我正在构建一个应用程序,它将关闭服务器,ping该服务器,并在服务器关闭时通知用户。如果它没有成功关闭,它允许用户“再试一次”。我可以让应用程序第一次正确处理逻辑,但是当我实现“再试一次”功能时,它不会重新处理关机操作。我认为它必须与缓存有关,但我不知道它知道从哪里开始寻找。有什么想法吗?
这是我的代码:
控制器
//URL: Build/Progress
public ActionResult Progress()
{
return View();
}
////URL: Build/MoveDevice
public ActionResult ShutdownStatus()
{
ImageInfo ImageInfo = new ImageInfo();
FarmInfo FarmInfo = new FarmInfo();
ProgressModel ProgressModel = new ProgressModel();
if ((Session["ShutdownStatus"] as string) == "Success")
{
ProgressModel.ShutdownStatus = 1;
return View(ProgressModel);
}
else
{
ImageInfo = svcImage.GetImageInfoByImageId(Session["ImageName"].ToString());
string Farm = ImageInfo.FarmId.ToString();
FarmInfo = svcFarm.GetFarmByFarmId(Farm);
svcImageSvc.ShutdownDevice(Session["Username"].ToString(), Session["Password"].ToString(), Session["Domain"].ToString(),
FarmInfo.farmName, ImageInfo.Device, ImageInfo.ImageHistory.Status, ImageInfo.PVSHost, ImageInfo.PVSAccount);
ProgressModel.ShutdownStatus = svcImageSvc.PingDevice(ImageInfo.Device);
return View(ProgressModel);
}
}

我相信缓存实际上是由jQuery完成的。将$ .get更改为$ .post,看看它是否有效。如果是,您仍然可以使用$ .get,但您需要设置选项:
cache: false

尝试添加:
[OutputCache( Location = OutputCacheLocation.None )]
到你的控制器(或你不希望被缓存的每个动作)。
您要做的另一件事是将您的javascript包装在document.ready()处理程序中。这并不是绝对必要的,因为你的脚本在它引用的元素之后发生,但它仍然是一个很好的实践 - 你也可以将它移动到结束体标记之上,但这更像是一种优化。
<script type="text/javascript">
$(function() { // execute on document ready
$.get('<%= Url.Action("ShutdownStatus", "Build", null) %>',
function (data) {
$('#panel1').replaceWith(data);
});
});
</script>
