会话状态下的asp.net c# [英] asp.net c# in session state

问题描述

我在登录页面(login.aspx.cs)中有如下代码

i have the code in login page(login.aspx.cs) as follows

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class login : System.Web.UI.Page
{
    protected void Button1_Click(object sender, EventArgs e)
    {
        if (txtusername.Text == "ravi" && txtpassword.Text == "reddy")
        {
            Session["PassWord"] = txtpassword.Text;
            Session.Timeout = 1;



            Response.Redirect("checkpassword.aspx");
        }
        else
            Response.Write("wrong details");
    }
}

并且我在password.aspx.cs中有代码

and and i have the code in password.aspx.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class checkpassword : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

        if (Session["PassWord"] == null)
        {

            Response.Redirect("login.aspx");
        }
        else

            lblstatus.Text = Session["PassWord"].ToString();

    }

}

我们想要输出，因为我登录到登录页面后，它在一分钟后刷新了页面，输出显示对不起会话，因此reddy在password.aspx中显示为lable(在浏览器中打开).我需要执行此操作，同时将其重定向到login.aspx页plz help

推荐答案

不要在ASP.net中使用手动身份验证，除非您有一个很好的理由.查看成员资格和角色功能并使用它们.

如果要检查会话到期和自动重定向，则需要一个小的AJAX脚本来调用服务器端脚本，该脚本类似于

Don''t use manual authentication in ASP.net unless you have a really good reason to. Look at the Membership and Roles features and use them.

If you want to check for session expiry and auto-redirect then you need a little AJAX script that calls a server-side script that looks something like

Response.Write(null == Session["PassWord"] ? "expired" : "valid");

...，然后检查结果，并在必要时重定向到登录页面.

... and then checks the result and redirects to a login page if necessary.
