这几年一直用WebApi较多，最近项目中有个需求比较适合使用WCF，以前也用过JQuery直接调用Wcf的，但是说实话真的忘了…

所以这次解决完还是花几分钟记录一下

WCF服务端：宿主在现有Win服务中，在服务启动时添加代码，服务代码就不用写了，接口和实现按照契约实现即可

 　　        private ServiceHost serviceHost = null; //服务宿主

　　 　　　　 //启动WCF服务

            if (serviceHost != null)

            {

                serviceHost.Close();

            }

            serviceHost = new ServiceHost(typeof(ControlService));

            serviceHost.Open();

            Toolkit.Log.Warn("WCF服务启动");

服务端ServiceModel配置：个人感觉也是最麻烦的地方，WCF本身支持多种通信方式，所以配置较多，不过基本了解后也差不多

详细可参考：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 . -->

      <service name="命名空间+类名"

               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="命名空间+接口名" />

        <!-- 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>

启动完后可访问：http://localhost:8000/ServiceModel/service.svc 查看如下图：

客户端WCF服务调用封装：

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;

                }

            }

        }

    }

}

由于是动态调用的，所以没有任何配置，可以向下边这样直接使用：

        WSHttpBinding bind = new WSHttpBinding();//重点这儿，可以传递不同的Bind，和对应的服务端配置参数（如果参数和服务端不一致则会报错）

        WCFHelper.ExecuteMethod<IControlService>(bind,"http://localhost:8000/ServiceModel/service.svc", "ResetTerminal", new object[] { "参数" });

注意第一个参数需根据对应的WCF服务端配置对应

例如服务端是webHttpBinding，这儿也换成webHttpBinding bind=new webHttpBinding() 即可，这里我使用的WSHttpBinding

如果有想了解JQuery调用WCF的方式请参考站长的博客：http://www.cnblogs.com/dudu/archive/2009/07/14/1523082.html

注意：如果碰到 "响应消息的内容类型 text/html; charset=utf-8 与绑定(text/xml; charset=utf-8)的内容类型不匹配。"

也有可能是Bind的方式不匹配，另外Host里的地址尽量用IP地址来绑定

xml; charset=utf-8)的内容类型不匹配。"问题的解决办法

记录：Web无引用无配置方式动态调用WCF服务

"响应消息的内容类型 text/html; charset=utf-8 与绑定(text/xml; charset=utf-8)的内容类型不匹配。"问题的解决办法
