LWP::UserAgent介绍3 -> cookie设置

  use LWP::UserAgent;
  use HTTP::Cookies;
 
  my $ua = LWP::UserAgent->new;
  $ua->cookie_jar(HTTP::Cookies->new(
     file => "cookies.txt",
     autosave => 1));
 
  my $req = HTTP::Request->new(GET => "http://www.example.com/");
 
  my $res = $ua->request($req);
  print $res->status_line;
#用HTTP::Cookies来创建cookie保存的地方

#或者可以如下所示

use LWP::UserAgent;
use HTTP::Cookies;
$cookie_jar = HTTP::Cookies->new(
        file => "/home/perl/cookies.dat",
        autosave => 1,
);
$ua->cookir_jar($cookie_jar);
#还可以这样
$ua->cookie_jar({ file => "$ENV{HOME}/.cookies.txt" });
#注意这里是cookie_jar参数要求是个字典

还有， 如果你是想在发送请求时一起发送指定cookie, 可以这样：

use LWP::UserAgent;
my $ua = LWP::UserAgent->new;
 
my $req = HTTP::Request->new(GET => 'http://www.example.com/');
$req->header('Cookie' => "key1=value1;key2=value2");
#这个header可参考HTTP::Headers模块
my $res = $ua->request($req);
print $res->status_line
