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){

        alert("浏览器不支持localstorage");

        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) {

        refreshToken(token);

    }

    //1天过期 重新登录

    if(time >= parse_time) {

        window.location.href = "login.html";

    }

    return token;

}

function headerSetup(token)

{

    $.ajaxSetup({

        'headers':{

            'Authorization': 'Bearer '+ token,

        }

    });

}

//刷新token

function refreshToken(token)

{

      if(window.localStorage.length==0){

           window.localStorage.clear();

           window.location.href = "login.html";

      }

    $.ajaxSetup({

        'headers': {

            'Authorization': 'Bearer ' + token,

        }

    });

    $.ajax({

        url:"http://ezist.cn/api/authorizations/current",

        type:'post',

        dataType: "json",

        data: {},

        success: function(data) {

            setToken(data);

        },

        error: function (data) {

            console.log("数据请求失败");
