创建WCF服务

1.定义WCF服务协定

[ServiceContract]
    public interface IUser
    {
        [OperationContract]
        string ShowName(string name);
    }

2.实现WCF服务协定

public class User : IUser
    {
        public string ShowName(string name)
        {
            string wcfName = string.Format("Show name：{0}", name);
            return wcfName;
        }
    }

3.承载并运行WCF服务

　　3.1 创建URL基地址

Uri baseAddress = new Uri("http://localhost:8080/User");

　　3.2 创建ServiceHost示例来承载Service

ServiceHost serviceHost = new ServiceHost(typeof(User),baseAddresses);

　　3.3 创建ServiceEndpoint示例

host.AddServiceEndpoint(typeof(IUser), new WSHttpBinding(), "User");

　　3.4 开启元数据交换

//将HttpGetEnabled属性设置为true
ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
smb.HttpGetEnabled = true;
//将行为添加到Behaviors中
host.Description.Behaviors.Add(smb);

　　3.5 开启ServierHost以监听消息

//打开宿主
host.Open();

(也可以在server的app.config中配置)

ServiceHost host = new ServiceHost(typeof(User));
host.Open();

 

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <services>
      <service name="WcfServiceLibrary.User">
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8080/User"/>
          </baseAddresses>
        </host>
        <endpoint address="" binding="wsHttpBinding" contract="WcfServiceLibrary.IUser"></endpoint>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="True"/>
          <serviceDebug includeExceptionDetailInFaults="False"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

 

4.创建WCF客户端

　　4.1添加Service Reference,address为server中的baseaddress

　　4.2调用服务协定(Service contract)

5.Config WCF client

在client中的app.config配置

<system.serviceModel>
    <bindings>
      <wsHttpBinding>
        <binding name="WSHttpBinding_IUser" />
      </wsHttpBinding>
    </bindings>
    <client>
      <endpoint address="http://localhost:8080/User" binding="wsHttpBinding"
        bindingConfiguration="WSHttpBinding_IUser" contract="ServiceReference.IUser"
        name="WSHttpBinding_IUser">
        <identity>
          <userPrincipalName value="xxxx" />
        </identity>
      </endpoint>
    </client>
 </system.serviceModel>
