Problems with controlling my squeezeboces via my homepage?!

First find some sample code for PHP doing JSON/RPC on the server side.
Eg. http://jsonrpcphp.org. Familiarize yourself with this method.

Then get familiar with LMS' implementation. It's easiest to eg. fire up
firebug in firefox and monitor what is going on when you browse the LMS
web UI. In the console you'd see all the requests going back and forth.
Documentation of the commands and queries available you'll find in
http://pi:9000/html/docs/cli-api.html (or whatever your server)

Now everything is a bit clearer.
Will have a look into this. thx

Hi,

something I come across while studying the CLI/JSON-RPC stuff was the controlling of the plugins, to be exact the SqueezeCloud-plugin.

Using the http-request method, the plugin can be controlled like this:

anyurl?p0=playlist&p1=add&p2=soundcloud%3A%2F%2F106399621&p3=Falscher Hase at Fuchsbau Festival - 16-08-2013&player=MAC-adress

How should this command look like, if I use the CLI/JSON API??? :S

> --------------------

This would become something like

["00:02:40:....", ["playlist", "add", "soundloud:....", "Falscher hase..."]]

Check http://yourserver:9000/html/docs/cli...playlist%20add for
the command reference. It's pretty much putting p0-p99 into a list of
the json object.

Hi,

I found another (better?) solution. I just used the curl-function of php to control the LMS. Looks like this now:

$JsonString = '$Json = json_encode(array("id" => 1, "method"=> "slim.request","params"=> array(';

switch ($_POST["p0"]) {
	case 'pause' :
	case 'play' :
		$JsonString .= $playerId.',array("pause"))));';
		break;

	case 'rewind':
		$JsonString .= $playerId.',array("time","-10"))));';
		break;
...
}
eval($JsonString);

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $LmsUrl);
curl_setopt($ch, CURLOPT_USERPWD, $User.":".$Pw);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $Json);

// $output contains the output string
// 
$output = curl_exec($ch);
// close curl resource to free up system resources
curl_close($ch);
echo $output;

and this will be called via an ajax-function by the client as follows:

$( ".LmsButton" ).click(function() {
	var blub = $(this).attr('id');
	$.ajax({
		url: '/JsonRpc.inc.php',
		type: 'POST',
		dataType: 'json',
		data: {p0: blub},
		success: function(data) {
		}
	})	
});

Hope this will help somebody.


But I have another question, which came into my mind. Is it possible to send more than one command to the LMS, like

["00:02:40:....", ["playlist", "add", "soundloud:....", "Falscher hase..."],["playlist", "add", "soundloud:....", "Guter Esel..."],["play"]];

[pippin]

Yes, but you need to send complete commands, including the target player. Just add them to the array.

[SunBob]

Hi Pippin,

I think I don't get it.

What I tried

{"id":1,"method":"slim.request","params":[<playerid>,["mode","?"],<playerid>,["artist","?"],<playerid>",["title","?"]]}

resulting in:

{"params":["00:04:20:1e:e1:11",["mode","?"],"00:04:20:1e:e1:11",["artist","?"],"00:04:20:1e:e1:11",["title","?"]],"method":"slim.request","id":1,"result":{"_mode":"pause"}}

is obvious wrong, but I don't know how this should look like.

Could you please post an example. Thx in advance.

[pippin]

Yes, you need to send an array of complete JSON/RPC commands:

[
    {
        "id":1,
        "method":"slim.request",
        "params":[<playerid>,["mode","?"]]
    },
    {
        "id:2,
        "method":"slim.request",
        "params":[<playerid>,["artist","?"]]
    },...
]

That said: I'm no longer 100% sure that this works with JSON/RPC, actually I believe I have never done it this way. I do it with cometd but that protocol explicitly allows for command arrays.

Now the question is: do you really need to serve up that page from
Apache? You could use LMS' built-in web server to provide that page instead.

Hi

Can you point me in the direction of how I might get LMS to serve up my HTML pages (where do I need to put them, etc)?

Thanks
