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

我正在处理遗留应用程序的替换应用程序。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String路径（通常是存储在Windows共享驱动器上的文件）。然后，遗留应用程序可以通过打开Windows命令shell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.

旧版（Oracle Forms）应用程序正在逐步淘汰基于JSF的J2EE Web应用程序。新应用程序需要能够以某种方式打开或链接到这些传统附件。这有可能吗？我试图使用file：// URL，但使用它们有很多警告。它们只能在IE中的远程主机上工作，firefox / chrome（以及我认为的其他现代浏览器）会阻止本地文件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.

只能在IE上工作才能适应这一特定功能。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遇到包含空格的文件路径，请说

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 Settings\user123\My Documents\testing\someFile.txt

它拒绝打开该链接。浏览器会自动将空格（''）替换为其编码'％20'的URL。

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

我尝试的相关链接如下：

The associated link I am attempting looks like:

<a href="file:///C:\Documents and Settings\user123\My Documents\testing\someFile.txt">link</a>

我有什么简单的东西吗？或者有更简单的方法吗？

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

我不太清楚要标记什么，所以可以根据需要随意重拍。

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后，我得出以下结论：

After some extensive testing I have reached the following conclusions:

• 只有IE会打开远程主机页面上的file：//链接，其他浏览器会直接阻止它们，当用户点击它们时不会发生任何事情。


• IE将只打开file：//指向驻留在网络驱动器上的文件的URL
  
  
  
  • 如果用户单击指向文件的文件：//链接用户的本地驱动器，什么都不会发生，他们不会收到任何错误。
  
  

  希望如此这有助于其他人在寻找文件网址上的信息。

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