php - .htaccess 内部重定向不适用于字符串参数

Question

所以我已经处理这个问题好几个小时了，但无法解决。 stackoverflow 上没有任何内容可以解决我的问题。问题是我的 .htaccess 中有一个重定向规则，如下所示

RewriteRule ^store-category/(.+)/?$ /wordpress/store-category/?cid=$1 [QSA,L]

此重定向在 cid 为数字时有效，但在使用像 "my-key" 这样的字符串时无效。使用 key ，我必须将规则更改为此。

RewriteRule ^store-category/(.+)/?$ /wordpress/store-category/?cid=$1 [R,L]

但是我不想使用它，因为这会明显地重定向我的用户并且 url 会发生变化，这是我不想要的。任何人都可以解释为什么这个东西适用于数字而不适用于字符串参数。任何帮助将不胜感激。

编辑完成.htaccess

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /wordpress/
RewriteRule ^index\.php$ - [L]
RewriteRule ^store-category/(.+)/?$ /wordpress/store-category/?cid=$1 [QSA,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /wordpress/index.php [L]
</IfModule>

# END WordPress

我在本地做了一些尝试，发现如果我设置以下两个规则，它对我有用:

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

甚至在行之前

RewriteRule ^store-category/(.+)/?$ /wordpress/store-category/?cid=$1 [QSA,L]

完整的 .htaccess 文件将是:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /wordpress/

RewriteRule ^index\.php$ - [L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^store-category/(.+)/?$ /wordpress/store-category/?cid=$1 [QSA,L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /wordpress/index.php [L]
</IfModule>

无论如何，对于 (.+)/?$，将从组中捕获最终的尾部斜杠并将继续 cid 参数。如果类别内部没有斜杠，最好使用 ([^/]+)/?$。

更新:了解您的重定向发生了什么，启用日志(参见 http://httpd.apache.org/docs/current/mod/mod_rewrite.html fo)。在我的主机上，我启用了 mod_rewrite.c:trace3 并且在 error_log 中得到了以下日志(只是使用 rewrite 跟踪行)

(在尝试查找默认文档 index.php 时会进行其他一些日志记录)
