Redirect ?lang=en string to subfolder /en

问题

I'd like to do a lot of redirects like this pattern:

domain.com/xxx/?lang=en to domain.com/en/xxx/

For example:

domain.com/about/?lang=en to domain.com/en/about/

This redirects all links */?lang=en to just one target.

RewriteCond %{QUERY_STRING} ^lang=en
RewriteRule ^ en/about/? [R=301,L]

回答1:

You can use these rules in your root .htaccess:

RewriteEngine On

RewriteCond %{THE_REQUEST} \s/+([^/]+)/\?lang=([^\s&]+) [NC]
RewriteRule ^ /%2/%1? [R=302,L]

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([a-z]{2})/([^/]+)/?$ $2/?lan=$1 [L,QSA]

Change 302 to 301 once you make sure code is working fine.
