How to correctly compose a regular expression for nginx rewrite?

Question

Nginx

Good afternoon!
I ask for help from the regexp gurus in solving the problem. There is a link like

http://www.site.com/upload/catalog/posob/_/s/_s-1024_cover_image_small.jpeg

For some time now it has changed to

http://www.site.com/upload/catalog/posob/_/s/_s-1024_/cover_image_small.jpeg

It is necessary when trying to go to the first link to send the visitor to the second.
In this case, in place of 1024 there can be any number.
Thank you.

Answer 1

location ~ /upload/catalog/posob/_/s/_s-(?<code>\d+)_cover_image_small.jpeg$ {
     rewrite ^ /upload/catalog/posob/_/s/_s-$code/cover_image_small.jpeg last;
 }


</code>


PS /code не нужен это что то тостер глючит с тегами
