I want to extract just the "domain" and "extension" parts from an nginx
server_name for use as variables later in nginx conf.
For example,
server_name <some PERL regex ... ?<domain> ... ?<extension>
...>;
...
location = /test.html {
alias /local/path/to/$domain.$extension.html;
}
No matter what the server_name contains, from
mydomain.tld
to
https://www.mydomain.tld:80/something
and variations in between,the result should be
$domain = mydomain
$extension = tld
I found this post
"Perl Regex to get the root domain of a URL"
http://stackoverflow.com/questions/15627892/perl-regex-to-get-the-root-domain-of-a-url
that suggest this perl regex
^.*://(?:[wW]{3}\.)?([^:/]*).*$
works to extract & return "domain.tld" from any from of input URI.
What's the right form of that regex in nginx's server_name to populate
<domain> and <extension> variables for subsequent use?
