我正在使用谷歌登录我的网站。我已经关注了 这个链接，所以我的代码如下所示。我试图让它在成功登录后重定向到我的索引页面，我该怎么做？
<head>
<meta name="google-signin-client_id" content="My_client_id.apps.googleusercontent.com">
<script src="https://apis.google.com/js/platform.js" async defer></script>
<meta name="google-signin-scope" content="profile email">
</head>
<div class="mx-auto" id="my-signin2"></div>
<script>
function onSuccess(googleUser) {
console.log('Logged in as: ' + googleUser.getBasicProfile().getName());
}
function onFailure(error) {
console.log(error);
}
function renderButton() {
gapi.signin2.render('my-signin2', {
'scope': 'profile email',
'width': 240,
'height': 50,
'longtitle': true,
'theme': 'dark',
'onsuccess': onSuccess,
'onfailure': onFailure
});
}
function onSignIn(googleUser) {
// Useful data for your client-side scripts:
var profile = googleUser.getBasicProfile();
console.log("ID: " + profile.getId()); // Don't send this directly to your server!
console.log('Full Name: ' + profile.getName());
console.log('Given Name: ' + profile.getGivenName());
console.log('Family Name: ' + profile.getFamilyName());
console.log("Image URL: " + profile.getImageUrl());
console.log("Email: " + profile.getEmail());
// The ID token you need to pass to your backend:
var id_token = googleUser.getAuthResponse().id_token;
console.log("ID Token: " + id_token);
}
</script>
<script src="https://apis.google.com/js/platform.js?onload=renderButton" async defer></script> ```
