我终于解决了这个问题。我的解决方案的结构是这样的，它有一个WebAPI和一个Web应用程序。所以在WebApiConfig.cs文件中我添加了 config.EnableCors（）; 这一行，并且它有效。

public static void Register(HttpConfiguration config)
        {
            // Web API configuration and services

            config.EnableCors();

            // Web API routes
            config.MapHttpAttributeRoutes();

            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );


        }
