解决方法
您可以使用操作中的viewmodel或ViewData返回文件的地址,并使用window.location.href,如视图末尾的以下代码所示.
调节器
public ActionResult Index()
{
/* ... */
ViewBag.FileName = "{FileName}";
return View();
}
public ActionResult Download(string id) {
/* ... */
return File("{Path}","{MIME type}","{Desired file name}");
}
<script type="text/javascript">
window.location.href = "/home/download/" + "@Ajax.JavaScriptStringEncode(@ViewBag.FileName)";
</script>
