javascript - 无法退出 Google OAuth2

我无法使用 Google signOut() 退出我已登录的 oAuth session 。

例如，我粘贴了直接从 Google 快速入门网站获取的以下代码... https://developers.google.com/google-apps/calendar/quickstart/js

我已将其保存到网站上的 1.htm 文件中，并尝试驱动 Google API。

当我从我的 API 控制台使用 OAuth 2.0 客户端 ID(未在附加代码中显示)时，我能够登录并查看我的日历事件。但是，当单击“注销”按钮时，我不会注销。

enter image description here

点击注销后，下面的代码肯定会运行...

enter image description here

但是，它并没有让我退出。从控制台运行，我看到它仍然认为我已登录... enter image description here

我正在监听登录我们退出时状态的任何变化... enter image description here

但是 signOut() 的回调永远不会被命中... enter image description here

最后，如果我从开发者控制台尝试整个过程...

  1. 显示 gapi.auth2 表示我已登录
  2. 手动退出命令
  3. 显示 gapi.auth2 说我仍然登录 enter image description here

如何修改此代码以使 signOut() 工作？

最佳答案

尝试使用 revoking token HTTP/REST 方法:

To programmatically revoke a token, your application makes a request to https://accounts.google.com/o/oauth2/revoke and includes the token as a parameter:

curl -H "Content-type:application/x-www-form-urlencoded" \
        https://accounts.google.com/o/oauth2/revoke?token={token}

The token can be an access token or a refresh token. If the token is an access token and it has a corresponding refresh token, the refresh token will also be revoked.
