关于cookie的获取设置和修改

新增名为name的cookie和有效时间

setCookie (name, value, expiredays) {
 
    var exdate = new Date();
 
    exdate.setDate(exdate.getDate() + expiredays);
 
    document.cookie = name + "=" + value + ((expiredays == null) ? "" : ";expires=" + exdate.toGMTString());
 
};

获取名为name的cookie的值

getCookie(name) {
	var arr, reg = new RegExp("(^| )" + name + "=([^;]*)(;|$)");
	if (arr = document.cookie.match(reg)){
   		return (arr[2]);
  	}else{
		return false
	}
 }

删除为name的cookie

export function delCookie (name) {
	var exp = new Date();
	exp.setTime(exp.getTime() - 1);
	var cval = getCookie(name);
	if (cval){
	 	document.cookie = name + "=" + cval + ";expires=" + exp.toGMTString();
	}
};

操作完想要达到token失效的效果只需要

location.reload()
