实现“记录用户登录时间和退出时间，同时记录用户IP，并且要记录用户IP对应的省和城市地址”

想实现“记录用户登录时间和退出时间，同时记录用户IP，并且要记录用户IP对应的省和城市地址”

用Session_Start和Session_End，实现是最初的想法，结果不理想。

主要是时间不准确，不能将TimeOut时间设得太短了。

关键过程：

新建一aspx页面-spyWin.aspx

 protected void Page_Load(object sender, EventArgs e)
    {
        
        Common.LogOut();

        string script = "<script type='text/javascript' " +
                "language='javascript'> " +
                " function check_opener() { " +

                " parent.opener=''; " +
                " parent.close(); " +

                "} " +
                " onload = function() { " +
                " self.blur(); " +
                " setTimeout('check_opener()',0); " +
                " } " +
                " </script>";
        this.Controls.Add(new LiteralControl(script));

    }

//以上是spyWin.aspx的代码

//以下是Common类的代码
 public static void LogLogin(string address)
    {
        
        MyBusiness.DbModel.LogForSale lfs = new LogForSale();
        lfs.LoginTime = DateTime.Now;
        lfs.UserName = Credential.Name;

        if (address.Length > 1)
        {
         lfs.IP=   address.Split(',')[0];
         lfs.Province = address.Split(',')[2];
         lfs.City = address.Split(',')[3];
        }
        
        
        lfs.Save();

        System.Web.HttpContext.Current.Session["LFS"] = lfs;
    }
    
    
    public static void LogOut()
    {
        if (Credential != null)
        {
            MyBusiness.DbModel.LogForSale lfs = System.Web.HttpContext.Current.Session["LFS"] as MyBusiness.DbModel.LogForSale;
            if (lfs!=null&&lfs.ID > 0)
            {
                lfs.LogoutTime = DateTime.Now;
                lfs.Save();
            }
        }
    }

完成上述关键（非全部） 步骤后，在真正的网站母版页里加上

    <script language="javascript">
function launch_spyWin() 
{
    spyWin = open('spyWin.aspx','spyWin',
       'width=100,height=100,left=2000,top=0,status=0');
    spyWin.blur();
}
onunload = launch_spyWin;



    </script>

为了记录登录时间等，需要在登录的事件里添加

 Common.LogLogin(TextBoxLog.Text); 

 登录页面加上：

    <asp:TextBox runat="server" ID="TextBoxLog" CssClass="TextBoxLog Element-Hide"></asp:TextBox>
    </form>
</body>
<%--//2010-4-8 LogForSale 起--%>

<script type="text/javascript" src="http://fw.qq.com/ipaddress" charset="gb2312"></script>

<script type="text/javascript"> 
 
$('.TextBoxLog').val((IPData.join(',')));

</script>
