Php 从google日历API获取数据时出错

这是我的密码

use Google_Client;
use Google_Service_Calendar;


class GController extends BaseController
{
   public function client()
   {
        $client = new Google_Client();
        $client->setAuthConfig('/mnt/d/xampp/htdocs/test/client_secret.json');
        $client->addScope(Google_Service_Calendar::CALENDAR);
        $guzzleClient = new \GuzzleHttp\Client(array('curl' =>  array(CURLOPT_SSL_VERIFYPEER => false)));
        $client->setHttpClient($guzzleClient);
        return $client;
    }
    public function index()
    {
        $service = new Google_Service_Calendar($this->client());
        $calendarId = 'primary';
        $results = $service->events->listEvents($calendarId);
        return $results->getItems();
    }
}

我得到了这个错误

"message": [
    "{\n \"error\": {\n  \"errors\": [\n   {\n    \"domain\": \"usageLimits\",\n    \"reason\": \"dailyLimitExceededUnreg\",\n    \"message\": \"Daily Limit for Unauthenticated Use Exceeded.

],

我该怎么做才能解决这个问题。？ 对不起，我是初学者

我的参考是

我觉得解决这个问题很容易。您必须验证您的客户端，并停止匿名使用它

您的错误消息显示：

超出未经验证使用的每日限制继续使用需要注册。

我很清楚为什么会出现此错误。

超出了未经验证使用的每日限制。继续使用需要注册。

这很清楚；）
