       這幾年一直用WebApi較多，最近項目中有個需求比較適合使用WCF，以前也用過JQuery直接調用Wcf的，但是說實話真的忘了…

       所以這次解決完還是花幾分鐘記錄一下

 

       WCF服務端：宿主在現有Win服務中，在服務啟動時添加代碼 ，服務代碼就不用寫了，介面和實現按照契約實現即可

            
 　　        private ServiceHost serviceHost = null; //服務宿主

　　 　　　　 //啟動WCF服務            if (serviceHost != null)            {                serviceHost.Close();                    }            serviceHost = new ServiceHost(typeof(ControlService));            serviceHost.Open();            Toolkit.Log.Warn("WCF服務啟動");

 

      服務端ServiceModel配置：個人感覺也是最麻煩的地方，WCF本身支援多種通訊方式，所以配置較多，不過基本瞭解後也差不多

      詳細可參考：http://www.cnblogs.com/ingstyle/p/5711249.html

<?xml version="1.0" encoding="utf-8" ?><configuration>  <system.serviceModel>    <services>      <!-- This section is optional with the new configuration model           introduced in .NET Framework 4. -->      <service name="命名空間+類名"               behaviorConfiguration="ControlServiceBehavior">        <host>          <baseAddresses>            <add baseAddress="http://localhost:8000/ServiceModel/service.svc"/>          </baseAddresses>        </host>        <!-- this endpoint is exposed at the base address provided by host: http://localhost:8000/ServiceModel/service  -->        <endpoint address=""                  binding="wsHttpBinding"                   contract="命名空間+介面名" />        <!-- the mex endpoint is exposed at http://localhost:8000/ServiceModel/service/mex -->        <endpoint address="mex"                  binding="mexHttpBinding"                  contract="IMetadataExchange" />      </service>    </services>    <behaviors>      <serviceBehaviors>        <behavior name="ControlServiceBehavior">          <serviceMetadata httpGetEnabled="true"/>          <serviceDebug includeExceptionDetailInFaults="False"/>        </behavior>      </serviceBehaviors>    </behaviors>  </system.serviceModel></configuration>

 

 啟動完後可訪問：http://localhost:8000/ServiceModel/service.svc 查看如：

 

   用戶端WCF服務調用封裝：

public class WCFHelper{    public WCFHelper()    {    }    public static object ExecuteMethod<T>(Binding bind, string pUrl, string pMethodName, params object[] pParams)    {        EndpointAddress address = new EndpointAddress(pUrl);        Binding bindinginstance = null;        bindinginstance = bind;        using (ChannelFactory<T> channel = new ChannelFactory<T>(bindinginstance, address))        {            T instance = channel.CreateChannel();            using (instance as IDisposable)            {                try                {                    Type type = typeof(T);                    MethodInfo mi = type.GetMethod(pMethodName);                    return mi.Invoke(instance, pParams);                }                catch (TimeoutException)                {                    (instance as ICommunicationObject).Abort();                    throw;                }                catch (CommunicationException)                {                    (instance as ICommunicationObject).Abort();                    throw;                }                catch (Exception vErr)                {                    (instance as ICommunicationObject).Abort();                    throw;                }            }        }    }}

 

由於是動態調用的，所以沒有任何配置，可以向下邊這樣直接使用：

        WSHttpBinding bind = new WSHttpBinding();//重點這兒，可以傳遞不同的Bind，和對應的服務端配置參數（如果參數和服務端不一致則會報錯）        WCFHelper.ExecuteMethod<IControlService>(bind,"http://localhost:8000/ServiceModel/service.svc", "ResetTerminal", new object[] { "參數" });

注意第一個參數需根據對應的WCF服務端配置對應

例如服務端是webHttpBinding，這兒也換成webHttpBinding bind=new webHttpBinding() 即可，這裡我使用的WSHttpBinding

如果有想瞭解JQuery調用WCF的方式請參考站長的部落格：http://www.cnblogs.com/dudu/archive/2009/07/14/1523082.html
