README

OAuth 2.0 authentication client. It provides multiple grant types, using which you can get authentication data.

Installation

composer require chocofamilyme/oauth2-client

Usage

Grand type "password"

<?php
use Chocofamilyme\OAuth2\Client\Authentication;
use Chocofamilyme\OAuth2\Client\GrandTypes\PasswordGrandType;

$grantType = new PasswordGrandType('client_id', 'username', 'password');
$oauth2 = new Authentication($grantType, 'http://oauth.server.com/auth/token');
$authData = $oauth2->getAuthData();
var_dump($authData);

Grand type "client_credentials"

<?php
use Chocofamilyme\OAuth2\Client\Authentication;
use Chocofamilyme\OAuth2\Client\GrandTypes\ClientCredentialsGrandType;

$grantType = new ClientCredentialsGrandType('client_id', 'client_secret');
$oauth2 = new Authentication($grantType, 'http://oauth.server.com/auth/token');
$authData = $oauth2->getAuthData();
var_dump($authData);

Extending

• You can also extend this library with your grant types, see GrantTypeInterface.
• You can also use your own http client, it just has to implement HttpClientInterface
• If your OAuth 2.0 server gives the response not in the format this library can understand, just write your own response class which has to implement ResponseInterface

Every custom module can then be used in the constructor of the Authentication class

new \Chocofamilyme\OAuth2\Client\Authentication(GrantTypeInterface $grantType, string $authTokenUrl, HttpClientInterface $httpClient = null, ResponseInterface $responseInterface = null)
