Perl WWW::Mechanize — Authentication Error GETing URL

问题

I'm trying to fill out a web form using the Mechanize library of Perl.

Whenever I enter the URL into the search box it prompts the below message, and I can manually login sucessfully.

However, when I run the below script, I get the following error:

How do I correctly fill in the first Authentication Box credentials using my $mech object?

my $mech = WWW::Mechanize->new( 'keepalive' => 1 );

my $url = "http://URL/I/NEED/TO/ACCESS";
my $username = "username";
my $password = "password";

$mech->credentials($username, $password);
$mech->get($url);          <----------------- ERROR (LINE 93)

EDIT:

Here are the results of running wget on the requested site

回答1:

With older versions of Mechanize you could subclass the WWW::Mechanize package and provide your own credentials routine:

package MyMech;

use vars qw(@ISA);
@ISA = qw(WWW::Mechanize);

sub get_basic_credentials {
  my ($self, $realm, $uri) = @_;
  return( "user", "password" );
}

Then in your program use this package instead of WWW::Mechanize:

package main;

my $mech = MyMech->new();
$mech->get( $url );

Update

You've updated your question to indicate the requirement of NTLM authentication. Check out LWP::Authen::Ntlm on CPAN.
