Just FYI, I've noticed that the first test of
LWP::Protocol::https fails because sometimes, when it tries to connect to the Apache Software Foundation, it connects ok; sometimes, it can't make a connection. For example, I installed it on 5.8.8 with no problems. A couple of hours later, I tried it on 5.16.0, but it couldn't connect. It seems the site is up and down frequently.
The modules are installed, so they should just work.
I think that LWP needs to be told to do https, at least in this situation:
#!/usr/bin/perl -l
use strict;
use warnings;
use LWP::UserAgent;
my $ua = LWP::UserAgent->new(
ssl_opts => { verify_hostname => 0 },
protocols_allowed => ['https'],
);
my $req = HTTP::Request->new(
GET => 'https://api.flickr.com/services/rest',
);
my $res = $ua->request($req);
print $res->code;
