尝试在浏览器中打开文件时，显示访问被拒绝错误 [英] When trying to open a file in my browser, it shows access is denied error

问题描述

我试图在浏览器中打开一个文件，它显示访问被拒绝错误



我试过System.Diagnostics.Process.Start（strFilePath& strFileName） ，这适用于本地但不在服务器上并尝试以下代码

I tried to open a file in my browser, it shows access is denied error

I tried System.Diagnostics.Process.Start(strFilePath & strFileName) , this works on local but not on server and tried the following code

strTemp = "<script language='javascript'>function NewWindow()
  {window.open("file://C:\\Users\\Ruban Jayakumar\\Desktop\\New folder\\boot strap icons.txt",'testpage','directories=no,location=no,status=no,toolbar=no,menubar=yes,height=450,width=700,left=10,top=10,Resizable=yes');return false; }</script>"
ClientScript.RegisterClientScriptBlock(Me.GetType, "SecurityPolicy", strTemp)

但是发生了错误，还有其他选择吗？

but error occurs, is there any other option ??

推荐答案

这对你来说实际上是个好消息!!! br />
你在这里看到的是安全保障......

想象一下，任何一个人都可以写一个可以无限制地访问你的C：驱动器的网站......

因此，根据定义，网页无法访问浏览器运行的计算机上的本地驱动器...

...

但我怀疑你打算从你服务网页的服务器的C：驱动器中打开一个文件...如果一个人可以从一个网络服务器上访问驱动器，这应该是一个真正的安全灾难。网页只是因为它最初是从该服务器提供的...

如果你想从你的服务器共享一个文件，你有几个安全选项：

1.创建一个道琼斯为你做的nload按钮

2.使用虚拟目录共享文件

3.创建一个页面直接将文件流式传输到客户端...（使用简单网页流式传输文档 [ ^ ]）

And it is actually good news for you!!!
What you saw here is security in action...
Imagine that anyone, who whish so can write a web site that can access your C: drive without any restriction...
So, by definition web pages have no access to the local drives on the computer on which the browser runs...
...
But I suspect that you meant to open a file from the C: drive of the server from where you served the web page...and it should be a real security disaster if a could access the drives on the web server from within a web page just because it was served from that server originally...
If you want to share a file from your server you have several secure options:
1. Create a download button that does it for you
2. Share the file using Virtual Directory
3. Create a page to stream the files directly to client...(Stream Your Documents Using Simple Web Page[^])
