# Spotify Provider for OAuth 2.0 Client

This package provides Spotify OAuth 2.0 support for the PHP League's [OAuth 2.0 Client](https://github.com/thephpleague/oauth2-client).

## Installation

You can install this package using Composer:

```
composer require kerox/oauth2-spotify
```

You will then need to:
* run ``composer install`` to get these dependencies added to your vendor directory
* add the autoloader to your application with this line: ``require('vendor/autoload.php');``

## Usage

Usage is the same as The League's OAuth client, using `\Kerox\OAuth2\Client\Provider\Spotify` as the provider.

### Authorization Code Flow

```php
$provider = new Kerox\OAuth2\Client\Provider\Spotify([
'clientId' => '{spotify-client-id}',
'clientSecret' => '{spotify-client-secret}',
'redirectUri' => 'https://example.com/callback-url',
]);

if (!isset($_GET['code'])) {
// If we don't have an authorization code then get one
$authUrl = $provider->getAuthorizationUrl([
'scope' => [
Kerox\OAuth2\Client\Provider\SpotifyScope::USER_READ_EMAIL->value,
]
]);

$_SESSION['oauth2state'] = $provider->getState();

header('Location: ' . $authUrl);
exit;

// Check given state against previously stored one to mitigate CSRF attack
} elseif (empty($_GET['state']) || ($_GET['state'] !== $_SESSION['oauth2state'])) {

unset($_SESSION['oauth2state']);
echo 'Invalid state.';
exit;

}

// Try to get an access token (using the authorization code grant)
$token = $provider->getAccessToken('authorization_code', [
'code' => $_GET['code']
]);

// Optional: Now you have a token you can look up a users profile data
try {

// We got an access token, let's now get the user's details
/** @var \Kerox\OAuth2\Client\Provider\SpotifyResourceOwner $user */
$user = $provider->getResourceOwner($token);

// Use these details to create a new profile
printf('Hello %s!', $user->getDisplayName());

echo '

';

var_dump($user);
echo '
';

} catch (Exception $e) {

// Failed to get user details
exit('Damned...');
}

echo '

';

// Use this to interact with an API on the users behalf
var_dump($token->getRefreshToken());
# string(217) "CAADAppfn3msBAI7tZBLWg...

// The time (in epoch time) when an access token will expire
var_dump($token->getExpires());
# int(1436825866)
echo '

';
```
