LWP::UserAgent介绍3 -> cookie设置

 1   use LWP::UserAgent;
 2   use HTTP::Cookies;
 3
 4   my $ua = LWP::UserAgent->new;
 5   $ua->cookie_jar(HTTP::Cookies->new(
 6      file => "cookies.txt",
 7      autosave => 1));
 8
 9   my $req = HTTP::Request->new(GET => "http://www.example.com/");
10
11   my $res = $ua->request($req);
12   print $res->status_line;
13 #用HTTP::Cookies来创建cookie保存的地方

#或者可以如下所示

 1 use LWP::UserAgent;
 2 use HTTP::Cookies;
 3 $cookie_jar = HTTP::Cookies->new(
 4         file => "/home/perl/cookies.dat",
 5         autosave => 1,
 6 );
 7 $ua->cookir_jar($cookie_jar);
 8 #还可以这样
 9 $ua->cookie_jar({ file => "$ENV{HOME}/.cookies.txt" });
10 #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：

1 use LWP::UserAgent;
2 my $ua = LWP::UserAgent->new;
3
4 my $req = HTTP::Request->new(GET => ‘http://www.example.com/‘);
5 $req->header(‘Cookie‘ => "key1=value1;key2=value2");
6 #这个header可参考HTTP::Headers模块
7 my $res = $ua->request($req);
8 print $res->status_line
