How to add extension to uri in nginx?

Question

Nginx

It is necessary that nginx requests like:
localhost/zbx/$filename be
remade into
localhost/zbx/$filename.jpg

location /zbx/ {
              rewrite ^[\w|\d|\ |\_|\-]+(?!\.pdf)$  $1.jpg permanent;
              return 301;
        }

Answer 1

location ~ ^/zbx/ {
  try_files $uri $uri.pdf =404;
}

Naturally, root must be registered, otherwise the files will be searched in /etc/nginx.
