用户应该无法下载文件 [英] User should not able to download file

问题描述

亲爱的朋友，

我在网络服务器上有多个扩展名不同的文件(例如.doc，.xls，.pdf，.mp3，.zip ....).

现在，我希望如果用户访问链接中的文件名，那么除了已登录的用户外，不应下载该文件.

例如，
文件名为"myfiles.zip"
链接是http://www.mysite.com/myfiles.zip

因此，如果最终用户直接访问http://www.mysite.com/myfiles.zip，则不应下载.

但是，如果用户已登录该应用程序，则应下载该文件.

如何在ASP.Net 2.0和SQL 2005中使用?

请帮助我解决以上问题.

提前谢谢.

:-)

Hi Dear Friends,

I have multiple files on web-server with different extension (e.g., .doc, .xls, .pdf, .mp3, .zip....).

Now, I want that if user access file name in link then that file should not be download, except the logged in user.

Example,
file name is "myfiles.zip"
link is http://www.mysite.com/myfiles.zip

So, if end user direct access http://www.mysite.com/myfiles.zip, then it should not download.

But if user is logged in the application then that file should download.

How to use in ASP.Net 2.0 and SQL 2005 ?

Please HELP me to resolve above issue.

Thanks in advance.

:-)

Rohit

推荐答案

hi,
Put your files (those you dont want to directly accesssible) under downloadfiles folder.
on web config put the codes given below,
<location path="downloadfiles">
    <system.web>
      <authorization>
        <deny users="?"/>
      </authorization>
    </system.web>
  </location>
This section should be placed out side <system.web> section
Target file will download if user login.
Hope this will  help
