windows - 如何获得饼干？

Question

使用 WWW::Mechanize 和 HTTP::Cookies 我将如何从服务器的响应中提取 cookie？

#usr/bin/perl 
#MagicLogin.pl

use warnings;
use strict;

use Win32::IE::Mechanize;
use HTTP::Message;
use WWW::Mechanize;
use HTTP::Request::Form;
use HTML::TreeBuilder 3.0;



my $url = 'http://magic.dstcorp.net/MagicDST/';

my $mech = WWW::Mechanize->new(cookie_jar => {});
$mech->agent_alias('Windows IE 6');

my $cookie_jar = new HTTP::Cookies;


my $res = $mech->get($url);
my $tree = new HTML::TreeBuilder;
$tree->parse($res->content);
$tree->eof;

my @forms = $tree->find_by_tag_name('form') or die "No form available";

my $f = HTTP::Request::Form->new($forms[0], $url);
my @fields = $f->allfields;
my $name = $f->name;
my $links = $f->link;
my $buttons = $f->buttons;
my $referrer = $f->referer;

print "Name: ", $name, "\nLink: ", $links, "\nFields: ", @fields,"\nButtons: ", $buttons, "\nReferrer: ", $referrer;

my $response = $mech->request($f->press("ok"));
my $cookie = $cookie_jar->extract_cookies($response);
print $response->content if $response->is_success;

print "Succesfully got url" if $mech->success;

#my $headers = new HTTP::Headers;
#my $cookie = $headers->header('Cookie:');
#print "Cookie:", $headers->referer;

#$mech->get($url);
#my @forms = $mech->forms;


#my $content = $mech->content;
my $output_content = 'MagicLogin.html';


#open Write ,">$output_content";
#print Write $content;

输出：

名称：frmLoginEmbedded
在 MagicLoginTest.pl 第 32 行打印中使用未初始化的值 $link。关联：

字段：按钮：0 在 MagicLoginTest.pl 第 37 行的打印中使用未初始化的值 $referre。

在此先感谢您的帮助。

Answer 1

Mechanize 已经包含一个cookie jar。您无需手动构建它。

use Data::Dumper qw(Dumper);
use WWW::Mechanize qw();
my $m = WWW::Mechanize->new;
$m->get(…);
$m->cookie_jar; # returns a HTTP::Cookies object
# e.g.
print $m->cookie_jar->as_string;
$m->cookie_jar->scan(sub { print Dumper \@_; })

Answer 2

我使用以下代码段来访问 cookie：

my $jar = HTTP::Cookies->new();
my $mech = WWW::Mechanize->new(cookie_jar => $jar);
$mech->get('http://www.example.com');
# $jar now contains any cookies set during the GET
print $jar->as_string(), "\n";
