Light PHP wrapper for the OAuth 2.0
How can I use it ?
<?php
require('Client.php');
require('GrantType/IGrantType.php');
require('GrantType/AuthorizationCode.php');
const CLIENT_ID = 'your client id';
const CLIENT_SECRET = 'your client secret';
const REDIRECT_URI = 'http://url/of/this.php';
const AUTHORIZATION_ENDPOINT = 'https://graph.facebook.com/oauth/authorize';
const TOKEN_ENDPOINT = 'https://graph.facebook.com/oauth/access_token';
$client = new OAuth2\Client(CLIENT_ID, CLIENT_SECRET);
if (!isset($_GET['code']))
{
$auth_url = $client->getAuthenticationUrl(AUTHORIZATION_ENDPOINT, REDIRECT_URI);
header('Location: ' . $auth_url);
die('Redirect');
}
else
{
$params = array('code' => $_GET['code'], 'redirect_uri' => REDIRECT_URI);
$response = $client->getAccessToken(TOKEN_ENDPOINT, 'authorization_code', $params);
parse_str($response['result'], $info);
$client->setAccessToken($info['access_token']);
$response = $client->fetch('https://graph.facebook.com/me');
var_dump($response, $response['result']);
}How can I add a new Grant Type ?
Simply write a new class in the namespace OAuth2\GrantType. You can place the class file under GrantType. Here is an example :
<?php
namespace OAuth2\GrantType;
/**
* MyCustomGrantType Grant Type
*/
class MyCustomGrantType implements IGrantType
{
/**
* Defines the Grant Type
*
* @var string Defaults to 'my_custom_grant_type'.
*/
const GRANT_TYPE = 'my_custom_grant_type';
/**
* Adds a specific Handling of the parameters
*
* @return array of Specific parameters to be sent.
* @param mixed $parameters the parameters array (passed by reference)
*/
public function validateParameters(&$parameters)
{
if (!isset($parameters['first_mandatory_parameter']))
{
throw new \Exception('The \'first_mandatory_parameter\' parameter must be defined for the Password grant type');
}
elseif (!isset($parameters['second_mandatory_parameter']))
{
throw new \Exception('The \'seconde_mandatory_parameter\' parameter must be defined for the Password grant type');
}
}
}call the OAuth client getAccessToken with the grantType you defined in the GRANT_TYPE constant, As following :
$response = $client->getAccessToken(TOKEN_ENDPOINT, 'my_custom_grant_type', $params);
