PHP Google API客户端不一致无法加载正确的凭据(PHP Google API Client Inconsistency not loading proper credentials)

 基本上，我一直在使用PHP Google API客户端库来访问多个用户的gmail收件箱（他们允许通过oAuth2工作流访问）并提取一些数据...... 
 
 观察：客户端仅在10到15分钟后才能正确验证...一旦使用令牌验证用户的gmail收件箱，该用户就可以访问数据。 但是当下一个令牌用于验证另一个用户的gmail收件箱时，PHP google api客户端不会重新加载，而是使用前一个用户（我怀疑它已被缓存/存储在会话中）。 
 
 代码流程： 
 
<?php
$tokenArray = array();
foreach($tokenArray as $token) {
 $googleclient = getGoogleClient($token);
 //$googleclient is stale even after the second iteration of the foreach loop
 $service = new Google_Service_Gmail($googleclient);
 $googleuser = "me";
 //if we change the variable $googleuser to some email address "xyz@gmail.com", we get a "Delegation denied for xyz@gmail.com"
 $userprofile = $service->users->getProfile($googleuser);
 var_dump($userprofile);//same data
}
?>
 
 如果我们将它从循环中取出并在25-30分钟之后进行单独调用（或重新启动apache webserver），则第二个令牌将在客户端库中正确使用。 
 
 是因为Google API PHP客户端库正在缓存对象并重复使用它30分钟或者我错过了什么？ 
 
 我的问题是在处理多个令牌时我应该怎么做才能重新加载客户端？ 
 
 有没有正确的方法/任何其他方式来初始化客户端？ 
 
 你们中的任何人都有PHP Google API客户端库的任何代码片段...我已经在官方文档中检查过但无济于事...... 
 
 谢谢你的帮助 

Basically, I've been using the PHP Google API Client library for accessing gmail inbox of multiple users(who've allowed access through a oAuth2 workflow) and extracting some data...
 
Observations: The Client gets authenticated properly only after 10 to 15 mins of time... Once a token is used to authenticate a user's gmail inbox, data is accessible for that user. but when the next token is used to authenticate another user's gmail inbox, the PHP google api client doesn't reload but uses the previous user(I suspect it's been cached / stored in session).
 
Code flow:
 
<?php
$tokenArray = array();
foreach($tokenArray as $token) {
 $googleclient = getGoogleClient($token);
 //$googleclient is stale even after the second iteration of the foreach loop
 $service = new Google_Service_Gmail($googleclient);
 $googleuser = "me";
 //if we change the variable $googleuser to some email address "xyz@gmail.com", we get a "Delegation denied for xyz@gmail.com"
 $userprofile = $service->users->getProfile($googleuser);
 var_dump($userprofile);//same data
}
?>
 
if we take it out of the loop and make separate calls after 25 - 30 mins(or restart the apache webserver), The second token is used in the client library properly.
 
Is it because the Google API PHP Client Library is caching the object and reusing it for 30 mins or am I missing something?
 
My question is what should I do to reload the client while handling more than one token?
 
Is there a proper way / any other way to initialize the client?
 
Do any of you have any code snippets for PHP Google API Client library... I've checked it in the official docs but to no avail...
 
Thanks for any help
