在PHP應用中簡化OAuth2.0身份驗證集成：OAuth 2.0 Client

這個包能夠讓你以很簡單的方式在在PHP應用中集成OAuth2.0身份驗證。
用法

驗證代碼流程

$provider = new League\OAuth2\Client\Provider\<ProviderName>(array(
    'clientId'  =>  'XXXXXXXX',
    'clientSecret'  =>  'XXXXXXXX',
    'redirectUri'   =>  'https://your-registered-redirect-uri/',
    'scopes' => array('email', '...', '...'),
));

if ( ! isset($_GET['code'])) {

// If we don't have an authorization code then get one
header('Location: '.$provider->getAuthorizationUrl());
exit;


} else {

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

// If you are using Eventbrite you will need to add the grant_type parameter (see below)
$token = $provider->getAccessToken('authorization_code', [
    'code' => $_GET['code'],
    'grant_type' => 'authorization_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
    $userDetails = $provider->getUserDetails($token);

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

} catch (Exception $e) {

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

// Use this to interact with an API on the users behalf
echo $token->accessToken;

// Use this to get a new access token if the old one expires
echo $token->refreshToken;

// Number of seconds until the access token will expire, and need refreshing
echo $token->expires;

}</pre> 
Refreshing a Token

$provider = new League\OAuth2\Client\Provider\<ProviderName>(array(
    'clientId'  =>  'XXXXXXXX',
    'clientSecret'  =>  'XXXXXXXX',
    'redirectUri'   =>  'https://your-registered-redirect-uri/'
));

$grant = new \League\OAuth2\Client\Grant\RefreshToken();
$token = $provider->getAccessToken($grant, ['refresh_token' => $refreshToken]);</pre>
