Java 处理cookie的方法

一、java创建cookie

方法一：

Response.Cookies["userName"].Value = "patrick";

Response.Cookies["userName"].Expires = DateTime.Now.AddDays(1);

方法二：

HttpCookie aCookie = new HttpCookie("lastVisit");

aCookie.Value = DateTime.Now.ToString();

aCookie.Expires = DateTime.Now.AddDays(1);

Response.Cookies.Add(aCookie);

二、java读取cookie

获取value的值：request.cookie[“name”].value=? 

if(Request.Cookies["userName"] != null)

    Label1.Text = Server.HtmlEncode(Request.Cookies["userName"].Value);

if(Request.Cookies["userName"] != null)

{

    HttpCookie aCookie = Request.Cookies["userName"];

    Label1.Text = Server.HtmlEncode(aCookie.Value);

}

三、java销毁cookie

int counter;

if (Request.Cookies["counter"] == null)

    counter = 0;

else

{

    counter = int.Parse(Request.Cookies["counter"].Value);

}

counter++;

Response.Cookies["counter"].Value = counter.ToString();

Response.Cookies["counter"].Expires = DateTime.Now.AddDays(1);
