如何使用mod_rewrite来检查多个文件夹的静态文件 [英] How to use mod_Rewrite to check multiple folders for a static file

问题描述

什么是用于检查一个给定文件的多个文件夹位置mod_rewrite规则。举例来说，如果我有一个文件夹结构：

What are the mod_Rewrite rules for checking multiple folder locations for a given file. For instance, if I have a folder structure of:

public/
    css/
    library1/
        css/
    library2/
        css/

和我想请求 /css/somefile.css 来先检查公共/ CSS / 目录，然后级联公共/ LIBRARY1 / CSS / 然后公共/ library2 / CSS / ，返回404，如果一项资产不能在任何目录中找到。

and I want requests to /css/somefile.css to first check the public/css/ directory, then cascade to public/library1/css/ then public/library2/css/, returning a 404 if an asset cannot be found in any of the directories.

我的线沿线的思考

RewriteCond %{SCRIPT_FILENAME} !-f
RewriteCond library1%{REQUEST_URI} -f
RewriteRule ^(.*)$ library1$1 [L]

RewriteCond %{SCRIPT_FILENAME} !-f
RewriteCond library2%{REQUEST_URI} -f
RewriteRule ^(.*)$ library2$1 [L]

但是，这似乎并没有工作 - 我不知道如何检查文件的存在一个动态生成的路径上。

But this doesn't seem to work - I'm not sure how to check for file existence on a dynamically generated path.

推荐答案

请尝试以下规则：

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{DOCUMENT_ROOT}/library1%{REQUEST_URI} -f
RewriteRule ^css/.+ library1%{REQUEST_URI} [L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{DOCUMENT_ROOT}/library2%{REQUEST_URI} -f
RewriteRule ^css/.+ library2%{REQUEST_URI} [L]
