PHP谷歌API -缺失范围

Question

我使用的是基于Google的日历示例应用程序，它工作得很好。

    $client = new Google_Client();
    $client->setApplicationName("Google Calendar PHP Starter Application");
    $client->setClientId('myclientid.apps.googleusercontent.com');
    $client->setClientSecret('mysecret');
    $client->setRedirectUri('http://localhost/admin/index.php?m=1&e=calendar');
    $client->setDeveloperKey('mykey');
    if (isset($_GET['code'])) {
        $client->authenticate($_GET['code']);
        $_SESSION['token'] = $client->getAccessToken();
        header('Location: http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF']);
    }
    if (isset($_SESSION['token'])) {
        $client->setAccessToken($_SESSION['token']);
    }
    if (!$client->getAccessToken()) {
        $authUrl = $client->createAuthUrl();
        header('Location: ' . $authUrl);
    }

但是我得到:

Error: invalid_request
Missing required parameter: scope

Answer 1

在我设置了developerKey

之后缺少了这一行

$cal = new Google_CalendarService($client);

我猜从客户端获取日历服务的行为设置了作用域。很合理。
