如何使用LWP设置User-Agent？

Question

我有Perl和LWP书籍,但如何设置用户代理字符串？

这就是我所拥有的:

use LWP::UserAgent;
use LWP::Simple; # Used to download files

my $u = URI->new($url);
my $response_u = LWP::UserAgent->new->get($u);
die "Error: ", $response_u->status_line unless $response_u->is_success;

任何建议,如果我想像LWP::UserAgent我在这里一样使用？

来自LWP食谱:

  use LWP::UserAgent;
  $ua = new LWP::UserAgent;
  $ua->agent("$0/0.1 " . $ua->agent);
  # $ua->agent("Mozilla/8.0") # pretend we are very capable browser

  $req = new HTTP::Request 'GET' => 'http://www.sn.no/libwww-perl';
  $req->header('Accept' => 'text/html');

  # send request
  $res = $ua->request($req);
