lookahead regex in nginx location

Question

I'm trying to match /category/anything, except /category/paid in nginx location.

I have the following regex, but it's not working. Google tells me that I can use lookahead in nginx. Am I doing something wrong?

location ^/category(?!/paid)/ {

}

You either need a slash before it or an escaped slash.

location ~ (category/(?!paid)) { .. }
location ~ (category\/(?!paid)) { .. }

That's exactly what I was looking for! Thanks! one more question..looks like my regex doesn't match /category/paid-test. I've added $ at the end, but it still doesn't match. Do you have any idea? – Moon Sep 04 '13 at 01:47

Maybe something like `category/(?:paid(?=-)|(?!paid))` – hwnd Sep 04 '13 at 02:24

I dont understand what's the difference between `^/category(?!/paid)/` and `(category/(?!paid))` both should be equivalent and work for the example (match /category/anything, except /category/paid). What am I missing there? – Freefri Oct 26 '17 at 11:51
this (category/(?!paid)) not matches paid prefix not a directory only. these are bad: category/paid21398410 category/paid/ – Shimon Doodkin Aug 02 '20 at 07:18
