具体在这里

if($client->isAccessTokenExpired()) {
  echo 'Access Token Expired'; // Debug
  $client->authenticate;
  $newAccessToken = json_decode($client->getAccessToken());
  $client->refreshToken($newAccessToken->refresh_token);
}

我的令牌过期后，我无法注销或访问任何网页，因为他们需要有效令牌。

我也无法登录，因为它也需要它！

或者，我可以禁用它吗？

修改

我很抱歉，我很累，并且假设每个人都知道我在说什么。问题是，当访问令牌到期时，我可以取消设置$ _SESSION ['access_token']并强制重新启动在（主要问题）或有一种方式只是刷新/禁用令牌/过期，所以它不会妨碍用户的任何正在进行的进程。

我建议您阅读有关OAuth的基本指南，这样您就可以获得一般性的想法。

基本上，服务器和客户端会通过一系列步骤来证明他们是他们所说的人。完成此操作后，服务器将发出短暂的access_token和refresh_token。

然后，您可以在所有Api请求中使用此access_token。但是这个access_token的生命周期有限。到期后，您必须将refresh_token提供给服务器，然后它会发出另一个access_token

要使用Google Api PHP库执行此操作，请使用此代码

//$client is the GApi Client
if($client->isAccessTokenExpired()) {
    echo 'Access Token Expired'; // Debug
    $client->refreshToken('your_refresh_token');
}
