我在google-api-client-php库中使用了user-example.php，它正在抛出错误
Fatal error: Uncaught exception 'Google_Auth_Exception' with message 'Could not json decode the token' in /Applications/XAMPP/xamppfiles/htdocs/Calendar/google-api-php-client/src/Google/Auth/OAuth2.php:174 Stack trace: #0 /Applications/XAMPP/xamppfiles/htdocs/Calendar/google-api-php-client/src/Google/Client.php(196): Google_Auth_OAuth2->setAccessToken('[]') #1 /Applications/XAMPP/xamppfiles/htdocs/calendar/google-api-php-client/examples/user-example.php(80): Google_Client->setAccessToken('[]') #2 {main} thrown in /Applications/XAMPP/xamppfiles/htdocs/Calendar/google-api-php-client/src/Google/Auth/OAuth2.php on line 174

任何人都可以解释为什么我可能会收到此错误？我确定我的所有访问权限都已正确设置。我在自己的代码中遇到了问题，但我似乎无法让Google自己的代码工作。
答案 0 :(得分：9)
我遇到了同样的问题。似乎最新的Google API PHP库期望在setAccessToken方法中使用json编码的令牌。所以我作为一个解决方案所做的就是将令牌编码为json。
// $token could be retrieved from your SESSION cookie or from your DB.
$token = array(
'access_token' => 'XXXXXXX',
'refresh_token' => 'XXXXXXX');
$json_token = json_encode($token);
$client->setAccessToken($json_token);
希望这有帮助。

您可以复制粘贴$_SESSION['access_token']吗？
试试这个：
http://php.net/manual/es/function.json-last-error.php
在您的代码中，更改：
json_decode($_SESSION['access_token']);
if (isset($_SESSION['access_token']) && $_SESSION['access_token'] && !json_last_error()) {
$client->setAccessToken($_SESSION['access_token']);
} else {
$authUrl = $client->createAuthUrl();
}
