in thread Running JavaScript from within Perl

There is no element named "meta.links.self" in the returned JSON, so when you try to set $feedurl to that it is unititialised.

Also, you call $ua->get($url)->result->json twice in the space of 3 lines. DRY.

use strict;
use warnings;
use Mojo::UserAgent;
use Data::Dumper;

my $url = 'https://public-api.wordpress.com/rest/v1/read/feed/34259929
+';

my $ua = Mojo::UserAgent->new;

my $json = $ua->get($url)->res->json;
print Dumper ($json);

my $subscribers = $json->{subscribers_count};
print "\nNumber of subscribers: $subscribers\n";

my $feedurl = $json->{meta}{links}{self};
print "URL is $feedurl\n";

This works for me. My version of Mojo::UserAgent (Mojolicious 5.77) does not have a result method. YMMV.

    I responded in error (figured out my mistake). How do I delete my response?

      You shouldn't, perhaps only <strike> out the things no longer relevant and mark edits with "Update". See How do I change/delete my post?

        Nobody lost a learning opportunity through missing the post I deleted, which posed a question that was already answered elsewhere in the thread.

        Is it possible for me to get am email notice every time someone contributes to a thread I originated? I didn't see an option for that in the Settings.

        Thanks to everyone who responded to this thread. You folks have been extremely helpful to me and I worry about trying your patience. I now have a script that appears to work and do what I wanted (though I'm still testing it).
