Videoroom REST API call

[Mohamed Sadok Ben Jazia]

Hello,

I want to call videoroom API in a PHP script, i can't find the right parameters to send. I always getting something like this { "janus": "error", "error": { "code": 454, "reason": "JSON error: on line 1: '[' or '{' expected near '-'" } }

I did the same thing (Create, destroy, list) in javascript API and it's working well.

I want an example, or a right request(url and parameters) to use videoroom REST API.

Thx

This is a javascript example. I already make it work. I need a server side example

For example i used this url : http://46.16.200.66:8188/janus/

And this Json data 

{

        "janus" : "list",

        "plugin" : "janus.plugin.videoroom",

        "transaction" : "1905767215"

}

I get 0 NO RESPONSE

There's no difference in talking to Janus from a browser or from a server, the protocol and exchanged messages are the same.

Study the messages that are exchanged in that demo, and more in general the protocol documentation too.

It's about integrating janus in a web app, using external database.

Calling Janus from a server is important.

[Lorenzo Miniero]

Yes, I know, and that's what we and other people do :-)

What I mean is you can study the communication that is done in the browser via JavaScript, as the messages you'd send from a server are the same. You create sessions, handles and the like the same way, and the same applies to requests/responses events from plugins.

I created this code for listing room list..

$server='http://server_ip:8088/janus/';

$data='{"janus":"create","transaction":"zKuHZzgGGuwb"}';

$result=CallAPI('POST',$server,$data);

$instance_id=json_decode($result, true)["data"]["id"];

$server2='http://server_ip:8088/janus/'.$instance_id;

$data2='{"janus":"attach","plugin":"janus.plugin.videoroom","transaction":"iytlPUfRNS8G"}';

$result=CallAPI('POST',$server2,$data2);

$plugin_id=json_decode($result, true)["data"]["id"];

$server3='http://server_ip:8088/janus/'.$instance_id.'/'.$plugin_id;

$data3='{janus: "message", body: {request: "list"}, transaction: "Zc0V36KBCKiV"}';

$result=CallAPI('POST',$server3,$data3);

var_dump(json_decode($result, true));

the two first request works good and return a valid result.

The third one returns   

{ ["janus"]=> string(5) "error" ["error"]=> array(2) { ["code"]=> int(454) ["reason"]=> string(58) "JSON error: on line 1: string or '}' expected near 'janus'" } }

Did i miss something, what solution can be used for this

[Lorenzo Miniero]

In JSON attribute names must we wrapped in quotes.

Hello,

I reimplemented myself a REST api call using PHP/javascript based on your version of janus.js

You can use securely the admin-api

Feel free to publish on the ressource page.

Thanks for sharing! I'll update the docs.

This still requires clients to pro-actively refresh sessions, right? IIRC with php you cannt have something lingering in the background that keeps the session state active for you.

It seems to be working well with the examples.

Anycase, all updates are welcome.
