5.cookie和session和token

cookie原理

token原理

5.1session和cookie的区别

cookie数据存放在客户端的浏览器上，session数据放在服务器上。
单个cookie保存的数据不能超过4K，浏览器都限制一个站点最多保存20个cookie。session没有这种限制。
cookie比session更不安全，别人可以分析存放在本地的cookie并进行cookie欺骗。(可考虑对cookie加密)
session会在一定时间内保存在服务器上。当访问增多时，会比较占用服务器的内容，考虑到减轻服务器负担，可以考虑使用cookie
session存放图片验证码session.setAttribute(CAPTCHA_KEY, verifyCode.toLowerCase());

cookie和token的区别

token存在哪儿都行，客户端可存放在localstorage或者cookie，而服务器端则会存放于数据库(服务器端的session是直接放在内存中的)
cookie 举例：门卫大爷看你的学生证，给你一个编号，以后进行任何操作，都出示编号后服务员去看查你是谁。
token 举例：直接给门卫大爷看自己学生证
对于token而言，服务器不需要去查看你是谁，是无状态的，而cookie则是相对有状态的。
token的可拓展性更强。
token可抵御csrf，因为cookie容易伪造，但是token是不容易伪造的。

5.2 后端接收保存

5.2.1 session和cookie

    @RequestMapping("tes")public String tes(HttpServletRequest req,HttpServletResponse response, HttpSession session) {//1.cookieCookie cookie = new Cookie("mobile", "yu");cookie.setMaxAge(Integer.MAX_VALUE);//设置根目录cookie.setPath("/");//Cookie中 maxAge设置为负值 和0的区别//如果设置为负值，则为浏览器进程Cookie(内存中保存)，关闭浏览器就失效；//如果设置为0，则立即删除该Cookie。//设置Cookie的最大生命周期,否则浏览器关闭后Cookie即失效//设置cookie过期值时间是7天，7*24*60*60单位是秒Cookie cookie1 = new Cookie("mobile1", "10s");cookie1.setMaxAge(10);//将Cookie加到response中response.addCookie(cookie);response.addCookie(cookie1);//2.session//设置session,浏览器关闭后session即失效session.setAttribute("mobile_session","yu1");/* setMaxInactiveInterval(int   i)   i的单位是秒。*如果设置的值为零或负数，则表示会话将永远不会超时。常用于设置当前会话时间。* 不设置关闭浏览器 放弃值*/session.setMaxInactiveInterval(10);final String id = session.getId();System.out.println("sessionid:"+id);return "file/index";}

    @RequestMapping("getse")public String getse(HttpServletRequest req,HttpServletResponse response, HttpSession session) {//获取session值   浏览器关了就没有了   在cookie中看不到String sesionCode = (String) req.getSession().getAttribute("mobile_session");log.info("sesionCode->{}",sesionCode);final Object mobile = session.getAttribute("mobile_session");log.info("mobile ->{}",mobile );//获取Cookie值Cookie[] cookie1 = req.getCookies();for (int i = 0; i < cookie1.length; i++) {Cookie cook = cookie1[i];System.out.println("cook:"+cook);System.out.println("cook.getName():"+cook.getName()); //KSystem.out.println("cook:"+cook.getValue().toString());//Vif(cook.getName().equalsIgnoreCase("mobile")){ //获取键System.out.println("mobile:"+cook.getValue().toString());    //获取值}}return "file/index";}
