服务器端操作Cookie,主要注意会使用以下三个类:

HttpCookie,HttpResponse,HttpRequest

关于HttpCookie:

属性描述例子Domain获取或设置与此Cookie关联的域 Expires获取或设置域的过期时间 HasKeys获取一个值,通过该值指示Cookie是否具有子键 HttpOnly获取或设定一个值,该值指定Cookie是否可通过客户端脚本访问 ItemHttpCookie.Values属性的快捷方式 Name获取或设置Cookie的名称 Path获取或设置要与当前Cookie一起传输的虚拟路径 Secure获取或设定一个值,该值指示是否使用安全套接字段(SSL)传输Cookie Value获取或设置Cookie的值 Values获取单个Cookie对象所包含的键值对的集合cookie.Values["username"]

添加Cookie

public partial class cookie_Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { //创建Cookie HttpCookie cookie = new HttpCookie("User"); //对中文进行编码 cookie["username"] = HttpUtility.UrlEncode("张三"); cookie["password"] = "zhangsan"; //注意:此处不可缺少,此处缺少,则无法成功添加cookie cookie.Expires = DateTime.Now.AddDays(2); //添加Cookie Response.Cookies.Add(cookie); } } 读取Cookie  public partial class cookie_Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { //获取Cookie HttpCookie cookie = Request.Cookies["User"]; //对中文进行解码 //输出: // 张三 // zhangsan Response.Write(HttpUtility.UrlDecode(cookie["username"])+"<br/>"+cookie["password"]); } } 修改Cookie  public partial class cookie_Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Response.Cookies["User"]["username"] = HttpUtility.UrlEncode("李四"); //对中文进行解码 //输出: // 李四 Response.Write(HttpUtility.UrlDecode(Request.Cookies["User"]["username"])); } } 删除Cookie public partial class cookie_Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { //设置Cookie过期,客户端即可自动删除该Cookie Response.Cookies["User"].Expires = DateTime.Now.AddDays(-1); } }
