Re: How do I get variables from ARI Asterisk?

thanks for the advice, and yes I'm confused, I'm newbie in asterisk.

I understand over mistake, the script correct is:

$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL,"http://192.168.56.12:8088/ari/channels");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_USERPWD, "asterisk:asterisk");
curl_setopt( $ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
curl_setopt($ch,CURLOPT_POST, true);

$variables = array("channelId"=>$data->channel->id);
$queryParameter = array("endpoint" => "SIP/201", "app" => "call-center", "variables" => $variables);
curl_setopt($ch,CURLOPT_POSTFIELDS, json_encode($queryParameter));

that is, I used both extension/context/priority and app, I remove "extension/context/priority" and the args's setted :-)

in what contest I use the "variables"? and over all, an example in order to use them?

in document I read:

Body parameter
variables: containers - The "variables" key in the body object holds variable key/value pairs to set on the channel on creation. Other keys in the body object are interpreted as query parameters. Ex. { "endpoint": "SIP/Alice", "variables": { "CALLERID(name)": "Alice" } }

but I don't understand how and when use it... :-(
where are the body parameter?

thanks a lot

 Oggetto: Re:  How do I get variables from ARI Asterisk?

                    I don’t get the channel variables in the StasisStart, you only get the arguments for StasisStart.

Just grab the variable once you have the channel ID:

$this->pest->get("/ari/channels/" . $channelID . "/variable?variable=“ . $variableName);

I think you may be a little confused, however, as you are trying to save the channelId as a variable when you initiate the call. If you want to change the channelId of the call when you initiate it, simply change your $queryParameters to include “channelId” => “blahblah” then you can just reference channel blahblah (or enumerated blahblah) in the future.

I've done:

$ch = curl_init();
			curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
			curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
			curl_setopt($ch, CURLOPT_URL,"http://192.168.56.12:8088/ari/channels");
			curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
			curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
			curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
			curl_setopt($ch, CURLOPT_USERPWD, "asterisk:asterisk");
			curl_setopt( $ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));

			curl_setopt($ch,CURLOPT_POST, true);

$variables = array("channelId"=>$data->channel->id);
			$queryParameter = array("endpoint" => "SIP/201", "extension" => "201", "context" => "oscar", "priority" => "1", "app" => "call-center", "variables" => $variables);

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

	$result=curl_exec($ch);

(where $data->channel->id is datas from "generate an outbound call")

the calling work fine, but in websocket/app "call-center" I haven't got the args, why?

I receive:

{
  "type": "StasisStart",
  "timestamp": "2015-02-19T19:28:25.069+0100",
  "args": [],
  "channel": {
    "id": "asterisk_oscar-1424370499.121",
    "name": "SIP/201-0000003d",
    "state": "Up",
    "caller": {
      "name": "",
      "number": ""
    },
    "connected": {
      "name": "",
      "number": ""
    },
    "accountcode": "",
    "dialplan": {
      "context": "oscar",
      "exten": "",
      "priority": 1
    },
    "creationtime": "2015-02-19T19:28:19.527+0100"
  },
  "application": "call-center"
}

What do I mistake?
thanks
