This library implements JSON-RPC 2.0 for the Guzzle HTTP client. We try to support all commonly used versions of Guzzle including:

It can be installed in whichever way you prefer, but we recommend Composer.

    "require": {
        "graze/guzzle-jsonrpc": "~2.1"


use Graze\GuzzleHttp\JsonRpc\Client;

// Create the client
$client = Client::factory('http://localhost:8000');

// Send a notification
$client->send($client->notification('method', ['key'=>'value']));

// Send a request that expects a response
$client->send($client->request(123, 'method', ['key'=>'value']));

// Send a batch of requests
    $client->request(123, 'method', ['key'=>'value']),
    $client->request(456, 'method', ['key'=>'value']),
    $client->notification('method', ['key'=>'value'])

Throw exception on RPC error

You can throw an exception if you receive an RPC error response by attaching a subscriber to either the client or the request. You probably won't want to do so with batch requests as the exception will only include the first bad response in your batch.

use Graze\GuzzleHttp\JsonRpc\Client;
use Graze\GuzzleHttp\JsonRpc\Exception\RequestException;
use Graze\GuzzleHttp\JsonRpc\Subscriber\ErrorSubscriber;

// Create the client
$client = Client::factory('http://localhost:8000');

// Create a request and attach the error subscriber
$request = $client->request(123, 'method', ['key'=>'value']);
$request->getEmitter()->attach(new ErrorSubscriber());

// Send the request
try {
} catch (RequestException $e) {
