ZK友好代数哈希函数安全倡议

1.在router.beforeEach()路由首首位加上以下代码

	 /**
	 * 判断锁屏
	 */
	 //登录的时候存的md5加密的密码
  let oldPasswordld = localStorage.getItem("lockPassword");
  //锁屏页面的md5加密密码
  let newlockPassword = localStorage.getItem("newlockPassword");
  console.log(oldPasswordld,newlockPassword)
	if (newlockPassword !== oldPasswordld && to.path !== '/screen') {
    next('/screen')
	}

2.书写锁屏页面和相关路由

下面代码为screen/index.js 为锁屏的页面 首先进入这个页面 默认执行一次 unlock方法里面的localStorage.setItem(“newlockPassword”, md5(this.userForm.newPw));

把解锁的密码存到本都对象存储里面，这样路由就好做处理。
