Php ssl错误谷歌驱动器api

我正在使用PHP库检索文件或将其上载到Google drive

include_once ROOT.'/google-api-php-client/vendor/autoload.php';

$client = new Google_Client();

$credentialsFile = ROOT.'/google-api-php-client/service_account.json';
if (!file_exists($credentialsFile)) {
    throw new RuntimeException('Service account credentials Not Found!');
}

$client->setAuthConfig($credentialsFile);
$client->setScopes(Google_Service_Drive::DRIVE);

$service = new Google_Service_Drive($client);

/**
   * Проверка существования папки для документов
   */

$optParams = array(
  'q' => "name='Документы'"
);
$results = $service->files->listFiles($optParams);
if (count($results->getFiles()) == 0) {
exit('Нет папки для документов');
} else {
  foreach ($results->getFiles() as $file) {
$papka_doc = $file->getId();
  }
 }

一切正常，但几天前，出现了一个错误：

Uncaught exception 'GuzzleHttp\\Exception\\RequestException' with message 'cURL error 60: SSL certificate problem: unable to get local issuer certificate (see http://curl.haxx.se/libcurl/c/libcurl-errors.html) 未捕获异常“GuzzleHttp\\exception\\RequestException”，消息为“cURL错误60:SSL证书问题：无法获取本地颁发者证书（请参阅http://curl.haxx.se/libcurl/c/libcurl-errors.html) 有什么问题吗？

试试这个

首先，您应该下载curl.cert文件

curl https://curl.haxx.se/ca/cacert.pem -o /etc/pki/tls/certs/ca-bundle.crt

其次，设置此证书

$client->getHttpClient()->setDefaultOption('verify', '[Certificate File Path]');

Centos默认路径

/etc/pki/tls/certs/ca-bundle.crt

不幸的是，这种方法没有帮助
