Google+登录:如何注销-使用(gapi.auth.signOut) [英] Google+ Login: How to logout - using (gapi.auth.signOut)
问题描述
在如何使用您的Google+帐户登录的网站上创建退出功能方面,我需要一些帮助.
I need a little help on how to create a sign out function from a website where you have sign in using your Google+ account.
文档指出您应该使用gapi.auth.signOut函数
The documentation states you should use the gapi.auth.signOut function
https://developers.google.com/+/web/signin/退出
但是作为javascript的新手,我似乎没有任何运气.
But being a newbie to javascript I don't seem to have any luck.
这是我的代码-退出功能在底部.我在做什么错了?
This is my code - the sign out function is the part at the bottom. What am I doing wrong?
<script>
function signinCallback(authResult) {
if (authResult['status']['signed_in']) {
// Update the app to reflect a signed in user
// Hide the sign-in button now that the user is authorized, for example:
document.getElementById('signinButton').setAttribute('style','display: none ');
document.getElementById('callback').setAttribute('style','height: 100px;background-color: red ');
var mydiv = document.getElementById("callback");
var aTag = document.createElement('a');
aTag.innerHTML = "Sign out";
aTag.id= "signout";
mydiv.appendChild(aTag);
/*function checkid(){
document.getElementById('signout')
}*/
} else {
// Update the app to reflect a signed out user
// Possible error values:
// "user_signed_out" - User is signed-out
// "access_denied" - User denied access to your app
// "immediate_failed" - Could not automatically log in the user
console.log('Sign-in state: ' + authResult['error']);
}
}
document.addEventListener('DOMContentLoaded', function () {
document.getElementById("signout").addEventListener('click', function(){
gapi.auth.signOut();
});
</script>
推荐答案
如果希望要求您的用户重新输入凭据,则需要撤消对该应用程序的用户身份验证.在我的应用程序中,我像下面的代码片段一样进行了操作.您可能会发现此答案很有用.
If you want your user to be asked to reenter credentials, you will need to revoke the user's authentication to your application. In my application i did it like the snippet below. You might find this answer useful.
var token = gapi.auth.getToken();
if (token) {
var accessToken = gapi.auth.getToken().access_token;
if (accessToken) {
// make http get request towards: 'https://accounts.google.com/o/oauth2/revoke?token=' + accessToken
// In angular you can do it like this:
// $http({
// method: 'GET',
// url: 'https://accounts.google.com/o/oauth2/revoke?token=' + accessToken
// });
}
}
gapi.auth.setToken(null);
gapi.auth.signOut();
