【问题描述】:
我正在尝试使用 WWW:Mechanize 连接到 https 网站。当我运行我的脚本时,我收到如下所示的错误“网络无法访问...”消息。
为什么它使用 http.pm 而不是该目录中的 https.pm?下面的来源和错误...
#!/usr/bin/env perl
use LWP::UserAgent;
use LWP::Protocol::https;
use WWW::Mechanize;
$ENV{HTTPS_DEBUG} = 1;
print "WWW::Mechanize: ", $WWW::Mechanize::VERSION, "\n";
print "LWP : ", $LWP::UserAgent::VERSION, "\n";
print "LWP::Protocol::https : " , $LWP::Protocol::https::VERSION, "\n";
my $mech = WWW::Mechanize->new();
my $ua = LWP::UserAgent->new;
$ua->protocols_allowed(['https']);
$mech->add_handler("request_send", sub { shift->dump; return });
$mech->add_handler("response_done", sub { shift->dump; return });
my $url ="https://www.cpan.org";
$mech->get( $url );
my @links = $mech->links();
for my $link ( @links ) {
printf "%s, %s\n", $link->text, $link->url;
}
输出:
WWW::Mechanize: 1.75
LWP : 6.13
LWP::Protocol::https : 6.06

我无法通过浏览器使用
https连接到https://www.cpan.org,但可以使用您的脚本连接到https://metacpan.org/。我猜 CPAN 不支持https。
