（2）WCF客户端调用

一、visual studion引用生成代理

引入服务端发布元数据的地址（并不是服务的地址）

用服务端是控制台程序

例子1

服务端的配置

  <system.serviceModel>
    <services>
      <service name="WcfServiceLibrary6.Service1" behaviorConfiguration="HelloServiceBehavior">
        <!--host这段可以测试时启动wcf测试客户端，运行后除了弹出测试客户端，也可以在浏览器中用此address访问-->
        <host>
          <baseAddresses>
            <add baseAddress = "http://localhost:8733/" />
          </baseAddresses>
        </host>
        <endpoint address="" binding="basicHttpBinding" contract="WcfServiceLibrary6.IService1" />
      </service>
    </services>
    <!--元数据-->
    <behaviors>
      <serviceBehaviors >
        <behavior name="HelloServiceBehavior">
          <serviceMetadata httpGetEnabled="True"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

用右键添加服务引用的方式

最后在客户端配置文件会自动添加xml

    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="BasicHttpBinding_IService1" />
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://localhost:8733/" binding="basicHttpBinding"
                bindingConfiguration="BasicHttpBinding_IService1" contract="ServiceReference1.IService1"
                name="BasicHttpBinding_IService1" />
        </client>
    </system.serviceModel>

例子2

把例子1的服务端终结点添加一个address属性

<endpoint address="Service1" binding="basicHttpBinding" contract="WcfServiceLibrary6.IService1" />

客户端还是引用 http://localhost:8733/

生成xml，发现地址多出了一个Service1

例子3

把例子1的服务端终结点添加一个address属性

<endpoint address="http://localhost:22222/" binding="basicHttpBinding" contract="WcfServiceLibrary6.IService1" />

客户端引用依然是  http://localhost:8733/

生成xml，生成的地址变成了终结点的地址

    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="BasicHttpBinding_IService1" />
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://localhost:22222/" binding="basicHttpBinding"
                bindingConfiguration="BasicHttpBinding_IService1" contract="ServiceReference1.IService1"
                name="BasicHttpBinding_IService1" />
        </client>
    </system.serviceModel>

例4

使用tcp部署服务端

  <system.serviceModel>
    <services>
      <service name="WcfServiceLibrary6.Service1" behaviorConfiguration="HelloServiceBehavior">
        <!--host这段可以测试时启动wcf测试客户端，运行后除了弹出测试客户端，也可以在浏览器中用此address访问-->
        <host>
          <baseAddresses>
            <add baseAddress = "net.tcp://localhost:8733/" />
          </baseAddresses>
        </host>
        <endpoint address="net.tcp://localhost:22222/" binding="netTcpBinding" contract="WcfServiceLibrary6.IService1" />
        <endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" />
      </service>
    </services>
    <!--元数据-->
    <behaviors>
      <serviceBehaviors >
        <behavior name="HelloServiceBehavior">
          <serviceMetadata />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

客户端引用

生成

    <system.serviceModel>
        <bindings>
            <netTcpBinding>
                <binding name="NetTcpBinding_IService1" />
            </netTcpBinding>
        </bindings>
        <client>
            <endpoint address="net.tcp://localhost:22222/" binding="netTcpBinding"
                bindingConfiguration="NetTcpBinding_IService1" contract="ServiceReference1.IService1"
                name="NetTcpBinding_IService1">
                <identity>
                    <userPrincipalName value="XTZ-01805141702\Administrator" />
                </identity>
            </endpoint>
        </client>
    </system.serviceModel>

二、使用SvcUtil生成代理

假设有服务端配置

契约

    [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        string GetData(int value);
    }

    public class Service1 : IService1
    {
        public string GetData(int value)
        {
            return string.Format("You entered: {0}", value);
        }
    }

服务端控制台

static void Main(string[] args)
        {
            Uri httpBaseAddress = new Uri("http://localhost:9001/");
            Uri tcpBaseAddress = new Uri("net.tcp://localhost:9002/");

            ServiceHost host = new ServiceHost(typeof(Service1), httpBaseAddress, tcpBaseAddress);

            ////启动行为
            ServiceMetadataBehavior smb = host.Description.Behaviors.Find<ServiceMetadataBehavior>();
            if (smb == null)
            {
                smb = new ServiceMetadataBehavior();
            }
            smb.HttpGetEnabled = true;
            host.Description.Behaviors.Add(smb);
            host.Open();
            Console.WriteLine("Service已经启动，按任意键终止服务！");
            Console.Read();
            host.Close();
        }

使用工具生成代理

在C盘 SvcUtil.exe 能搜索到此工具

把它拷贝到一个单独的文件夹，用cmd指令进入该目录。这里我考到了h盘的根目录下

SvcUtil http://localhost:9001 /out:proxy.cs

生成 二个文件 output.config和proxy.cs

output.config

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="BasicHttpBinding_IService1" />
            </basicHttpBinding>
            <netTcpBinding>
                <binding name="NetTcpBinding_IService1" />
            </netTcpBinding>
        </bindings>
        <client>
            <endpoint address="http://localhost:9001/" binding="basicHttpBinding"
                bindingConfiguration="BasicHttpBinding_IService1" contract="IService1"
                name="BasicHttpBinding_IService1" />
            <endpoint address="net.tcp://localhost:9002/" binding="netTcpBinding"
                bindingConfiguration="NetTcpBinding_IService1" contract="IService1"
                name="NetTcpBinding_IService1">
                <identity>
                    <userPrincipalName value="XTZ-01805141702\Administrator" />
                </identity>
            </endpoint>
        </client>
    </system.serviceModel>
</configuration>

proxy.cs

[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")]
[System.ServiceModel.ServiceContractAttribute(ConfigurationName="IService1")]
public interface IService1
{

    [System.ServiceModel.OperationContractAttribute(Action="http://tempuri.org/IService1/GetData", ReplyAction="http://tempuri.org/IService1/GetDataResponse")]
    string GetData(int value);

    [System.ServiceModel.OperationContractAttribute(Action="http://tempuri.org/IService1/GetData", ReplyAction="http://tempuri.org/IService1/GetDataResponse")]
    System.Threading.Tasks.Task<string> GetDataAsync(int value);
}

[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")]
public interface IService1Channel : IService1, System.ServiceModel.IClientChannel
{
}

[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")]
public partial class Service1Client : System.ServiceModel.ClientBase<IService1>, IService1
{

    public Service1Client()
    {
    }

    public Service1Client(string endpointConfigurationName) :
            base(endpointConfigurationName)
    {
    }

    public Service1Client(string endpointConfigurationName, string remoteAddress) :
            base(endpointConfigurationName, remoteAddress)
    {
    }

    public Service1Client(string endpointConfigurationName, System.ServiceModel.EndpointAddress remoteAddress) :
            base(endpointConfigurationName, remoteAddress)
    {
    }

    public Service1Client(System.ServiceModel.Channels.Binding binding, System.ServiceModel.EndpointAddress remoteAddress) :
            base(binding, remoteAddress)
    {
    }

    public string GetData(int value)
    {
        return base.Channel.GetData(value);
    }

    public System.Threading.Tasks.Task<string> GetDataAsync(int value)
    {
        return base.Channel.GetDataAsync(value);
    }
}

config文件尽量自己手写，不用自动生成的，终结要有名字。

三 编写客户端

以下客户端的服务端应用的是 “标题二”下的契约和服务

（1）使用工具代理文件编程

创建一个控制台，output.config文件的内容复制到控制台下的app.config,再把生成的代理文件复制到控制台下

Program.cs

    class Program
    {
        static void Main(string[] args)
        {
            Service1Client proxy = new Service1Client("BasicHttpBinding_IService1");//传入客户端终结点名称
            string str=proxy.GetData();
            proxy.Close();
            Console.Write(str);
            Console.ReadKey();
        }
    }

运行

（2）引用方式编程

客户端引用后的xml

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup>
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6" />
    </startup>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="BasicHttpBinding_IService1" />
            </basicHttpBinding>
            <netTcpBinding>
                <binding name="NetTcpBinding_IService1" />
            </netTcpBinding>
        </bindings>
        <client>
            <endpoint address="http://localhost:9001/" binding="basicHttpBinding"
                bindingConfiguration="BasicHttpBinding_IService1" contract="ServiceReference1.IService1"
                name="BasicHttpBinding_IService1" />
            <endpoint address="net.tcp://localhost:9002/" binding="netTcpBinding"
                bindingConfiguration="NetTcpBinding_IService1" contract="ServiceReference1.IService1"
                name="NetTcpBinding_IService1">
                <identity>
                    <userPrincipalName value="XTZ-01805141702\Administrator" />
                </identity>
            </endpoint>
        </client>
    </system.serviceModel>
</configuration>

    class Program
    {
        static void Main(string[] args)
        {
            var client = new ServiceReference1.Service1Client("BasicHttpBinding_IService1");//使用http通讯
            //var client = new ServiceReference1.Service1Client("NetTcpBinding_IService1");//使用tcp通讯
            string str = client.GetData();
            client.Close();
            Console.Write(str);
            Console.ReadKey();
        }
    }
