我有一個應用程序使用Google Sign-In for Websites，但只要用戶的會話處於活動狀態就想刷新令牌（例如，他們登錄，閒置2小時但將標籤打開，回來並且不必重新進行認證）。使用Google OAuth 2.0和PHP/JS自動刷新令牌
基於我的研究，它看起來像這個requires setting offline access類型，但我不確定這是否是正確的方向。
如果這是正確的方向 - 我失去了如何將它添加到我現有的代碼。
這裏是我的登錄頁面代碼：
<!doctype html>
<html>
<head>
<!-- jQuery -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<!-- Custom -->

</head>
<body class="loginPage">
<div class="se-pre-con" style="display: none"></div>

<div id="loginBox">
<div class="logo"></div>
<div id="googleSignIn"></div>
<?php if(isset($message)) { ?>
<p class="loginMessage"><?php echo $message ?></p>
<?php } ?>
</div>
</div>
<script>
function onSuccess(googleUser) {
var id_token = googleUser.getAuthResponse().id_token;
$(".se-pre-con").fadeIn("slow");
var authUrl = "auth.php?id_token=" + id_token;
<?php if(isset($_GET['retUrl'])) { ?>
authUrl += "&retUrl=<?php echo urlencode($_GET['retUrl']); ?>";
<?php } ?>
window.location.href = authUrl;
}
function onFailure(error) {
console.log(error);
}
function renderButton() {
gapi.signin2.render('googleSignIn', {
'scope': 'profile email',
'width': 240,
'height': 50,
'longtitle': true,
'theme': 'dark',
'onsuccess': onSuccess,
'onfailure': onFailure
});
}
</script>
<script src="https://apis.google.com/js/platform.js?onload=renderButton" async defer></script>
<script src="<?php echo $pathTo ?>js/particles.js"></script>

@ jwilleke設置離線訪問權限是爲我的用例做的正確事情嗎？ – Matt
