解决方法1：通过为URL地址添加后缀的方式解决问题

 <!DOCTYPE html>
 <html>
     <head>        
            <script type="text/javascript">
                $(function () {
                    window.setInterval(function () {
                        $.ajax({
                            url:'@Url.Action("GetCurrentTime")?'+ new Date().toTimeString() ,
                            success: function (result) {
                               $("ul").append("<li>" + result + "</li>");
                           }
                       });
                   }, 5000);
               });
           </script>
       </head>
  </html>

解决方法2：通过jQuery的Ajax设置解决问题

<!DOCTYPE html>
    <html>
        <head>        
            <script type="text/javascript">
                $(function () {
                    $.ajaxSetup({ cache: false }); 
                    window.setInterval(function () {
                        $.ajax({
                            url:'@Url.Action("GetCurrentTime")',
                           success: function (result) {
                               $("ul").append("<li>" + result + "</li>");
                           }
                       });
                   }, 5000);
               });
           </script>
       </head>
   </html>

解决方法3：适用MVC 通过定制响应解决问题

 public class HomeController : Controller
    {
        public ActionResult Index()
        {
            return View();
        }
     
        [NoCache] 
        public string GetCurrentTime()
       {
           return DateTime.Now.ToLongTimeString();
       }
   }
   public class NoCacheAttribute : FilterAttribute, IActionFilter
   {
       public void OnActionExecuted(ActionExecutedContext filterContext)
       {
           filterContext.HttpContext.Response.Cache.SetCacheability(HttpCacheability.NoCache);
       }
    
       public void OnActionExecuting(ActionExecutingContext filterContext)
       {}
   }
