litemotiv Wrote:Thanks for your reply Montellese. Unfortunately, replacing all the single quotes still gives a parse error.
The mootools request object is also using single quotes internally though, so i'm not sure if there still is a problem there in some way: https://github.com/mootools/mootools-core/blob/master/Source/Request/Request.js
I feared as much as what you provide for the json rpc request is javascript syntax and there the single quote is alright.
The question is how mootools formats the json object you provide it with and how it is sent to XBMC. Can you use something like Firebug to look at the actually sent HTTP request? This might help in locating the problem.
EDIT: Just had another thought. How do you tell mootools where XBMC is located? Your url only says "/jsonrpc" but there is no IP or something like that. But as I don't know mootools anymore (last time I used it it was in the very first beta
) this is simply a shot in the dark.

Firebug only says it is doing a post with the following data:
Code:
[application/x-www-form-urlencoded]
id 1
jsonrpc 2.0
method Files.GetSources
params[media] video
[Source]
jsonrpc=2.0&method=Files.GetSources&id=1¶ms[media]=videoSo no sign of any quotes there. I'm pretty sure that the url is alright though..

I think the problem is this: "application/x-www-form-urlencoded"
Looks like mootools changes your whole request into an url encoded format as shown at the end:

jsonrpc=2.0&method=Files.GetSources&id=1¶ms[media]=videoCode:

You're right, the conversion to querystring which mootools does by default is the problem... I've used a workaround for this which seems to work, but i'm going to nag the mootools developers a little to change this for json requests.
Thanks for your help!

I'd say they should convert it to a query string if you use GET but leave it as a jso object if you use POST. D'ont know if it would make sense for XBMC to support GET requests as well...

It may be be arguably sane, i.e. it may be no problem accepting GET also, but jsonrpc spec regarding http communication states post to be used for the json object. I know some servers accept RESTless stuff though.

I just checked and the JSON RPC 1.1 specification has a definition for HTTP GET (http://json-rpc.org/wd/JSON-RPC-1-1-WD-20060807.html#GetProcedureCall). But it states that HTTP GET does not allow json objects as parameters which is kind of a huge drawback.

I would be pretty nice to accept json objects through post, and querystrings through get?

Hi all,
I'm having a problem using the TCP transport via PHP's sockets implementation. I am using the following code:
PHP Code:
$buffer = '';
do {
$data = socket_read($this->socket, 1024);
if (socket_last_error($this->socket) == 104) {
throw new XBMC_RPC_ClientException('Connection reset by peer');
break;
}
if (!empty($data)) {
$buffer .= $data;
} elseif ($data === '') {
throw new XBMC_RPC_ClientException('Socket closed unexpectedly');
break;
}
} while (!empty($data));
However this produces an infinite loop. If I check the data from socket_read, I see that I'm getting the same data each time, ie the first 1024 bytes of the response, so the loop never terminates. Is there something I'm doing wrong here?
EDIT: Seems its not an infinite loop but rather the socket is blocking. If I use socket_recv with the MSG_DONTWAIT flag I get an error:
Code:
unable to read from socket [11]: Resource temporarily unavailableEDIT2: Never mind. I guess XBMC is not sending any kind of EOF character or otherwise to indicate the end of a message so the socket blocks while it's waiting. I ended up just counting the number of { and } characters in the response, though it seems messy to me.

This was probably asked before, but is there or will there be a sortmethod for the audiolibrary available ?
- litemotiv - 2011-01-09
I'm also experiencing some kind of strange bug: when i retrieve AudioPlaylist.GetItems while audio is playing, XBMC dies. The music keeps playing until the song is finished, then X (linux here) crashes and drops to the shell.
Any ideas on how to debug this? All other rpc calls work without problems.

Every call to get a list has a sorting option you may use.

I'll see if the problem exists on Windows and report back.

I can reproduce it 100% so far, xbmc completely crashes (happens with all songs/albums/etc). Both with Library and file browser.
This is on Arch linux, kernel 2.6.36 and kernel 2.6.37, xbmc 10.0 release version.

I can't seem to get it working, what would be the sortmethod parameters for retrieving the album or artists lists, ordered by name/title? Do they use the database fields, or something else?
I've tried stuff like this:
Code:
{"jsonrpc":"2.0","method":"AudioLibrary.GetAlbums","id":1,"params":{"sortmethod":"strAlbum","start":0,"end":10}}
