記錄：Web無引用無配置方式動態調用WCF服務

       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，之前也用過JQuery直接調用Wcf的，可是說實話真的忘了…

       因此此次解決完仍是花幾分鐘記錄一下

 

       WCF服務端：宿主在現有Win服務中，在服務啓動時添加代碼 ，服務代碼就不用寫了，接口和實現按照契約實現便可

            
 　　        private ServiceHost serviceHost = null; //服務宿主

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

 

      服務端ServiceModel配置：我的感受也是最麻煩的地方，WCF自己支持多種通訊方式，因此配置較多，不過基本瞭解後也差很少

        <endpoint address=""

                  contract="命名空間+接口名" />
        <!-- the mex endpoint is exposed at http://localhost:8000/ServiceModel/service/mex -->
        <endpoint address="mex"
                  binding="mexHttpBinding"

        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

 啓動完後可訪問：http://localhost:8000/ServiceModel/service.svc 查看以下圖：

 

   客戶端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;
                }
            }
        }
    }
}

 

因爲是動態調用的，因此沒有任何配置，能夠向下邊這樣直接使用：

        WSHttpBinding bind = new WSHttpBinding();//重點這兒，能夠傳遞不一樣的Bind，和對應的服務端配置參數（若是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() 便可，這裏我使用的WSHttpBinding

若是有想了解JQuery調用WCF的方式請參考站長的博客：http://www.cnblogs.com/dudu/archive/2009/07/14/1523082.html

 

注意：若是碰到 "響應消息的內容類型 text/html; charset=utf-8 與綁定(text/xml; charset=utf-8)的內容類型不匹配。" 

也有多是Bind的方式不匹配，另外Host裏的地址儘可能用IP地址來綁定

 

"響應消息的內容類型 text/html; charset=utf-8 與綁定(text/xml; charset=utf-8)的內容類型不匹配。"問題的解決辦法
