <!-- binding - 通信方式 -->
       <!-- contract - 服务契约 -->
       <!-- <endpoint address="http://localhost:12345/Binding/Hello" binding="basicHttpBinding" contract="Binding.IHello" /> -->
       < endpoint  address ="net.tcp://localhost:54321/Binding/Hello"  binding ="netTcpBinding"  contract ="Binding.IHello"   />
     </ client >
   </ system.serviceModel >
</ configuration >

运行结果：
单击"Hello"按钮后弹出提示框，显示"Hello: webabcd"


OK
