Java读取Cookie

Java读取COOKIE

首先要通过Cookie[] cookies=request.getCookies();取得所有的COOKIE，然后使用下面的函数取得需要的COOKIE值，没有就返回null

    //取得COOKIE

    public String getCookieValue(Cookie[] cookies, String cookieName) {

        for (int i = 0; i < cookies.length; i++) {

            Cookie cookie = cookies[i];

            if (cookieName.equals(cookie.getName())) {

                return (cookie.getValue());

            }

        }

        return null;

    }
