How can I add nginx rewrite url+last_part with different_url+last_part?

Question

I need to rewrite an nginx rewrite rule, but cant figure out how to do it.

This is my example URL:

cdn.example.com/public/storage/upload/images/1/2/3/4.jpg
cdn.example.com/public/storage/upload/images/1/2/3.jpg

I want to convert it to

cdn.example.com/storage/app/public/upload/images/1/2/3/4.jpg
cdn.example.com/storage/app/public/upload/images/1/2/3.jpg

I am not sure how can I just add storage/app/ in front of the original URL and remove the storage after public from the original URL?

Answer 1

The regex would be:

/public/storage/ /storage/app/public/

Assuming /public/storage/ does not appear anywhere else. Otherwise, include the domain name as well. If 'storage' is a pattern, then

/public/([a-z]+)/ /$1/app/public/
