找到了这个，但我想查询字符串。
RewriteEngine On
RewriteBase /
RewriteCond %{THE_REQUEST} 's/+profile'.php'?u=([^'s&]+) [NC]
RewriteRule ^ /%1? [R=302,L]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)/?$ profile.php?u=$1 [L,QSA]
为两个参数添加新的重定向和重写规则：
RewriteEngine On
RewriteBase /
RewriteCond %{THE_REQUEST} 's/+profile'.php'?u=([^'s&]+)&name=([^'s&]+) [NC]
RewriteRule ^ /%1/%2? [R=302,L]
RewriteCond %{THE_REQUEST} 's/+profile'.php'?u=([^'s&]+)'s [NC]
RewriteRule ^ /%1? [R=302,L]
RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^ - [L]
RewriteRule ^([^/]+)/([^/]+)/?$ profile.php?u=$1&name=$2 [L,QSA]
RewriteRule ^([^/]+)/?$ profile.php?u=$1 [L,QSA]
