Question

我有我的行动。多人在这个应用程序上工作，并且有可能同时点击按钮。偶尔我得到以下异常，我该如何解决这个问题？

异常

动作：

[HttpPost]
        [NoCaching]
        public ActionResult CorrectAsIsControl()


[HttpPost]
        [NoCaching]
        public ActionResult UnreadableControl()

NoCaching过滤器

public partial class NoCaching : ActionFilterAttribute
    {
        #region OVERRIDES


        public override void OnResultExecuting(ResultExecutingContext filterContext)
        {
            filterContext.HttpContext.Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1));
            filterContext.HttpContext.Response.Cache.SetValidUntilExpires(false);
            filterContext.HttpContext.Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
            filterContext.HttpContext.Response.Cache.SetCacheability(HttpCacheability.NoCache);
            filterContext.HttpContext.Response.Cache.SetNoStore();

            base.OnResultExecuting(filterContext);
        }


        #endregion
    }

Ajax Post

_performStaticActions: function ($click) {
        var id = $click.attr("rel");
        var link = $click.attr("href");
        if (id == "")
            jMessageError("Unable to find Id, operation aborted!", $click, false, true);
        else if (link == "")
            jMessageError("Unable to find action link, operation aborted!", $click, false, true);
        else {
            jMessage("Processing request...", $click, true, false);

            //link = link + "?badEmailId=" + id;
            $.ajax({
                cache: false,
                url: link,
                type: Ajax.MethodType.POST,
                data: { badEmailId: id},
                error: function (xhr, ajaxOptions, thrownError) {
                    jMessageError(xhr.responseText, $click, false, true);
                },
                success: function (result) {
                    if (result.IsError) {
                        jMessageError(result.Message, $click, false, true);
                    } else {
                        jMessageOK(result.Message + "<br><br>Picking new item...", $click, false, false);
                        setTimeout('PaperSurveyBadEmailCleanUp._pickNewItem()', 3000);
                    }
                }
            });
        }
    }

菲尔·哈克（Phil Haack）发表了一篇很好的文章，他描述了使用“路线调试器”工具，这个工具在像你这样的场景中很有用{链接http://haacked.com/archive/2012/07/25/finding-bad-controllers.aspx

我已经在ajax post操作上取消了NoCaching属性，它似乎有效。我从昨天起没有收到任何错误。现在我需要重新考虑一下NoCaching属性。

未找到控制器/操作
