我在 htaccess 中做这个来重写 url
Options +FollowSymLinks
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([a-zA-Z0-9_-]+)$ index.php?username=$1 [QSA]
RewriteRule ^([a-zA-Z0-9_-]+)/$ index.php?username=$1 [QSA]
但现在我努力把它改成这样
RewriteRule ^([a-zA-Z]{2}).([a-zA-Z0-9_-]+)$ index.php?prefix=$1&username=$2 [QSA]
并且它的工作正常..但是在这样的规则中将 {2} 更改为 {2,4}
RewriteRule ^([a-zA-Z]{2,4}).([a-zA-Z0-9_-]+)$ index.php?prefix=$1&username=$2 [QSA]
它使网站非常慢..
最终链接应该是 sitename.com/prefix.name == index.php?prefix=$1&username=$2
谁能帮我改写规则？！
