ZenPacks, JSON API, and Integrations

Hi,

Premise:
I have a class in my Laravel 5.5 application to interface itself  to Zenoss 4.2.5 server.
In the application controller I call the getDeviceInfo() method after creating the zenoss object.
This is the code for class Zenoss:

This is the method code of laravel controller:

The problem
I expect it to return the information passed in the keys argument in the getDevices() method of the JSON API invoked by the

That is:

But it returns only the uid of the three devices loaded in my Zenoss LAB:

There seems to be a mistake. But I don't understand which one.
Question:
Where am I doing wrong?

I tried the curl command from another linux server:
curl -u "admin:password" -X POST -H "Content-Type: application/json" -d '{"action": "DeviceRouter", "method": "getDevices", "data": [{"uid": "/zport/dmd/Devices/"}], "tid": 1}' http://10.xxx.xxx.xxx:8080/zport/dmd/device_router

and it works!
I changed my code:
in my class from:
to:

and in my class from:
to:

It return a zenoss error page to report the error details .

Where am I doing wrong again?

thanks

Hi,

Premise:
I have a class in my Laravel 5.5 application to interface itself  to Zenoss 4.2.5 server.
In the application controller I call the getDeviceInfo() method after creating the zenoss object.
This is the code for class Zenoss:

class Zenoss

{

    private $tmp;

    private $protocol;

    private $address;

    private $port;

    private $username;

    private $password;

    private $cookie;

    function __construct($address,$username='admin',$password='password',$port='8080',$tmp='/tmp/',$protocol='http')

    {

        if(!is_writable($tmp))

                throw new Exception('Specified cookie file directory does not exist or is not writable.');

        

        $this->address = $address;

        $this->username = $username;

        $this->password = $password;

        $this->port = $port;

        $this->tmp = $tmp;

        $this->protocol = $protocol;

        $this->cookie = $tmp."zenoss_cookie.txt";

    }

   

    private function zenQuery(array $data, $uri)

    {

        $data['tid'] = 1;

        $data['type'] = "rpc";

        $ch = curl_init("{$this->protocol}://{$this->address}:{$this->port}/zport/acl_users/cookieAuthHelper/login");

        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

        curl_setopt($ch, CURLOPT_USERPWD, "{$this->username}:{$this->password}");

        curl_setopt($ch, CURLOPT_COOKIEFILE, $this->cookie);

        curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json; charset=utf-8'));

        curl_exec($ch);

        curl_setopt($ch, CURLOPT_URL, "{$this->protocol}://{$this->address}:{$this->port}{$uri}");

        curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));

        $result = curl_exec($ch);

        if($result===false){

            Log::info('Zenoss::zenQuery - curl_exec error: '.curl_error($ch));

        }

//            throw new Exception('Curl error: ' . curl_error($ch));


        curl_close($ch);

        

        Log::info($result);

        print_r($result);

        //return back();

    }

    public function getDevices($start=0, $limit=100, $sort="name", $dir="ASC")

    {

        Log::info('Zenoss::getDevices');

        $json_params = array();

        $json_data = array();

        $json_main = array();

        $json_keys = array("name", "ipAddress", "productionState", "groups", "location");

        

        $json_data['keys'] = $json_keys;

        $json_data['dir'] = $dir;

        $json_data['limit'] = $limit;

        $json_data['sort'] = $sort;

        $json_data['start'] = $start;

        $json_data['params'] = $json_params;

        $json_main['action'] = "DeviceRouter";

        $json_main['method'] = "getDevices";

        $json_main['data'] = $json_data;

        return $this->zenQuery($json_main, '/zport/dmd/Devices/getSubDevices');

    }
}

This is the method code of laravel controller:

public function list_all_devices(){

        Log::info('ZenosController::list_all_devices');

        $zenoss = new Zenoss('10.10.10.10');

        $devices = $zenoss->getDevices();

    }

The problem
I expect it to return the information passed in the keys argument in the getDevices() method of the JSON API invoked by the

getDevices($start=0, $limit=100, $sort="name", $dir="ASC") method of the class Zenoss.

That is:

$json_keys = array("name", "ipAddress", "productionState", "groups", "location");

But it returns only the uid of the three devices loaded in my Zenoss LAB:

[2020-11-24 08:16:30] local.INFO: [<Device at /zport/dmd/Devices/Network/Router/Cisco/devices/c3750.xx-xxxxxx-ull-01>, <Device at /zport/dmd/Devices/Server/Linux/devices/10.xxx.10.xxx>, <Device at /zport/dmd/Devices/Server/Linux/devices/ZenLab>]

There seems to be a mistake. But I don't understand which one.
