Session与Cookie的简单使用

Session:

登录页面

1 Session["UserName"] = sUsername;

其他页面

1 if (Session["UserName"] == null)
2 {
3     Response.Redirect("Index.aspx");
4 }

说明:看懂用法即可

 

Cookie:

登录页面:

 1                         if(CheckBoxRemeber.Checked)
 2                         {
 3                             Response.Cookies["UserName"].Expires = DateTime.Now.AddDays(7);
 4                             //cookieHelper.SetCookie("UserName", sUsername, 60*24*7);//using com.Utility;
 5                             Response.Cookies["Pwd"].Expires = DateTime.Now.AddDays(7);
 6                             //cookieHelper.SetCookie("Pwd", sPwd, 60*24*7);//using com.Utility;
 7                         }
 8                         Response.Cookies["UserName"].Value = sUsername;
 9                         Response.Cookies["Pwd"].Value = sPwd;
10                         Response.Redirect("UserM.aspx");

其他页面:

1 if (Request.Cookies["UserName"] == null)
2 {
3      Response.Redirect("Index.aspx");
4 }
5 if (cookieHelper.GetCookie("UserName") == null)
6 {
7     Response.Redirect("Index.aspx");
8 }

效果: 如果没有输入用户名和密码的话就会滚回到登录页面.
