The Info Query allows for the extraction of information about the state of the server via a REST API call.

Usage and Examples

Assuming your server runs on localhost and port 8080, you can execute an info query accessing the following url:

http://localhost:8080?q=PARAMETER 

where PARAMETER can take any of the following values:

channels

Returns high-level information for every active channel.

Call:

http://localhost:8080?q=channels 

Return value:

{ "ultimatum": { "sockets":{"sio": true, "direct": true }, "accessDeniedUrl":"/ultimatum/unauth.htm", "verbosity":100, "getFromAdmins":true, "enableReconnections":true, "defaultChannel":false, "name":"ultimatum", "roomCounter":2, "gameName":"ultimatum", "open":true } }

games

Returns detailed information about the game played in every channel.

Call:

http://localhost:8080?q=games 

Return value:

{ "ultimatum": { "dir": "path/to/dir/game", "info": { }, // Content of package.json "settings": { // As in game.settings.js "standard": { }, "pp": { } }, "treatmentNames": ["standard","pp"], "setup": { }, // As in game.setup.js "stager": { }, // Game sequence. "languages":{ }, // Any languages supported. "channel": { }, // As in channel.settings.js "waitroom":{ }, // As in waitroom.settings.js "auth":{ }, // As in auth.settings.js "requirements":{ }, // As in requirements.settings.js "aliases":{} // If any defined } }

info

Returns combined info for active games and channels.

Call:

http://localhost:8080?q=info 

Return value:

{ "channels": { "ultimatum": { } // See ?q=channels } "games": {  "ultimatum": { } // See ?q=games } }

waitroom

Returns current status of waiting rooms.

Call:

http://localhost:8080?q=waitroom&game=ultimatum 

Select the waiting room of a particular level within the game:

http://localhost:8080?q=waitroom&game=ultimatum&level=level2 

Return value:

{"nPlayers":0} // Players currently waiting.

Enabling Info Query

The Info query is disabled by default. To enable the server configuration (conf/servernode.js) file inside the nodeGame installation folder and add the following line:

servernode.enableInfoQuery = true;

Cyclic Structures

In case of cyclic structures (e.g., a loaded database in game.setup.js) an error will be raised.
