.htaccess重定向并保留文件名，不带文件扩展名

I'm redirecting but now I want to preserve the file name to resemble a directory.

I would add a query string with the name of the file to add it to the redirect URL but that doesn't make much sense.

e.g

RewriteCond %{THE_REQUEST} \ /+profile\.php\?user=([^&]+)&uid=([^&\ ]+)
RewriteRule ^ /%1/%2? [L,R=301]

Internal

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/([^/]+)$ profile.php?user=$1&uid=$2 [L,QSA]

this redirects to www.site.com/username/uid

I want this to be www.site.com/profile/username/uid

I would add a third query string like www.site.com/profile.php?user=username&uid=45&profile but it doesn't make much sense.

You might slightly modify the rewrite rule.

  RewriteCond %{THE_REQUEST} \ /+profile\.php\?user=([^&]+)&uid=([^&\ ]+) 
  RewriteRule ^ /profile/%1/%2? [L,R=301]

And internally.

  RewriteRule ^profile/([^/]+)/([^/]+)$ profile.php?user=$1&uid=$2 [L,QSA]
