Question

在jsp或java中怎么存取cookie值

Answer 1

Cookie []cookies=request.getCookies();
String cookieName="myCookie";
Cookie myCookie=null;
for(int i=0;i<cookies.length;i++) {
if(cookies[i].getName.equals(cookieName)) {
  myCookie=cookie[i];
  break;
 }
}

以上是详细代码，只能这样来获取cookie;

String cookieName="myCookie";
String cookieValue="cookieValue";
Cookie myCookie=new Cookie(cookiename,(Object)cookieValue);
myCookie.setmaxAge(60*60*24);//一天
respose.addCookie(myCookie);

以上是存一个Cookie

Answer 2

cookie是存放在客户端的信息
$.cookie('cookieName', 'cookieValue') //存入值
$.cookie("cookieName")//取出值
