1.assets文件夹 / js文件夹 / 新建cookie.js文件

//获取cookie、
var setCookie = function setCookie(cname, cvalue, exdays) {
var d = new Date();
d.setTime(d.getTime() + (exdays * 24 * 60 * 60 * 1000));
var expires = "expires=" + d.toGMTString();
document.cookie = cname + "=" + cvalue + "; " + expires;
}
var getCookie = function getCookie(cname) {
var name = cname + "=";
var ca = document.cookie.split(';');
for (var i = 0; i < ca.length; i++) {
var c = ca[i].trim();
if (c.indexOf(name) == 0) { return c.substring(name.length, c.length); }
}
return "";
}
//删除cookie
var delCookie= function delCookie (name) {
var exp = new Date();
exp.setTime(exp.getTime() - 1);
var cval = getCookie(name);
if (cval != null)
document.cookie = name + "=" + cval + ";expires=" + exp.toGMTString();
};

export {
getCookie,setCookie,delCookie
}

2.需要用的页面引入

import { setCookie,getCookie,delCookie} from '../../assets/js/cookie.js'

3.使用

setCookie("token",token,7);
var tokens=getCookie("token");
