即使已正确注册域，Google Calendar API仍会未经授权返回

Question

我正在使用google php客户端库来创建到我的域的Webhook，但是API仍会返回未经授权的内容。

我已成功执行push上有关“注册您的域”的步骤，并且我的域已在API控制台上列出。

根据API和服务>域验证，它在“允许的域”下列出了我的域。

但是它仍然告诉我该域是未经授权的：

库函数

$channel = new Google_Service_Calendar_Channel();
$channel->setId($channelId);
$channel->setType("web_hook");
$channel->setAddress("https://example.com/notifications");
$service->events->watch($calendarId, $channel);

错误消息

{ "error":
  { "errors": [{
    "domain": "global",
    "reason": "push.webhookUrlUnauthorized", 
    "message": "Unauthorized WebHook callback channel: https://example.com/notifications"
    }],
  "code": 401,
  "message": "Unauthorized WebHook callback channel: https://example.com/notifications"
  }
}

Google_Service_Calendar_Channel要求您发送客户端以对其进行身份验证。我个人将使用服务帐户。

function getServiceAccountClient() {
    try {   
        // Create and configure a new client object.        
        $client = new Google_Client();
        $client->useApplicationDefaultCredentials();
        $client->addScope('https://www.googleapis.com/auth/calendar');
        return $client;
    } catch (Exception $e) {
        print "An error occurred: " . $e->getMessage();
    }
}

$client = getServiceAccountClient();
$channel = new Google_Service_Calendar_Channel($client);
$channel->setId($channelId);
$channel->setType("web_hook");
$channel->setAddress("https://example.com/notifications");
$service->events->watch($calendarId, $channel);
