MVC 5从控制器自动刷新 [英] MVC 5 Auto Refresh From Controller

问题描述

我正在尝试从本地网络服务器加载excel文件，然后每隔5分钟左右刷新一次页面，以防万一该文件已被替换...

I am trying to load a excel file, from a local webserver, then refresh the page every 5min or so, just incase that file has been replaced...

它用于显示时间表，有人会对其进行更新，并且在整个工厂中，页面将显示在监视器上，并且输出将更改...

It is for displaying a schedule, someone will update it and throughout the plant, the page will be displayed on a monitor and the output will change...

我认为这将是非常简单的，我只是将刷新添加到.html文件的标头中并完成操作，但是我认为这仅在使用常规return View()时才有效. ...由于我使用的是重定向，因此不确定是否可以将其添加到标题中...有什么想法吗?

I thought this was going to be super simple, and I would just add a refresh to the header of the .html file and be done, but I think that would only work if I just use the regular return View();... Since I am using Redirect, I am unsure if it is able to add this to the header or not... Any ideas?

这是我添加到控制器中的代码:

Here is the code that I added to my controller:

this.HttpContext.Response.AddHeader("refresh", "5; url=" + Url.Action("time"));
        return Redirect("http://dexweb/scheduler/hunting template.htm");

推荐答案

您似乎正在重定向到某些HTML页面:

It appears that you are redirecting to some HTML page:

http://dexweb/scheduler/hunting_template.htm

在此html内，您可以放置​​ <meta> 标记，以强制其从服务器定期运行:

Inside this html you could put a <meta> tag to force it to refresh from the server at regular intervals:

<meta http-equiv="refresh" content="5">

显然，如今，有更高级的方法可以实现从服务器到客户端的实时推送通知，例如HTML5 WebSockets.

Obviously nowadays there are more advanced ways to achieve real time push notifications from the server to the client such as HTML5 WebSockets.
