JsonRPC - PHP Client and Server

A simple Json-RPC client/server that just works. There is only 2 files.

Features

  • JSON-RPC 2.0 protocol only
  • The server support batch requests and notifications
  • Authentication and IP based client restrictions
  • License: Unlicense http://unlicense.org/

Requirements

  • The only dependency is curl and Reflection classes
  • Works only with PHP >= 5.3

Examples

Server

<?php

require 'JsonRPC/Server.php';

use JsonRPC\Server;

$server = new Server;

// Procedures registration

$server->register('addition', function ($a, $b) {

    return $a + $b;
});

$server->register('random', function ($start, $end) {

    return mt_rand($start, $end);
});

// Return the response to the client
echo $server->execute();

Client

Example with positional parameters:

<?php

require 'JsonRPC/Client.php';

use JsonRPC\Client;

$client = new Client('http://localhost/server.php');
$result = $client->execute('addition', array(3, 5));

var_dump($result);

Example with named arguments:

<?php

require 'JsonRPC/Client.php';

use JsonRPC\Client;

$client = new Client('http://localhost/server.php');
$result = $client->execute('random', array('end' => 10, 'start' => 1));

var_dump($result);

Arguments are called in the right order. If there is an error, the execute() method return NULL.

IP based client restrictions

The server can allow only some IP adresses:

<?php

require 'JsonRPC/Server.php';

use JsonRPC\Server;

$server = new Server;

// IP client restrictions
$server->allowHosts(array('192.168.0.1', '127.0.0.1'));

// Procedures registration

[...]

// Return the response to the client
echo $server->execute();

If the client is blocked, you got a 403 Forbidden HTTP response.

HTTP Basic Authentication

If you use HTTPS, you can allow client by using a username/password.

<?php

require 'JsonRPC/Server.php';

use JsonRPC\Server;

$server = new Server;

// List of users to allow
$server->authentication(array('jsonrpc' => 'toto'));

// Procedures registration

[...]

// Return the response to the client
echo $server->execute();

On the client, set the credentials like that:

<?php

require 'JsonRPC/Client.php';

use JsonRPC\Client;

$client = new Client('http://localhost/server.php');

// Credentials
$client->authentication('jsonrpc', 'toto');

$result = $client->execute('addition', array('a' => 2, 'b' => 2));
