Regular expression length syntax not working?

Server NGINX
1

Hi

This is my second post. :slight_smile:

I have a regular expression in my location directive to match on a URL.

When I use:

http {
…

    location ~ ^/event/[0-9,A-Z]{16}/info$ {
        proxy_pass http://localhost:7777;
    }
}

}

I don’t get a match.

I have to manually repeat the [0-9,A-Z] sixteen times to get a match.
Escaping the {} doesn’t work either, i.e. /[0-9,A-Z]{16}/info

How can I use the {} syntax correctly?

nginx-V output, below.

nginx.conf used here:

All help appreciated.

Thank you.

Mik

I don’t get a match.

[root@monolith1 nginx]# sbin/nginx -t
nginx: [emerg] unknown directive “16}/info$” in

I suspect that you also don’t get the config file used at all.

This page seems to describe the nginx regular expression syntax

http://nginx.org/en/docs/http/server_names.html#regex_names

HI Francis

The link to the doc was exactly what I was looking for.

The regex works as expected now.

Thanks

Mik
