Angular.js - CORS - ASP. NET - Rest API -在Access-Control-All

目前正在一个网页上工作，它调用了一个rest api，它击中了我的SQL服务器。在VS2013的本地主机上工作，但是当发布并添加到服务器时，我开始遇到CORS问题。我已经添加了以下代码到我的网页。我的web服务的配置文件，仍然没有运气:

<httpProtocol>
  <customHeaders>
    <add name="Access-Control-Allow-Origin" value="*" />
    <add name="Access-Control-Allow-Methods" value="GET" />
    <add name="Access-Control-Allow-Headers" value="Content-Type" />
  </customHeaders>
</httpProtocol>

启用Cors后，我的webapiconfig.cs是这样的:

 public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        config.EnableCors();
        var json = config.Formatters.JsonFormatter;
        json.SerializerSettings.PreserveReferencesHandling = Newtonsoft.Json.PreserveReferencesHandling.Objects;
        json.SerializerSettings.ContractResolver = new
            CamelCasePropertyNamesContractResolver();
        config.Formatters.Remove(config.Formatters.XmlFormatter);
        // Web API configuration and services
        // Configure Web API to use only bearer token authentication.
        config.SuppressDefaultHostAuthentication();
        config.Filters.Add(new HostAuthenticationFilter(OAuthDefaults.AuthenticationType));
        // Web API routes
        config.MapHttpAttributeRoutes();
        //config.Routes.MapHttpRoute(
        //    name: "DefaultApi",
        //    routeTemplate: "api/{controller}/{id}",
        //    defaults: new { id = RouteParameter.Optional }
        //);
    }
}

执行调用的控制器文件也有合适的CORS头文件:

{
    [EnableCors(origins: "*", headers: "*", methods: "*")]
public class RefurbItemsController : ApiController
{
    // GET: api/RefurbItems
    [Route("api/RefurbItems")]
    public HttpResponseMessage Get()
    {
        var items = RefurbItems.GetAllItems();
        HttpResponseMessage response = Request.CreateResponse(HttpStatusCode.OK, items);
        return response;
    }
    // GET: api/RefurbItems/5
    public string Get(int id)
    {
        return "value";
    }
    // POST: api/RefurbItems
    public void Post([FromBody]string value)
    {
    }
    // PUT: api/RefurbItems/5
    public void Put(int id, [FromBody]string value)
    {
    }
    // DELETE: api/RefurbItems/5
    public void Delete(int id)
    {
    }
}

它在我的开发机器和服务器本身的本地运行良好，但是当我试图将它部署到web并查看页面时，我得到以下错误消息:在Access-Control-Allow-Origin头文件中找不到Origin。XMLHttpRequest: Network Error 0x80070005, Access is denied.

如果有人可以帮助一些想法或任何我开放尝试我是新的asp.net
