Question

我试图解决下列问题:

I have a download button that when clicked, redirects to a file for download. Example:

答复:Redirect(http://www.example.com/data/file1.zip);

当这个纽子被点击时,你就拿到了一张菜单,因为你可以要求科索沃下载。

但是,如果我有:

答复:Redirect(http://www.example.com/data/textfile.txt);

I get a piece of text instead. I don t want this behavior.

How can I make a menu pop all cases when you click to download the file.

我尝试如下:

Response.ContentType = "application/octet-stream";

Response.Redirect("http://www.example.com/data/" + filename);

但是,如果我点击它的话,我仍然只是拿着灯塔的内容。是否有办法检查是否实际采用了这种奇米类型?

Answer 1

您需要确定反应类型,

流层应迫使用户开放或拯救档案

类似情况

public class Download : IHttpHandler {
    public void ProcessRequest (HttpContext context) {
        string filename = context.Request.QueryString["file"];
        string file = context.Server.MapPath(filename);
        context.Response.ContentType = "application/octet-stream";
        context.Response.AddHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(filename));
        try
        {
            context.Response.TransmitFile(file);
        }
        catch (Exception ex)
        {
            SendFailedDownload(filename, context);
        }
        finally
        {
        }
    }
}

Answer 2

不要采取上述行动,就只是使用链条,把手ef锁定在案卷中。这不需要调整方向或调整情况。

<a href="<link to file>" title="">Download me </a>

这将促使你拯救或开放......

t 案卷的工作的确为其他文件工作。
