Amazon Provider for OAuth 2.0 Client

This package provides Amazon OAuth 2.0 support for the PHP League's OAuth 2.0 Client.

Installation

composer require michaelkaefer/oauth2-amazon

Usage

$amazonProvider = new \MichaelKaefer\OAuth2\Client\Provider\Amazon([
    'clientId'                => 'yourId',          // The client ID assigned to you by Amazon
    'clientSecret'            => 'yourSecret',      // The client password assigned to you by Amazon
    'redirectUri'             => 'yourRedirectUri'  // The return URL you specified for your app on Amazon
]);

// Get authorization code
if (!isset($_GET['code'])) {
    // Options are optional, defaults to ['profile']
    $options = ['profile', 'postal_code', 'payments:widget', 'payments:shipping_address', 'payments:billing_address'];
    // Get authorization URL
    $authorizationUrl = $amazonProvider->getAuthorizationUrl($options);

    // Get state and store it to the session
    $_SESSION['oauth2state'] = $amazonProvider->getState();

    // Redirect user to authorization URL
    header('Location: ' . $authorizationUrl);
    exit;
// Check for errors
} elseif (empty($_GET['state']) || (isset($_SESSION['oauth2state']) && $_GET['state'] !== $_SESSION['oauth2state'])) {
    if (isset($_SESSION['oauth2state'])) {
        unset($_SESSION['oauth2state']);
    }
    exit('Invalid state');
} else {
    // Get access token
    try {
        $accessToken = $amazonProvider->getAccessToken(
            'authorization_code',
            [
                'code' => $_GET['code']
            ]
        );
    } catch (\League\OAuth2\Client\Provider\Exception\IdentityProviderException $e) {
        exit($e->getMessage());
    }

    // Get resource owner
    try {
        $resourceOwner = $amazonProvider->getResourceOwner($accessToken);
    } catch (\League\OAuth2\Client\Provider\Exception\IdentityProviderException $e) {
        exit($e->getMessage());
    }
        
    // Now you can store the results to session etc.
    $_SESSION['accessToken'] = $accessToken;
    $_SESSION['resourceOwner'] = $resourceOwner;
    
    var_dump(
        $resourceOwner->getId(),
        $resourceOwner->getName(),
        $resourceOwner->getPostalCode(),
        $resourceOwner->getEmail(),
        $resourceOwner->toArray()
    );
}
