LWP Credentials

js1 has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

I'm having a problem with LWP. Here's my script:

!/opt/perl-5.8.0/bin/perl

use LWP;
use LWP::Debug qw(level); level('+');

my $browser = LWP::UserAgent->new;
$browser->credentials( 'csgl02:8082', 'Blue Coat Proxy SG', 'u452359' 
+=> 'abc123');

my $url='https://csgl02:8082/Secure/Local/console/documentation.htm';

my $response = $browser->get($url);

die "Error: ", $response->header('Blue Coat Proxy SG') || 'Error acces
+sing',
    #('WWW-Authenticate' is the realm-name)
    "\n ", $response->status_line, "\n at $url\n Aborting"
   unless $response->is_success;

print $response->content;

exit;

This is what happens when I try to run it:

smpd9$ ./test.pl
LWP::UserAgent::new: ()
LWP::UserAgent::request: ()
LWP::UserAgent::send_request: GET https://csgl02:8082/Secure/Local/con
+sole/documentation.htm
LWP::UserAgent::_need_proxy: Not proxied
LWP::Protocol::http::request: ()
LWP::Protocol::collect: read 25 bytes
LWP::UserAgent::request: Simple response: Unauthorized
LWP::UserAgent::request: ()
LWP::UserAgent::send_request: GET https://csgl02:8082/Secure/Local/con
+sole/documentation.htm
LWP::UserAgent::_need_proxy: Not proxied
LWP::Protocol::http::request: ()
LWP::Protocol::collect: read 41 bytes
LWP::UserAgent::request: Simple response: Unauthorized
Error: Error accessing
 401 Authentication Required
 at https://csgl02:8082/Secure/Local/console/documentation.htm
 Aborting at ./test.pl line 32.
smpd9$

I'm sure the credentials are right as I have tested in a browser. Any ideas what might be going wrong or how I can get some more info?

Thanks,
js1.

Try turning on the debugging of the requests and responses. `use LWP::Debug qw(level); level('+comms');` [download] Compare the output to a successful login from a browser. livehttpheaders is a Mozilla extension to record the HTTP protocol. Things to look for are that the realm is right. See if the password is the same.	[reply] [d/l]

I didn't have much luck with that. I used +comms but that didn't give me any info: `smpd9$ ./test.pl Error: Error accessing 401 Authentication Required at https://csgl02:8082/Secure/Local/console/documentation.htm Aborting at ./test.pl line 32. smpd9$` [download] Here's an extract from HTTP Live Headers:: https://csgl02:8082/Secure/Local/console/documentation.htm GET /Secure/Local/console/documentation.htm HTTP/1.1 Host: csgl02:8082 User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6) Ge +cko/20040206 Firefox/0.8 Accept: application/x-shockwave-flash,text/xml,application/xml,applica +tion/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,video/x-mng,image/png +,image/jpeg,image/gif;q=0.2,/;q=0.1 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,;q=0.7 Keep-Alive: 300 Connection: keep-alive HTTP/1.x 401 Authentication Required WWW-Authenticate: Basic realm="Blue Coat Proxy SG" refresh: 0;URL="/Secure/Local/console/logout.htm" Server: BlueCoat-Security-Appliance Pragma: no-cache Cache-Control: no-cache Set-Cookie: BCSI_MC=267053511:1; path=/ Content-Type: text/plain ---------------------------------------------------------- https://csgl02.:8082/Secure/Local/console/documentation.htm GET /Secure/Local/console/documentation.htm HTTP/1.1 Host: csgl02:8082 User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6) Ge +cko/20040206 Firefox/0.8 Accept: application/x-shockwave-flash,text/xml,application/xml,applica +tion/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,video/x-mng,image/png +,image/jpeg,image/gif;q=0.2,/;q=0.1 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,;q=0.7 Keep-Alive: 300 Connection: keep-alive Authorization: Basic dTc1MjM1OTpwdXNhbjI2 Cookie: BCSI_MC=267053511:1 HTTP/1.x 200 OK Server: BlueCoat-Security-Appliance Pragma: no-cache Cache-Control: no-cache Set-Cookie: BCSI_MC=267053558:0; path=/ Content-Length: 9244 Content-Type: text/html ---------------------------------------------------------- [download] Can you spot what I'm doing wrong? js1.
