Question

我正在尝试使用WWW连接到https网站：Mechanize。当我运行我的脚本时，我收到错误＆＃34;网络无法访问...＆＃34;消息如下所示。

为什么它使用http.pm而不是https.pm，它存在于该目录中？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
GET https://www.cpan.org
Accept-Encoding: gzip
User-Agent: WWW-Mechanize/1.75

Answer 1

my $ url =＆＃34; https://www.cpan.org" ;;

当脚本到达站点时出现问题＃1：使用浏览器进行检查。惊喜：它在ERR_CONNECTION_REFUSED的浏览器中失败。这告诉你该网站也没有浏览器，所以为什么它应该与脚本一起使用。

为什么它使用http.pm而不是https.pm，它存在于该目录中？

因为https只是SSL隧道内的http，所以LWP中的https支持会大量使用http支持。因此，您从http.pm。
