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
