ASP.NET MVC 3文件下载：在IE8不工作 [英] ASP.NET MVC 3 File download: Not Working in IE8

问题描述

我有一个简单的供应以在Chrome和Firefox的作​​品本地文件系统的静态zip文件下载，但不是在IE8。

该网站上使用SSL本地主机上运行，​​但我在IE中得到以下错误消息。

  

无法下载下载/从本地主机。

  
  

无法打开此Internet站点。该请求的站点
  不可用或不能被发现。请稍后再试。

 公众的ActionResult下载（长batchID）
{
    VAR batchFilePath =的String.Format（BatchOrderReportsFolder +\\\\分批{0} \\\\分批{0}的.zip，batchID）;
    如果（！System.IO.File.Exists（batchFilePath））{
        返回RedirectToAction（指数，错误）;
    }    返回文件（batchFilePath，应用程序/压缩，Path.GetFileName（batchFilePath））;
}
 

解决方案

下面是最终为我工作。就我而言，有上OnActionExecuted一个全球性的ActionFilter被设置缓存控制为无缓存。

 保护覆盖无效OnActionExecuted（ActionExecutedContext filterContext）
{
    base.OnActionExecuted（filterContext）;
     VAR browserInfo = Request.Browser.Browser;
    如果（filterContext.Result是FileResult）{
        filterContext.HttpContext.Response.CacheControl = browserInfo ==IE？ 私：无缓存;
    }
}
 

I have the Download that simply serves a static zip file from the local file system that works in Chrome and Firefox, but not in IE8.

The website is running on localhost with SSL, but I am getting the following error message in IE.

Unable to download Download/ from localhost.

Unable to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later.

public ActionResult Download(long batchID)
{
    var batchFilePath = string.Format(BatchOrderReportsFolder + "\\Batch-{0}\\Batch-{0}.zip", batchID);
    if (!System.IO.File.Exists(batchFilePath)) {
        return RedirectToAction("Index", "Error");
    }

    return File(batchFilePath, "application/zip", Path.GetFileName(batchFilePath));
}

解决方案

Here's what ultimately worked for me. In my case, there was a global ActionFilter on OnActionExecuted that was setting cache-control to "no-cache".

protected override void OnActionExecuted(ActionExecutedContext filterContext)
{
    base.OnActionExecuted(filterContext);
     var browserInfo = Request.Browser.Browser;
    if (filterContext.Result is FileResult) {
        filterContext.HttpContext.Response.CacheControl = browserInfo == "IE" ? "private" : "no-cache";
    }
}
