JSON-RPC client and server libraries

This library contains a PHP implementation of JSON-RPC version 2, both client and server.


Download the contents of the lib folder to your project. Then simply include the library:

include "lib/Server.php";
$server = new Lightbulb\Json\Rpc2\Server;

With server, you just define define methods in a couple of different ways:

$server = new Lightbulb\Json\Rpc2\Server;

// Class based where all the methods in myClass are exposed as user.method
$server->user = new MyClass;

// Anything that is "callable", either built in PHP functions or your own
$server->upper     = 'strtoupper';
$server->userClean = 'userClean';

// Anonymous functions work too
$server->firstTwo = function($str) { return substr($str,0,2); };

// Force a namespace to map to an object method
$server->{'mytesthandler.myfunc'} = array($myObject, 'myMethod');

// Static method calls work
$server->myStaticHandler = 'MyStaticClass::theStaticFunction';

The methods, which are given to the server, can be then called via numbered or named parameters (see json-rpc specification here: )

The server class respects binding of event methods:

// Bind events
$server->onBeforeCall[] = function($server) {};
$server->onBeforeCall[] = function($server) {};
$server->onSuccess[]    = function($server) {};
$server->onError[]      = function($server) {};

// Another way of in-binding the events; it does *not* remove the last one
$server->onError = function($server) {};

For detailed usage see comments with the server and clients class. For detailed tests see tests folder.

There is an example implementation of the presenter within "example" folder, which can be used for Nette Framework (TM)

Both server and client supports for "dots magic". That is, every method called using the RPC classes can contain dots. The dots then separates individual objects. ie:

$client = new Lightbulb\Json\Rpc2\Client('http://endpoint');

will actually result in following json call:

{... method: "first.second.third" ...}

Test suite

Within "test-suite" folder you can find implementation of the generic test-suite module for Nette Framework projects. With that, you can simply semi-generate the test suite, which you can use both for reference & mainly testing of all your methods.

If you want to use test-suite or examples, you need to use Nette Framework.

Known bugs

Due to the nature of PHP, when you use optional argument of method like this:

$server->user->store($object = null)

you cannot then use "exact resolution operator" === . Hence, only following is applicable:

if($object != null) // note the "!="

This applies only to NULL variables.
