Codeigniter url使用.htaccess重写为子域名url

Question

目前我的网址是：http://www.domain.co.uk/index.php/city/details/city-name

我想将其更改为：

http://www.city-name.domain.co.uk/index.php/city/details/city-name

或：

http://www.city-name.domain.co.uk/city/details/city-name

Answer 1

将.htaccess文件放入http：//www.domain.co.uk/ document root

致http：//www.city-name.domain.co.uk/index.php/city/details/city-name

RewriteRule ^(.*)/([^/]+)$ http://www.$2.domain.co.uk/$1/$2 [R=301,L]

致http：//www.city-name.domain.co.uk/index.php/city/details/city-name

RewriteRule ^index.php/(.*)/([^/]+)$ http://www.$2.domain.co.uk/$1/$2 [R=301,L] 

如果服务器相同，请在此行上方设置RewriteRule以防止重定向循环

RewriteCond %{HTTP_HOST} !^www\.(.*).domain\.co\.uk [NC]  

文件内容示例

<ifModule mod_rewrite.c>
   RewriteEngine on
   RewriteCond %{HTTP_HOST} !^www\.(.*).domain\.co\.uk [NC]  
   RewriteRule ^index.php/(.*)/([^/]+)$ http://www.$2.domain.co.uk/$1/$2 [R=301,L]  
</IfModule>

排除domain.co.uk（whitout www）

<ifModule mod_rewrite.c>
   RewriteEngine on
   RewriteCond %{HTTP_HOST} !^www\.(.*).domain\.co\.uk [NC]
   RewriteCond %{HTTP_HOST} !^domain\.co\.uk [NC]  
   RewriteRule ^index.php/(.*)/([^/]+)$ http://www.$2.domain.co.uk/$1/$2 [R=301,L]     
</IfModule>
