使用 .htaccess 将子目录重写为 root 但保留对其他子目录的访问权限

Question

我正在尝试从我的 URL 结构中重写一个子目录，但该目录结构中的其他 URL 也可以工作。我有这种情况：

// This should load the content of mysite.com/foo/15 but not redirect
mysite.com/foo/ 

// Subdirectories within /15 should also work
mysite.com/foo/bar // the actual location of this is mysite.com/foo/15/bar

// Other URLs within this directory structure should also work, such as
mysite.com/foo/12
mysite.com/foo/13
mysite.com/foo/14

// Lastly, we have redirects from 2012 -> 12, 2013 -> 13 such that
mysite.com/foo/2012 becomes mysite.com/foo/12
mysite.com/foo/2013 becomes mysite.com/foo/13
... and so on

这就是我所在的位置。我无法获得正确的 htaccess 规则组合来实现我想要的。

RewriteEngine On
RewriteBase /foo/

// This makes mysite.com/foo/ load the content of mysite.com/foo/15 without redirecting, but makes mysite.com/foo/14 404
RewriteRule ^((?!15/).*)$ 15/$1 [NC,L]

// This works pretty well, except the rules below don't redirect
RewriteRule ^$ 15/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ 15/$1

// Rewrite old years to the two digit form
RewriteRule ^2010/(.*)$ 10/$1 [R=301]
RewriteRule ^2011/(.*)$ 11/$1 [R=301]
RewriteRule ^2012/(.*)$ 12/$1 [R=301]
RewriteRule ^2013/(.*)$ 13/$1 [R=301]
RewriteRule ^2014/(.*)$ 14/$1 [R=301]
RewriteRule ^2015/(.*)$ 15/$1 [R=301]

我错过了什么？什么样的规则组合可以帮助我实现我想要的？

Answer 1

您的重定向规则可以使用正则表达式匹配组合成单个规则：

RewriteEngine On
RewriteBase /foo/

// Rewrite old years to the two digit form
RewriteRule ^20(1[0-5])/(.*)$ $1/$2 [R=301,L]

RewriteRule ^$ 15/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^((?!15/).*)$ 15/$1 [L]

Answer 2

尝试在所有规则中包含 L 标志，然后将所有重定向放在 htaccess 文件的顶部：

RewriteEngine On
RewriteBase /foo/

// Rewrite old years to the two digit form
RewriteRule ^2010/(.*)$ 10/$1 [R=301,L]
RewriteRule ^2011/(.*)$ 11/$1 [R=301,L]
RewriteRule ^2012/(.*)$ 12/$1 [R=301,L]
RewriteRule ^2013/(.*)$ 13/$1 [R=301,L]
RewriteRule ^2014/(.*)$ 14/$1 [R=301,L]
RewriteRule ^2015/(.*)$ 15/$1 [R=301,L]

// This makes mysite.com/foo/ load the content of mysite.com/foo/15 without redirecting, but makes mysite.com/foo/14 404
RewriteRule ^((?!15/).*)$ 15/$1 [NC,L]

// This works pretty well, except the rules below don't redirect
RewriteRule ^$ 15/ [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ 15/$1 [L]
