您的示例中断了,但是您似乎想要获取资源,提取链接并可能要执行其他操作。我建议您让Mojolicious为您执行此操作。它可以获取资源,解析HTML(dom),提取其他链接(在map中),然后选择具有正确方案的链接(第一个grep):

use v5.10;

use Mojo::UserAgent;

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

my @queue = ( $ARGV[0] );

my %Seen; # don't process things we've already seen
while( my $this = shift @queue ) {
    say "Processing $this";

    my $tx = $ua->get( $this );

    my @links = $tx->result
        ->dom
        ->find( 'a' )
        ->map( attr => 'href' )
        ->grep( sub { Mojo::URL->new($_)->scheme =~ /https?/ } )
        ->grep( sub { ! $Seen{$_} } )
        ->each;

    say "\t", join "\n\t", @links;

    push @queue, @links;
    }

我在Mojolicious Web Clients中用很多示例编写了所有这些内容。
