我有一个脚本，可以在本地文件系统上复制对特定 Google Drive 文件夹及其子文件夹所做的更改。脚本几天来一直运行良好，但今天中午，刷新代码停止运行，我找不到任何解释。
这是演示该问题的日志

这是有问题的代码。为了清楚起见，添加了有关第 160 行的注释。
$client->setAccessType($accessType);
$this->GetClientFromDB($clientId // Handles inserttion of new Client information if necessary; returns as much information as we have otherwise

$authHistoryRow['authConfig'] = json_encode($client_json) ;
$authHistoryRow['clientId'] = $clientId ;
$authHistoryRow['clientSecret'] = $clientSecret ;

$authHistoryRow['appName'] = $appName ;
$authHistoryRow['scopes'] = implode(',', $scopes) ;
$authHistoryRow['accessType'] = $accessType ;
if ((! $rowId) || $client->isAccessTokenExpired()) {
$accessToken = null ;
// Refresh the token...
if ($rowId && $client->isAccessTokenExpired() && $refreshToken) {
$authHistoryRow['refreshToken'] = $refreshToken ;
$client->refreshToken($refreshToken) ;
$accessTokenArray = $client->getAccessToken() ;
(line 160 follows)
$accessToken = (array_key_exists('access_token', $accessTokenArray) ? $accessTokenArray['access_token'] : false) ;
$expires = $accessTokenArray['expires_in'] + time() ;
$authHistoryRow['accessToken'] = $accessTokenArray['access_token'] ;

}

printf("Authorization expired at %s\n", date('Y-m-d H:i', $expires)) ;
$authUrl = $client->createAuthUrl();
printf("Open this link in your browser:\n%s\n", $authUrl);

$authCode = trim(fgets(STDIN));

$authCode = urldecode($matches[1]) ;
// Exchange authorization code for an access token.
$accessTokenArray = $client->fetchAccessTokenWithAuthCode($authCode);
//$output = print_r($accessToken, true) ;

}
$accessExpiresEpoch = time() + $accessTokenArray['expires_in'] ;
当然，这段代码显然可以在这个刷新区域中得到改进（欢迎提出建议！），但无论如何，服务似乎（？）没有刷新令牌，我想了解为什么。如何找出在执行refreshToken()操作后$client->getAccessToken()返回null的原因？我可以执行哪些测试来确保刷新令牌（）操作确实有效，或者如果没有，为什么不呢？
一个选择可能是获得一组新的代币 - 我可以轻松地采取这些步骤，并且有一定成功的把握。但更重要的是为什么在我这样做之前它不起作用。我们不希望每隔几天对应该运行的流程进行手动干预。
如果您的应用程序正在测试，刷新令牌将在 7 天后过期。
