使用 Google API，我希望檢索我從 Youtube 帳戶訂閱的頻道列表。為此，我使用了以下 PHP 庫：https://packagist.org/packages/league/oauth2-client。應用所有必要的信息后，我收到以下錯誤：致命錯誤：未捕獲的 UnexpectedValueException：從授權服務器收到的響應無效。預期的 JSON ....這是我的代碼：<?phprequire 'vendor/autoload.php';$provider = new \League\OAuth2\Client\Provider\GenericProvider([    'clientId'                => 'my_oauth_client_id',    // The client ID assigned to you by the provider    'clientSecret'            => 'my_oauth_client_secret',   // The client password assigned to you by the provider    'redirectUri'             => 'http://localhost/oauthytb/index.php',    'urlAuthorize'            => 'https://accounts.google.com/o/oauth2/v2/auth',    'urlAccessToken'          => 'https://oauth2.googleapis.com/token',    'urlResourceOwnerDetails' => 'https://www.googleapis.com/auth/youtube.readonly']);// If we don't have an authorization code then get oneif (!isset($_GET['code'])) {    $options = [        'scope' => ['https://www.googleapis.com/auth/youtube.readonly']    ];        // Fetch the authorization URL from the provider; this returns the    // urlAuthorize option and generates and applies any necessary parameters    // (e.g. state).    $authorizationUrl = $provider->getAuthorizationUrl($options);    // Get the state generated for you and store it to the session.    $_SESSION['oauth2state'] = $provider->getState();    // Redirect the user to the authorization URL.    header('Location: ' . $authorizationUrl);    exit;// Check given state against previously stored one to mitigate CSRF attack} elseif (empty($_GET['state']) || (isset($_SESSION['oauth2state']) && $_GET['state'] !== $_SESSION['oauth2state'])) {    if (isset($_SESSION['oauth2state'])) {        unset($_SESSION['oauth2state']);    }        exit('Invalid state');}
