如何在注销时清除会话

发布于 2024-07-10 15:03:41 字数 159 浏览 8 评论 0原文

当用户单击注销时,我将用户重定向到登录页面,但我不认为它会清除任何应用程序或会话,因为当用户重新登录时,所有数据都会保留。

当前登录页面有一个登录控件,并且后面的代码该页面仅连接登录验证。

有人可以指导我阅读有关处理 ASP.NET 网站登录和注销的优秀教程或文章吗?

I redirect the user to the login page when user click log out however I don't think it clears any application or session because all the data persisted when the user logs back in.

Currently the login page has a login control and the code behind on the page is only wired up the login Authenticate.

Can someone direct me to a good tutorial or article about handling log in and out of ASP.NET web sites?

我希望 Session.Abandon()

Session.Clear() 不会导致 End 触发,并且来自客户端的进一步请求不会引发 Session Start 事件。

I would prefer Session.Abandon()

Session.Clear() will not cause End to fire and further requests from the client will not raise the Session Start event.

Session.Abandon() 销毁会话并触发 Session_OnEnd 事件。

Session.Clear() 只是从对象中删除所有值(内容)。 具有相同密钥的会话仍然活动

因此,如果您使用 Session.Abandon(),您将丢失该特定会话,并且用户将获得一个新的会话密钥。 例如,当用户注销时,您可以使用它。

如果您希望用户保留在同一会话中(例如,如果您不希望他重新登录)并重置其所有会话特定数据,请使用 Session.Clear() 。

Session.Abandon() destroys the session and the Session_OnEnd event is triggered.

Session.Clear() just removes all values (content) from the Object. The session with the same key is still alive.

So, if you use Session.Abandon(), you lose that specific session and the user will get a new session key. You could use it for example when the user logs out.

Use Session.Clear(), if you want that the user remaining in the same session (if you don't want him to relogin for example) and reset all his session specific data.

.NET core 的清除会话的方式略有不同。 没有 Abandon() 函数。

ASP.NET Core 1.0 或更高版本

//Removes all entries from the current session, if any. The session cookie is not removed.
HttpContext.Session.Clear()

在此处查看 api 参考

.NET Framework 4.5 或更高版本

//Removes all keys and values from the session-state collection.
HttpContext.Current.Session.Clear(); 

//Cancels the current session.
HttpContext.Current.Session.Abandon();

在此处查看 api 参考

The way of clearing the session is a little different for .NET core. There is no Abandon() function.

ASP.NET Core 1.0 or later

//Removes all entries from the current session, if any. The session cookie is not removed.
HttpContext.Session.Clear()

See api Reference here

.NET Framework 4.5 or later

//Removes all keys and values from the session-state collection.
HttpContext.Current.Session.Clear(); 

//Cancels the current session.
HttpContext.Current.Session.Abandon();

See api Reference here

session.abandon() 不会从浏览器中删除 sessionID cookie。 因此,此后的任何新请求都将采用相同的会话 ID。
因此,使用 Response.Cookies.Add(new HttpCookie("ASP.NET_SessionId", "")); 在 session.abandon() 之后。

session.abandon() will not remove the sessionID cookie from the browser. Therefore any new requests after this will take the same session ID.
Hence, use Response.Cookies.Add(new HttpCookie("ASP.NET_SessionId", "")); after session.abandon().

对于.Net核心

[HttpPost]
    public IActionResult Logout()
    {
        try
        {
            CookieOptions option = new CookieOptions();
            if (Request.Cookies[AllSessionKeys.AuthenticationToken] != null)
            {
                option.Expires = DateTime.Now.AddDays(-1);
                Response.Cookies.Append(AllSessionKeys.AuthenticationToken, "", option);
            }

            HttpContext.Session.Clear();
            return RedirectToAction("Login", "Portal");
        }
        catch (Exception)
        {
            throw;
        }
    }

for .Net core

[HttpPost]
    public IActionResult Logout()
    {
        try
        {
            CookieOptions option = new CookieOptions();
            if (Request.Cookies[AllSessionKeys.AuthenticationToken] != null)
            {
                option.Expires = DateTime.Now.AddDays(-1);
                Response.Cookies.Append(AllSessionKeys.AuthenticationToken, "", option);
            }

            HttpContext.Session.Clear();
            return RedirectToAction("Login", "Portal");
        }
        catch (Exception)
        {
            throw;
        }
    }
眉目亦如画i 2024-07-17 15:03:42

会话.Clear();

Session.Clear();

转到项目中的文件 Global.asax.cs 并添加以下代码。

    protected void Application_BeginRequest()
    {
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        Response.Cache.SetExpires(DateTime.Now.AddHours(-1));
        Response.Cache.SetNoStore();
    }

它对我有用..!

        Response.Cache.SetNoStore();
    }

It worked for me..!

我使用以下方法清除会话并清除 aspnet_sessionID

HttpContext.Current.Session.Clear();
HttpContext.Current.Session.Abandon();
HttpContext.Current.Response.Cookies.Add(new HttpCookie("ASP.NET_SessionId", ""));

I use following to clear session and clear aspnet_sessionID:

HttpContext.Current.Session.Clear();
HttpContext.Current.Session.Abandon();
HttpContext.Current.Response.Cookies.Add(new HttpCookie("ASP.NET_SessionId", ""));
