我可以在 Firefox 中打开本地文件，其链接如下： file:///home/user
可能的重复：
Firefox 链接到本地或网络页面不起作用
大家好，
我想知道如何为连接到我的网站（JAVA - JSP 页面）的用户提供通过 Web 浏览器显示其 PC 中文件内容的功能。
更准确地说，我想要一个按钮，当用户单击时，它会打开一个新选项卡或新窗口（浏览器的），其路径如下：file:///home/user...
我确实尝试过我的流程代码片段：
<script type="text/javascript">
[...]
window.open("file:///home/user...");
[...]
</script>
当我使用 Firefox 手动打开 html 文件时，这工作正常，但是当我尝试将其加载到应用程序服务器（Java EE）中时，它根本不起作用。我在我的错误控制台（firefox）中收到这样的消息：
Security Error: Content at http://localhost:8080/MyProject/test.jsp may not load
or link to file:///home/user.
这似乎是与 Firefox 安全策略相关的问题，但我仍然没有发现任何问题来解决我的问题...
您有什么想法吗这？

Firefox Links to local or network pages do not work
Hi all,
I would like to know how can i offer users that connected in my web site (in JAVA - JSP pages) to show the contents of files in THEIR PC over Web browser.
More precisely, i want to have a button, on what when user click, it open a new TAB or new window (of the browser) with path like : file:///home/user...
I did try with my flowing snippet of codes:
<script type="text/javascript">
[...]
window.open("file:///home/user...");
[...]
</script>
this works fine when i open my html file manually with Firefox, but when i try to load it in a application server (Java EE), it doesn't work at all. I get this kind of message in my error console (of firefox):
Security Error: Content at http://localhost:8080/MyProject/test.jsp may not load
or link to file:///home/user.
It seems to be a problem related to the security policies of Firefox, still i didn't found any issues to resolve my problem ...
Do you have any ideas about this?

由于安全原因这是不可能的。
It's impossible because of security reasons.
不允许远程页面链接到
file://页面，因为它允许对浏览器进行攻击，在某些情况下还对操作系统进行攻击。例如，Linux 上的
Remote pages are not allowed to link to
file://pages because it allows attacks on the browser, and in some cases on the OS. For example,<img src="file:///dev/tty">on Linux will hang the browser for most users (the few running it from a terminal will be able to recover by foregrounding it, but that's it).无法通过 Web 应用程序读取本地文件，但是，您可以要求用户先上传文件，然后打开它。
It's not possible to read a local file through your web application, however, you can ask the user to upload the file first and then open it.
