Generic RESTful PHP client

A generic RESTful PHP client for interacting with JSON APIs.

Usage

To use this client you just need to import ApiClient and initialize it with an API Key, Secret and URL endpoint

$api = new RestfulClient\ApiClient('#your_api_key', '#your_api_secret', '#your_api_endpoint');

Now that you have a RESTful API object you can start sending requests.

Request Authentication

All requests include the following headers by default:

• 'X-Authentication-Key' - The API Key provided when creating the ApiClient object.
• 'X-Authentication-Nonce' - An incremental number to prevent request replays. By default this is the current epoch time in milliseconds.
• 'X-Authentication-Signature' - A SHA512 HMAC signature of the nonce, signed using the API Secret provided when creating the ApiClient object.

Making a request

The framework supports GET, PUT, POST and DELETE requests:

$api->get('/books/');
$api->post('/books/', array('title' => 'Twilight', 'author' => 'Stephenie Meyer'));
$api->put('/book/Twilight/', array('release_date' => '06/09/2006'));
$api->delete('/book/Twilight/');

Verifying Requests

Two helpers are built in to verify the success of requests made. ok() checks for a 20x status code and returns a boolean, errors() returns the body content as an associative array if the status code is not 20x:

$req = $api->get('/books/');

if( $req->ok() ) {
    echo 'Success!';
} else {
    echo $req->errors();
}

Extending the client

The client can be extended to be more application specific, e.g. $api->create_book('Twilight', 'Stephenie Meyer');:

class YourAPI extends \RestfulClient\ApiClient 
{
    public function __construct($api_key, $api_secret)
    {
        $api_url = 'https://api.yourdomain.com'
        parent::__construct($api_key, $api_secret, $api_url);
    }

    public function create_book($title, $author)
    {
        $data = array(
            'title' => $title,
            'author' => $author,
        );

        return $this->post('/books/', $data);
    }
}
