Hi David

I haven't used any of the REST PERL packages as I've tried to use only the installed software for SE for my scripting.  This is no doubt something that each client/programmer will have a view on.  Therefore I simply use a PERL system call and CURL.  I would not call this production or professional grade solution but it gets the job done.  If that helps, I'm happy to share a script 

Cheers

Hi Ed,

Happy to look at your CURL code - might help we see what's going on - or give me a base to work from.

Currently I have the simplest of Perl scripts trying to get a simple of assets (small steps).

I'm getting "500" error being returned.

500 Can't connect to dco.rhino-hosting.com:443 (Bad file descriptor) at simple.pl line 23.

This is against one of the the training servers.

use strict;
use warnings;
use LWP::UserAgent ();
 
my $ua = LWP::UserAgent->new;
$ua->timeout(10);
$ua->env_proxy;

$ua->credentials(
 'dco.rhino-hosting.com:443',
 'ISXO',
 'user' => 'password'
);

$ua->default_header( Accept => 'application/json' );
 
my $response = $ua->get('https://dco.rhino-hosting.com/api/v8.1/assets');
 
if ($response->is_success) {
 print $response->decoded_content; # or whatever
}
else {
 die $response->status_line;
}

Thanks,

dave

Try HTTP rather than HTTPS - just as a test

+1 on this comment.

Disable the auto routing from http to https via webmin if you are testing via http.

That's done the trick - thanks!

And changed the authorisation to Basic.

Code now looks like this (in case anyone else is interested).

#!/usr/bin/perl

use strict;
use warnings;
use LWP::UserAgent;
use Data::Dumper;
use JSON;

my $address = "dco.rhino-hosting.com";
my $port = 80;
my $username = "user";
my $pass = "password";

my $url = "http://$address:$port/api/v8.1/assets";
print $url . "\n";

my $browser = LWP::UserAgent->new('Mozilla');
my $req = HTTP::Request->new(GET => $url);
$req->authorization_basic($username, $pass);

my $res = $browser->request($req);
print Dumper($res) . "\n";

my $response = from_json($res->decoded_content);
print Dumper($response) . "\n";
