十二、存token获取token刷新token发送header头

//测试token

//获取token

function setToken(data){

var storage = window.localStorage;

if(!storage){

return false;

}

var token = data.access_token;

storage.setItem("user_token", token);

storage.setItem("user_login_time", new Date().getTime());//保存登录时间

}

function getToken()

{

var storage = window.localStorage;

var current = new Date().getTime();//拿token的时间

var token = storage.user_token;//token的值

var old_time = storage.user_login_time;//登录的时间

var time = (current - old_time) /1000;//时间差

var out_time = 3600;// 超时设置

var parse_time = 24 * 60 * 60;// 刷新设置

//手动清除缓存
   var length = window.localStorage.length;
   if(length==0){ 
window.location.href = "login.html"
}

//超时

if(parse_time > time && time >= out_time) {

//1天过期 重新登录
