解决cookie存取中文乱码问题

1.向cookie中存入汉字：

Cookie nameCookie=new Cookie("name",name);

改写为：Cookie nameCookie=new Cookie("name",URLEncoder.encode(name,"UTF-8"));//会抛异常

nameCookie.setMaxAge(60*20);

response.addCookie(nameCookie);

2.Js中从cookie中读取：

      <scripttype="text/javascript">

                 function getCookie(name){

                      var arr=document.cookie.match(newRegExp("(^| )"+name+"=([^;]*)(;|$)"));

                      if(arr!=null)

                           return unescape(arr[2]);改写为：return decodeURI(arr[2]) ;

                      return null;

                 }

                 var userName =getCookie("name");

        </script>
