链接到 Web 应用程序中的本地内容 [英] Linking to local content in a web application

问题描述

我正在开发旧应用程序的替代应用程序.由于遗留应用程序的某些设计限制，附件"在我们的数据库中存储为字符串路径(通常文件存储在 Windows 共享驱动器上).然后，遗留应用程序可以通过打开 Windows 命令外壳并执行给定路径来打开"附件.

I am working on a replacement application to a legacy application. Due to certain design limitations of the legacy application, 'attachments' are stored as a String path in our database (generally files stored on a windows shared drive). The legacy application can then 'open' the attachments by opening a windows command shell and executing the given path.

旧的 (Oracle Forms) 应用程序正在被基于 JSF 的 J2EE Web 应用程序淘汰.新应用程序需要能够以某种方式打开"或链接到这些旧附件.这甚至可能吗?我曾尝试使用 file://URL，但使用它们有很多注意事项.它们仅适用于 IE 中的远程主机，firefox/chrome(以及我假设的其他现代浏览器)阻止本地文件 URL.

The legacy (Oracle Forms) application is being phased out by a JSF based J2EE web application. The new application needs to be able to 'open' or link to these legacy attachments somehow. Is this even possible? I have attempted to use file:// URLs, but there are lot of caveats with using them. They only work on remote hosts in IE, firefox/chrome (and other modern browser I assume) prevent local file URLs.

仅在 IE 上工作是可以使用此特定功能的东西.我进一步遇到了带空格的文件路径问题.出于某种原因，如果 IE 遇到一个包含空格的文件路径，比如

Working only on IE is something that can be lived with for this particular feature. I further ran into an issue with file paths with spaces. For some reason if IE encounters a filepath with spaces in it, say

C:Documents and Settingsuser123My Documents	estingsomeFile.txt

它拒绝打开那个链接.浏览器会自动用其 URL 编码的%20"替换空格 ("").

it refuses to open that link. The browser automatically replaces the spaces (' ') with its URL Encoded '%20'.

我正在尝试的关联链接如下所示:

The associated link I am attempting looks like:

<a href="file:///C:Documents and Settingsuser123My Documents	estingsomeFile.txt">link</a>

我错过了一些简单的东西吗?或者有没有更简单的方法?

Is there something simple to this I am missing? Or is there any easier way of doing this?

我不太确定要标记什么，因此请随时根据需要重新标记.

I wasn't quite sure what to tag this as so feel free to retag as necessary.

推荐答案

经过一些广泛的测试，我得出了以下结论:

After some extensive testing I have reached the following conclusions:

• 只有 IE 会打开来自远程主机的页面上的 file://链接，其他浏览器会完全阻止它们，当用户点击它们时不会发生任何事情.
• IE 只会打开 file://URL 指向驻留在网络驱动器上的文件
  • 如果用户单击指向用户本地驱动器上文件的 file://链接，则不会发生任何事情，也不会出现错误.

  希望这能帮助其他正在寻找文件 url 信息的人.

  Hopefully this helps someone else out who's looking for information on file urls.
