Jquery Ajax調用WCF不工作在Firefox

Question

您好我做了一個WCF服務從Jquery訪問它在IE 8，IE中工作，但它不工作在Firefox。

這是我的服務類

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; } 
    } 

} 

而實施Webconfig

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 
    } 
} 

端點我創建了終點

<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> 

從通話HTML我使用的是GET和任何數據未發送到服務器

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); 
       } 
      }); 


     }); 

這是爲什麼僅工作在IE和Firefox的不

你必須設置在WCF服務的CORS頭了。您可以通過自定義行爲輕鬆設置。
