htaccess重写规则以无限循环结束(htaccess rewrite rule ends in an infinite loop)

htaccess重写规则以无限循环结束(htaccess rewrite rule ends in an infinite loop)

我想永久重定向

www.example.com/event/title-goes-here to www.example.com/event/jazz/title-goes-here

在我的htaccess文件中使用正则表达式。

我目前有：

RewriteEngine on RewriteRule ^event/(.*)$ http://www.example.com/event/jazz/$1 [R=301,L]

但这导致无限循环（它转到example.com/event/jazz/jazz/jazz/jazz等），因为/ event / part是相同的。

如何使用重写规则进行重写，并考虑到人们可以访问example.com/event/title-goes-here和example.com/event/title-goes-here/ （因此使用尾部斜杠）同时仍然正确地进行重定向。

编辑/ UPDATE

根据anubhava的回答，我的完整.htaccess文件现在看起来像这样（忘了提到还有一个重写index.php）：

RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule .* index.php/$0 [PT,L] RewriteRule ^event/([^/]+)/?$ /event/jazz/$1 [R=301,L,NC,NE]

还忘了提到我正在使用CodeIgniter而在我的routing.php中有下面列出的路由选项（不知道这是否重要）。 认为这纯粹是一个.htaccess的事情，但是当我想到路由文件时，我想这可能会因重写而混乱？

$route['event/jazz/(:any)'] = 'event/view/$1'; $route['(:any)'] = 'pages/view/$1';

I would like to permanently redirect

www.example.com/event/title-goes-here to www.example.com/event/jazz/title-goes-here

with a regex in my htaccess file.

I currently have:

RewriteEngine on RewriteRule ^event/(.*)$ http://www.example.com/event/jazz/$1 [R=301,L]

But this results in an infinite loop (it goes to example.com/event/jazz/jazz/jazz/jazz etc) because the /event/ part is the same.

How can I use the rewrite rule to make this rewrite, and also in a way that it takes into account that people can go to example.com/event/title-goes-here AND example.com/event/title-goes-here/ (so with a trailing slash) while still correctly making the redirect.

EDIT/UPDATE

Based on anubhava's answer my complete .htaccess file now looks like this (forgot to mention there's also a rewrite on index.php):

RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule .* index.php/$0 [PT,L] RewriteRule ^event/([^/]+)/?$ /event/jazz/$1 [R=301,L,NC,NE]

Also forgot to mention I'm using CodeIgniter and in my routing.php there are routing options listed below (don't know if this matters). Thought this was purely a .htaccess thing but when I thought about the routing file I figured that maybe this messes with the rewriting?

$route['event/jazz/(:any)'] = 'event/view/$1'; $route['(:any)'] = 'pages/view/$1';

最满意答案

是的，它会循环，因为源和目标URI都匹配您的正则表达式模式。

使用此规则来修复它：

RewriteEngine on RewriteRule ^event/([^/]+)/?$ /event/jazz/$1 [R=301,L,NC,NE] RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule .* index.php/$0 [PT,L]

Yes it will loop because source and target URIs both match your regex pattern.

Use this rule to fix it:

RewriteEngine on RewriteRule ^event/([^/]+)/?$ /event/jazz/$1 [R=301,L,NC,NE] RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule .* index.php/$0 [PT,L]
