[smilingsagar]

I am a new bee in Perl. I am trying to download pdf file from UN website, using mechanize. http://documents-dds-ny.un.org/doc/UNDOC/GEN/N08/588/39/pdf/N0858839.pdf?OpenElement Please let me know more about html headers using mechanize.

use strict; 
use warnings; 
use LWP::Simple; 
use WWW::Mechanize;
use Compress::Zlib;

# Create a new instance of WWW::Mechanize
my $mechanize = WWW::Mechanize->new(autocheck => 1);
$mechanize->cookie_jar(HTTP::Cookies->new);

my $url = 'http://documents-dds-ny.un.org/doc/UNDOC/GEN/N08/588/39/pdf
+/N0858839.pdf?OpenElement'; 
my $file = 'test.pdf';
#getstore($url,$file);



$mechanize->cookie_jar(HTTP::Cookies->new);
$mechanize->get($url);
my $response = $mechanize->response();
for my $key ( $response->header_field_names() ) {
    print $key, " : ", $response->header( $key ), "\n";
}

my $dest = $mechanize->response->content;
if($mechanize->response->header("Content-Encoding") eq "gzip")
{
    $dest = Compress::Zlib::memGunzip($dest);
    $mechanize->update_html($dest);
}
$mechanize->get($url,":content_file" => $file);
print $mechanize->content();

sin 1) you did not ask a question

sin 2) you pretend to be a new bee , can you tell us about older bees ? also , if you're a bee how come you can write ? are you bees that smart ?

sin 3) it's 100% that you're working on this project , why exactly did you disclose where you're taking the data from ? and how do you respect us monks by asking us to do your work for you ? you bee !
