Hello Monks, I know this is probably something that probably has been asked quite a few times....I have scanned through a lot of documentation ...a lot of queries posted on various groups etc..But still not able to get through this issue with the proxy on my network. Also the requests are Websensed. Here is a sample script I picked up from the code snippets on perl monks .... but this doesnt work...


#!/usr/bin/perl -w

# dget.pl
# pod at tail

use strict;
use LWP::UserAgent;
use Getopt::Long;
use Pod::Usage;
use URI::URL;
use LWP::Debug qw(+);

my ($opt_help, $opt_man);
GetOptions(
  'help!' => \$opt_help,
  'man!'  => \$opt_man,
) or pod2usage(-verbose => 1) && exit;
pod2usage(-verbose => 1) && exit if (defined $opt_help);
pod2usage(-verbose => 2) && exit if (defined $opt_man);


# Begin config parameters
my %parm = (
  url       => shift,
  outfile   => shift, 
  uatimeout => 120,          # seconds before giving up on fetch
  browser   => 'Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.9) Geck
+o/20020310 ',
);
my %proxy = (
  host => 'http://proxy.mycomp.com:8080',    # http://host.dom:port
  id   => 'mynw\mylogin',    # ntdom\userid
  pass => 'mypasswd',    # empty quotes if no proxy auth
);
# End config parameters


unless(defined $parm{url}) {
  print "\n  Ooot - you forgot to provide a URL !\n";
  Ooot(); 
}
unless(defined $parm{outfile}) {
  print "\n  Ooot - your forgot to provide an outfile !\n";
  Ooot(); 
}
print "\n  Fetching $parm{url}...\n";


my $ua = new LWP::UserAgent;
$ua->agent($parm{browser});
$ua->timeout($parm{uatimeout});
$ua->proxy(http => "$proxy{host}") if (defined $proxy{host}); 
$parm{url} = new URI::URL($parm{url});
my $req    = new HTTP::Request "GET" => ($parm{url});
$req->proxy_authorization_basic
  ($proxy{id}, $proxy{pass}) if (defined $proxy{id});


my $res = $ua->request($req);
if ($res -> is_success) {
  my $rescont = $res->content;
  open (OUT, ">$parm{outfile}")
    or die "Error opening $parm{outfile} for write: $!";
  print OUT $rescont;
  close OUT
    or die "Error closing $parm{outfile}: $!";
}
else {
  my $resmsg = $res->message;
  print "Error fetching $parm{url}:\n  $resmsg\n\n";
  exit;
}


print "  Done!  Page saved at '$parm{outfile}'\n\n";



sub Ooot {
  print
    "\n  dget.pl --help",
    "\n  dget.pl --man",
    "\n",
    "\n  LWP      $LWP::VERSION",
    "\n  Perl     $]",
    "\n  OS       $^O",
    "\n  Program  $0",
    "\n\n",
    ;
  exit;
}



Outputs the following :

D:\testperl>perl dget.pl http://google.com out.txt

  Fetching http://google.com...
LWP::UserAgent::new: ()
LWP::UserAgent::proxy: http http://proxy.mycomp.com:8080

Please guide me to the right issue behind this.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
