README

This is no longer supported, please consider forking this repository to make any desired changes.

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

• GuzzleHTTP 6 on master branch, ^3.0 releases
• GuzzleHTTP 5 on guzzle-5 branch, ^2.1 releases
• GuzzleHTTP 4 on guzzle-4 branch, 2.0.* releases
• Guzzle 3 on guzzle-3 branch, ^1.0 releases

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

        "graze/guzzle-jsonrpc": "~3.0"

}

Documentation

<?php
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->sendAll([
    $client->request(123, 'method', ['key'=>'value']),
    $client->request(456, 'method', ['key'=>'value']),
    $client->notification('method', ['key'=>'value'])
]);

Async requests

Asynchronous requests are supported by making use of the Guzzle Promises library; an implementation of Promises/A+.

<?php
use Graze\GuzzleHttp\JsonRpc\Client;

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

// Send an async notification
$promise = $client->sendAsync($client->notification('method', ['key'=>'value']));
$promise->then(function () {
    // Do something
});

// Send an async request that expects a response
$promise = $client->sendAsync($client->request(123, 'method', ['key'=>'value']));
$promise->then(function ($response) {
    // Do something with the response
});

// Send a batch of requests
$client->sendAllAsync([
    $client->request(123, 'method', ['key'=>'value']),
    $client->request(456, 'method', ['key'=>'value']),
    $client->notification('method', ['key'=>'value'])
])->then(function ($responses) {
    // Do something with the list of responses
});

Throw exception on RPC error

You can throw an exception if you receive an RPC error response by adding the option [rpc_error => true] in the client constructor.

<?php
use Graze\GuzzleHttp\JsonRpc\Client;
use Graze\GuzzleHttp\JsonRpc\Exception\RequestException;

// Create the client with the `rpc_error`
$client = Client::factory('http://localhost:8000', ['rpc_error'=>true]);

// Create a request
$request = $client->request(123, 'method', ['key'=>'value']);

// Send the request
try {
    $client->send($request);
} catch (RequestException $e) {
    die($e->getResponse()->getRpcErrorMessage());
}
