使用LWP :: UserAgent时不会保存Cookie

Question

我正在尝试使用cookie,LWP::UserAgent但它们没有保存在文本文件中.我究竟做错了什么？

use v5.16;
use strict;
use warnings;
use Data::Dumper;

use LWP::UserAgent;
use HTTP::Cookies;
use Net::SSL ();

my $cookie_jar = HTTP::Cookies->new( 
    file => 'lwp_cookies.txt',
    autosave => 1,
);

my $ua = LWP::UserAgent->new(
    ssl_opts   => { verify_hostname => 0 },
    cookie_jar => $cookie_jar,
);

my $auth_url = 'https://my.site.url/path/authenticate';
use HTTP::Request::Common qw(GET);
my $req = HTTP::Request->new(GET => $auth_url);
$req->authorization_basic('username', 'password');

$ua->request($req);
say Dumper( \$cookie_jar );

转储的数据如下所示:

$VAR1 = \bless( {
   'autosave' => 1,
   'COOKIES' => {
          'my.site.url' => {
                '/' => {
                     'BLAH_COOKIE_KEY' => [
                         0,
                         'very_long_string',
                         undef,
                         1,
                         undef,
                         undef,
                         1
                       ]
                   }
              }
        },
   'file' => 'lwp_cookies.txt'
 }, 'HTTP::Cookies' );

而lwp_cookies.txt只是有这样的:

#LWP-Cookies-1.0

我和Strawberry Perl一起赢了.

试着发一个:

$cookie_jar->save

此外,Cookie可能已过期,或请求被丢弃,因此,也可以将您$cookie_jar的ignore_discard设置为1:

my $cookie_jar = HTTP::Cookies->new( 
    file => 'lwp_cookies.txt',
    autosave => 1,
    ignore_discard => 1,
);
