Asp .Net MVC中常用过滤属性类

 1         /// <summary>
 2     /// 
 3     /// </summary>
 4     public class AjaxOnlyAttribute : ActionFilterAttribute
 5     {
 6         /// <summary>
 7         /// Called by the ASP.NET MVC framework before the action method executes.
 8         /// </summary>
 9         /// <param name="filterContext">The filter context.</param>
10         public override void OnActionExecuting(ActionExecutingContext filterContext)
11         {
12             if (!filterContext.HttpContext.Request.IsAjaxRequest())
13             {
14                 filterContext.Result = new ContentResult() { Content = "只支持Ajax方法调用。", ContentEncoding = Encoding.UTF8, ContentType = "text/html" };
15                 //new HttpNotFoundResult();
16             }
17             base.OnActionExecuting(filterContext);
18         }

只允许通过Ajax调用
