问题描述

大家好，
我想知道如何跟踪我的下载并隐藏直接链接.
像:http://example.com/direct.zip
到:http://example.com/download?file = direct.zip或类似的文件.

Hi folks,
I want to know how I can track my downloads and hide direct links.
like: http://example.com/direct.zip
to:http://example.com/download?file=direct.zip or some like this.

How can do this?

推荐答案

在url中提供文件名就像给出确切路径一样.您可以使用以下方式实现它.

在页面上提供下载列表-能.使用用户单击所需文件时，您会将其重定向到带有查询字符串中的productid的download.aspx页(download.aspx?pid = 5)

在下载页面上，将此代码在pid为case的switch case块下使用.

这个例子处理的是excel表格，最好的地方是

1.将不会重定向aspx页面，但是将下载文件.
2.用户不会从URL知道文件的路径

代码是:

providing file name in url is like giving the exact path. you can use the following way to achive it.

provide list of download - ables on a page. use user clicks on desirable file you will redirect it to download.aspx page with productid in querystring (download.aspx?pid=5)

at download page use this code under a switch case block with pid as cases.

this example deals with excel sheet and the best points are

1. There will no redirection of aspx page, but file will be downloaded.
2. User will not come to know the path of file from URL

Here''s the code is :

FileInfo file = new FileInfo(PathToExcelFile);
if (file.Exists)
{
   Response.Clear();
   Response.ClearHeaders();
   Response.ClearContent();
   Response.AddHeader("content-disposition", "attachment; filename=" + fileName);
   Response.AddHeader("Content-Type", "application/Excel");
   Response.ContentType = "application/vnd.xls";
   Response.AddHeader("Content-Length", file.Length.ToString());
   Response.WriteFile(file.FullName);
   Response.End();
}
else
{
   Response.Write("This file does not exist.");
}
