Jquery对WCF的Ajax调用在Firefox中不起作用

嗨，我做了一个WCF服务，可以从Jquery访问它在IE8中工作，但在firefox中不工作

这是我的服务课

namespace JSONSample
{
    [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        [WebGet( ResponseFormat = WebMessageFormat.Json)]
        Employee[] getData();
    }

    [DataContract]
    public class Employee
    {
        [DataMember]
        public string id { get; set; }

        [DataMember]
        public string name { get; set; }
    }

}

以及实施情况

namespace JSONSample
{

    public class Service1 : IService1
    {

        #region IService1 Members

        public Employee[] getData()
        {
            return new Employee[] { new Employee() { id = "1", name = "John" }, new Employee() { id = "2", name = "Bourne" }, new Employee() { id = "3", name = "Harry" } };
        }

        #endregion
    }
}

Webconfig中的端点

我已经创建了端点

<system.serviceModel>
        <behaviors>
            <serviceBehaviors>
                <behavior name="JSONSample.Service1Behavior">
                    <serviceMetadata httpGetEnabled="true"/>
                    <serviceDebug includeExceptionDetailInFaults="false"/>
                </behavior>
            </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="web">
          <webHttp/>
        </behavior>
      </endpointBehaviors>
        </behaviors>
    <services>
      <service behaviorConfiguration="JSONSample.Service1Behavior" name="JSONSample.Service1">
        <endpoint address="" binding="webHttpBinding" contract="JSONSample.IService1" behaviorConfiguration="web"/>
      </service>
    </services>
    </system.serviceModel>

为什么这只适用于IE而不适用于firefox？您还必须在WCF服务中设置CORS头。您可以通过自定义行为轻松设置

检查这个。

你应该考虑使用ASP.NET的MVC3操作和JSORMEST…或MVC4WebAPI。

jQuery.support.cors = true;
        $(document).ready(function() {

            $.ajax({
                 type: "GET", 
                 url: "http://localhost:51220/Service1.svc/getdata", 
                 contentType: "application/json; charset=utf-8", 
                 dataType: "json", 
                 processdata: false,
                 success: function(msg) {
                        alert(msg);
                 },
                 error: function ServiceFailed(result) {
                    alert('Service call failed: ' + result.status + '' + result.statusText);
                }
            });


        });
