vue缓存过期问题

//存入缓存
setLocalstorage: function (name, item) {
localStorage.setItem(name, “{“time”:” + (new Date().getTime()) + “,“item”:” + JSON.stringify(item) + “}”);
},
//调用缓存
getLocalstorage: function (name, time) {
time = time || 0; //默认0不过期
var s = localStorage.getItem(name);
var result = false;
if (s) {
s = JSON.parse(s);
//不过期
if (time == 0 || new Date().getTime() < parseInt(s.time) + parseInt(time)) {
result = s.item;
}
}
return result;
},
//移除缓存
removeLocalstorage: function (name) {
localStorage.removeItem(name);
},
