jQuery调用WCF

 1. 添加System.ServiceModel和System.ServiceModel.Web的引用

 2.

//契约
    [ServiceContract]
    public interface IService1
    {
        //[WebGet] //WebGet与WebInvoke冲突，只能使用一个
        [OperationContract]        
        [WebInvoke(RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest,Method="GET")]
        string DoWork();
    }

//实现
//Service1.svc.cs
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class Service1 : IService1
    {
        public string DoWork()
        {
            return System.DateTime.Now.ToString();
        }
    }

 <behaviors>
   <serviceBehaviors>
    <behavior name="WebApplication1.Service1Behavior">
     <serviceMetadata httpGetEnabled="true" />
     <serviceDebug includeExceptionDetailInFaults="false" />            
    </behavior>
   </serviceBehaviors>

    <endpointBehaviors>
      <behavior name="DiggServiceBehavior">
        <enableWebScript/><!--impont-->
      </behavior>   
    </endpointBehaviors>
  </behaviors>
   
   
  <services>
   <service behaviorConfiguration="WebApplication1.Service1Behavior"
    name="WebApplication1.Service1">
    <!--只能使用webHttpBinding-->
    <endpoint address="" binding="webHttpBinding" contract="WebApplication1.IService1" behaviorConfiguration="DiggServiceBehavior">
     <identity>
      <dns value="localhost" />
     </identity>
    </endpoint>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
   </service>
  </services>

调用

  <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.3/jquery.min.js" type="text/javascript"></script>
        <script language="javascript" type="text/jscript">
            $.ajax({
                url: "Service1.svc/dowork",
                type: "POST",
                context: document.body,
                contentType: 'application/json; charset=utf8',
                success: function(data) {
                    alert("ok:" + data);
                },
                error: function(xhr) {
                    alert("err:" + xhr.responseText);
                }
            });
        </script>
