Question

我的按钮点击事件需要很长时间才能处理（> 60分钟）。我试图使用setInterval事件来保持我的会话活着。

function OnButtonClick(s, e, startUrl, progressUrl) {
    StartActionOnServer(startUrl);
    setInterval(keepalive, 2000);
}

function keepalive()
    {

        $.ajax({
            type: 'POST',
            url: '/ImportData/alive',
            dataType: "text",
            contentType: "text",
            success: function (msg) {
                console.log(msg);
            },
            error: function (xhr) {
                alert(xhr)
            },
        });
     }

    [HttpPost]
    public ActionResult alive()
    {
        var result = "I am pinging the server";
        return Content(result);
    }

问题在于，我希望setInterval(keepalive, 2000);在StartActionOnServer(startUrl);运行约1小时时运行。这是为了让我的视图更新。现在没有发生这种情况。我的Console.log看起来像：

我希望它看起来。

I am pinging the server.
I am pinging the server.
I am pinging the server.
I am done

知道如何实现这一目标。感谢帮助。

更新：添加了其他使用的方法：

function StartActionOnServer(startUrl) {
        positionDate = ReportingPositionDate.GetDate().toDateString();
        myProgressBar.Show;
        $.ajax({
            type: 'POST',
            url: startUrl,
            data: JSON.stringify({ positionDate: positionDate }),
            dataType: "text",
            contentType: "application/json; charset=utf-8",
            beforeSend: function () { lpImport.Show(); },
            success: function (msg) {
                console.log(msg);
                ImportDataGridView.PerformCallback();
                ImportSuccessMessage.SetVisible(true);
                ImportSuccessMessage.SetText(msg);
                lpImport.Hide();
            },
            error: function (xhr) {
                alert(xhr);
            }
        });
    }

按钮点击事件：

settings.ClientSideEvents.Click = string.Format("function(s, e) {{ OnButtonClick(s, e, '{0}', '{1}'); }}", Url.Action("Start", "ImportData", null), Url.Action("alive", "ImportData", null));

Controller Star动作如下所示：

    [HttpPost]
    public ActionResult Start()
    {
        //System.Threading.Thread.Sleep(6000);
        //Thread.Sleep(3600000);
        Thread.Sleep(10000);
        //var result = new { StartResult = "DataFileUpload failed" };
        var ReturnVal = "I am done";
        progress = 0;
        return Content(ReturnVal);
        //return Json(result);
    }

asp.net mvc使用setInterval使Session保持活动状态
