ASP.NET MVC -自动注销

Question

在我的应用程序中，我希望在一段时间的不活动之后将用户注销。用户使用他们的Google帐户登录。

在Web.config文件中，我将<sessionState mode="InProc" timeout="10" />放在<system.web>下，但是在10分钟后，用户没有被注销。

我希望自动注销的另一件事是在完成注销之前执行一段代码。此代码只需更新数据库表中的一个字段。我不想使用JavaScript，因为我希望自动注销工作，如果用户导航远离网站。

您需要修改CookieAuthenticationOptions实例，并提供过期的其他详细信息。

从文件中

• SlidingExpiration - SlidingExpiration设置为true，以指示中间件在处理超过过期窗口一半的请求时重新发出新的cookie。
• ExpireTimeSpan --控制cookie从创建点起将保持有效的时间。过期信息在受保护的cookie票证中。因此，即使在浏览器应该清除它之后传递给服务器，过期的cookie也将被忽略。

代码：

app.UseCookieAuthentication(new CookieAuthenticationOptions
{
    // add these lines
    SlidingExpiration = true,
    ExpireTimeSpan = TimeSpan.FromMinutes(10),
    // rest of your code
}
