以下代码可以正常运行，但会在1小时后过期
$client->setAccessToken($accessToken); //$accessToken contains access_token, refresh_token etc
但如果我这样做，而不是上线
$client->refreshToken('1/c1f43fvAbSSPHTQ8GipjNop6SutKUTvHGOZwDcWop2I'); //dummy code
它给出了这个错误：
Google_AuthException：刷新OAuth2令牌时出错，消息：'{
“错误”：“unauthorized_client”}' Google_OAuth2-＆gt; refreshTokenRequest（）（第288行） .. \谷歌-API-PHP-客户\ SRC \ AUTH \ Google_OAuth2.php）。
可能是什么问题？
同样在批准网址中，设置了approval_prompt = force。
