The LWP::UserAgent module can be used to issue a curl request and return the response. If basic authentication is needed for the URL being requested, authorization_basic can be used.

For example, let's say a request to www.example.com/api should return "Hello World", and Dumper can be used to display the response.

#!/usr/bin/perl
use strict;
use warning;
use LWP::UserAgent;
use Data::Dumper;

my $ua = LWP::UserAgent->new;
my $request = HTTP::Request->new(GET => "http://www.example.com/api");
$request->authorization_basic( "john.doe", "itsasecret" );
my $response = $ua->request($request);

print Dumper $response;

Something like this should be returned.

$VAR1 = bless( {
                 '_protocol' => 'HTTP/1.1',
                 '_content' => 'Hello World',
                 '_rc' => '200'
});

And here is how you would print only the content.

print $response->decoded_content;
