How to exclude words in this regular expression?

Question

Nginx

There is this code in the nginx config:

if (!-f $request_filename ) { rewrite ^([^.\?]*[^/])$ "$1/" permanent; }

It adds a slash to all links. But I need not to all, but to exclude certain words. Those. if they are in the link, do not add a slash (for example: api, admin, storage). How can I do that?

Answer 1

rewrite ^(/(?!api|admin|storage)[^.\?]*[^/])$ "$1/" permanent;
