host.get fails under 1.8 api?

[cirrhus9.com]

Hello:
I am just starting to explore some basic remote information gathering from our zbx 1.8.10 host.

I found an example on the blog at Getting started with Zabbix API and I can authenticate fine.
so I move on to Getting list of hosts on the same page but it returns no hosts.

#!/usr/bin/perl

use 5.010;
use strict;
use warnings;
use JSON::RPC::Client;
use Data::Dumper;

# Authenticate yourself
my $client = new JSON::RPC::Client;
my $url = 'http://some.ip.address/zabbix/api_jsonrpc.php';
my $authID;
my $response;

my $json = {
jsonrpc => "2.0",
method => "user.login",
params => {
user => "user",
password => "secret"
},
id => 1
};

$response = $client->call($url, $json);

# Check if response was successful
die "Authentication failed.\n" unless $response->content->{'result'};

$authID = $response->content->{'result'};

# Get list of all hosts using authID

$json = {
jsonrpc=> '2.0',
method => 'host.get',
params =>
{
output => ['hostid','name'],# get only host id and host name
sortfield => 'name',        # sort by host name
},
id => 2,
auth => "$authID",
};
$response = $client->call($url, $json);

# Check if response was successful
die "host.get failed\n" unless $response->content->{result};

print "List of hosts\n-----------------------------\n";
foreach my $host (@{$response->content->{result}}) {
print "Host ID: ".$host->{hostid}." Host: ".$host->{name}."\n";
} 

I do get

List of hosts
-----------------------------

Can someone help me out and show me the error of my ways?

Thank you.

Edit: The topic is not accurate, it does NOT fail, it simply returns no hosts.
Sorry about that.

is bump allowed?

I don't know the API really, but it seems like the request options are invalid for 1.8 - or at the very least they don't return anything for me on 1.8.11.

When I changed the request to the following, I got lots of info back:

$json = {
jsonrpc=> '2.0',
method => 'host.get',
params =>
{
output => 'extend', #['hostid','name'],
sortfield => 'host',   # 'name'
},
id => 2,
auth => "$authID",
};

If you want to print all of the response, use the following line:

print Dumper($response->content);

Thank you!

$json = {
jsonrpc=> '2.0',
method => 'host.get',
params =>
{
output => 'extend', #['hostid','name'],
sortfield => 'hostid'.'host',   # 'name'
},
id => 2,
auth => "$authID",
};
$response = $client->call($url, $json);
Dumper($response->content);

# Check if response was successful
die "host.get failed\n" unless $response->content->{result};

print "List of hosts\n-----------------------------\n";
foreach my $host (@{$response->content->{result}}) {
print "Host ID: ".$host->{hostid}." Host: ".$host->{host}."\n";
}

works from here.
