httpd.conf 中的 apache mod_rewrite 规则，用于修改某些路径，但不修改其他路径

Question

我在为 Fedora 10 上的 Apache/2.2.14 创建适当的重写规则时遇到了很大的挑战。我正在处理使用 .htaccess 文件的CodeIgniter-Doctrine tutorial。 （搜索 Removing “index.php” from CodeIgniter urls 大约降低了 10%。）但由于不建议将其用于生产服务器，我正在尝试对其进行调整以使其在 /etc/httpd/ 中工作conf/httpd.conf。

<VirtualHost *:80>
    ServerName ci_doctrine
    DocumentRoot /var/www/html/ci_doctrine
    ErrorLog /var/log/httpd/cid-error_log
    CustomLog /var/log/httpd/cid-access_log common
        <IfModule mod_rewrite.c>
                RewriteEngine on
                RewriteLog /var/log/httpd/cid_rewrite
                RewriteLogLevel 9

#               RewriteCond ^/css/style.css$  (these have bad syntax, but that's beside the point)
#               RewriteRule ^/css/style.css$ /css/style.css [L]

                RewriteCond %{REQUEST_FILENAME} !-f
                RewriteCond %{REQUEST_FILENAME} !-d
                RewriteRule ^(.*)$ /index.php/$1 [L]
        </IfModule>
        <IfModule !mod_rewrite.c>
                ErrorDocument 404 /ci_doctrine/index.php
        </IfModule>
</VirtualHost>

似乎教程 .htaccess 规则正确测试现有文件，然后在这种情况下不更改 URL，但重写日志显示条件为真（即文件不存在），即使它存在.

在我开始弄乱重写规则之前，文件 .../css/style.css 工作正常，所以它应该在正确的位置。但是现在路径总是被重写弄得一团糟，尽管 index.php 下面的虚拟组件被正确翻译了。我做错了什么？

Answer 1

为了让它工作，我必须像这样更改 ReWriteCond 语句：

RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-f
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-d

REQUEST_FILENAME 的文档说“与请求匹配的文件或脚本的完整本地文件系统路径”，但对我来说，它总是缺少路径的 DocumentRoot 部分，这意味着“文件存在”测试将始终是假的。

也许这是一个 apache 错误，或者只是一个文档错误。我不知道那部分。 http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html#rewritecond

Answer 2

您已注释掉这些规则：

#               RewriteCond ^/css/style.css$  (these have bad syntax, but that's beside the point)
#               RewriteRule ^/css/style.css$ /css/style.css [L]

这些规则中的后者检测到对样式表的请求，将其重写到相同的地址（即什么都不做），然后声明“我是最后一个规则”——这意味着当匹配时，将不再运行任何规则，这阻止它匹配后来找到的规则。

如果你去掉这一行开头的 #，你的 style.css 文件将再次工作，尽管这不是执行地址转换的好方法，因为你必须为你的每个文件添加一个类似的规则不想重写。

Answer 3

仅取消注释 style.css 的 RewriteRule，因为您的 RewriteCond 是错误的（它应该是 RewriteCond %{REQUEST_URI} ^/css/style.css$）并且无论如何都是多余的。
