PHP Google 服务帐户授权日历 API

Question

我想从我的网站分享活动并将其添加到我自己的 google 日历中。所以，我不想要 oauth 提示。因为访问我网站的用户也可以将活动添加到我的日历中。

我认为我做对了，但我有这个错误：Client is unauthorized to retrieve access tokens using this method, or client not authorized for any of the scopes requested

因此，我不确定是否需要付费工作区帐户才能执行此操作。如果不是，我不明白我哪里失败了？

这是我的代码：

$client = new Google\Client();

$client->setAuthConfig('./secret.json');
$client->setApplicationName('app name');
$client->addScope(Google\Service\Calendar::CALENDAR_EVENTS);
$client->setSubject('mail@gmail.com');
$client->setAccessType('offline');

$service = new Google\Service\Calendar($client);

$event = new Google\Service\Calendar\Event(array(
    'summary' => 'summary',
    'location' => 'street bla bla',
    'description' => 'first event',
    'start' => array(
        'dateTime' => '2021-11-30T10:00:00.000-05:00',
        'timeZone' => 'Europe/Brussels',
    ),
    'end' => array(
        'dateTime' => '2021-11-30T10:00:00.000-05:00',
        'timeZone' => 'Europe/Brussels',
    )
));

$service->events->insert('calendar_id', $event);

谢谢

问题是您正在尝试将主题或委托设置为普通的 Gmail 电子邮件地址 $client->setSubject('mail@gmail.com');

服务帐户只能与 Google 工作区域帐户一起使用，并且只有在您正确设置对域中用户的委派后才能使用。

很遗憾地告诉您，您将无法使用带有您的 gmail 电子邮件地址的服务帐户。

您可以做的是运行来自示例项目的代码，它使用已安装的应用程序并存储刷新令牌。此代码将是单个用户。您将不得不对其进行一些监控，因为刷新令牌可能会过期，尽管一旦您的项目设置为产品，它就不那么常见了。

require __DIR__ . '/vendor/autoload.php';

if (php_sapi_name() != 'cli') {
    throw new Exception('This application must be run on the command line.');
}

    $client->setAuthConfig('credentials.json');
    $client->setAccessType('offline');
    $client->setPrompt('select_account consent');

    // Load previously authorized token from a file, if it exists.
    // The file token.json stores the user's access and refresh tokens, and is
    // created automatically when the authorization flow completes for the first

    if (file_exists($tokenPath)) {
        $accessToken = json_decode(file_get_contents($tokenPath), true);
        $client->setAccessToken($accessToken);
    }

    // If there is no previous token or it's expired.
    if ($client->isAccessTokenExpired()) {
        // Refresh the token if possible, else fetch a new one.

    return $client;
