Nginx Config Location Regex With Language Code In Url

问题

Trying to achieve constant language code in url's 1st segment with nginx regex location configuration and could not find the correct syntax.

Necessary result:

• example.com stays example.com
• example.com/en stays example.com/en
• example.com/en/ stays example.com/en or example.com/en/ (don't care)
• example.com/en/etc stays example.com/en/etc
  
  
• example.com/etc changes to example.com/en/etc

• example.com/etc/segment changes to example.com/en/etc/segment
  
  
  
  Currently I have found out this code but it still stuck in somewhere. It makes permanent loop and doesn't not use $1 argument.

  location ~ "^/(?![a-z]{2}/)(.+)$" {
      rewrite / /en/$1 permanent;
  }
  
  #Using handler here for removing index.php in uri (example.com/index.php -> example.com);
  location / {
      index index.htm index.html index.php;
      try_files $uri $uri/ @handler;
  }
  
  location @handler {
      rewrite / /index.php?$query_string;
  }
