": pcre_compile() failed: missing terminating ]" in rewrite rule

Server NGINX

Hi.

I’m trying to do some rewrite. My url is:
http://domain.tld/stream/file/{username}{crc_username}{hash-file}.{extension}
and I’m want it to rewrite it to different location, where files
physically are.

    location ^~ /stream/file/ {
            rewrite

“([a-f0-9]{8})([a-f0-9]{8})([a-f0-9]{40})(.[^./\]*)$?”
/files/$1.$2/$3$4 last;
alias /home/resources/upload/;
mp4;
}

and while testing configuration I got error:
[emerg]: pcre_compile() failed: missing terminating ] for character
class in “([a-f0-9]{8})([a-f0-9]{8})([a-f0-9]{40})(.[^./]*)$?”

And I don’t see why I missed one ] ? When I add ] to the end I got
error: pcre_compile() failed: missing terminating ).

Any help appreciate :slight_smile:

nginx uses '' as escape character in it’s config syntax, and it
should be doubled if you want to pass it literally.

(and you don’t need '' before ‘.’ in character group; and don’t
need '' before ‘/’; and ‘?’ can’t follow ‘$’)

Regexp printed in error message is a hint.
