export const getCookie = (name) => {

var arr, reg = new RegExp("(^| )" + name + "=([^;]*)(;|$)");

export const setCookie = (params) => {

var exdate = new Date();

exdate.setDate(exdate.getDate() + expiredays);

//删除cookie

export const delCookie = (params) => {

var exp = new Date();

exp.setTime(exp.getTime() - 1);

var cval = getCookie(name);

if (cval != null)
