js源生写cookie封装

//写cookies
function setCookie(name,value) {
    var Days = 30;
    var exp = new Date();
    exp.setTime(exp.getTime() + Days*24*60*60*1000);
    document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString();
}

//读取cookies
function getCookie(name) {
    var arr,reg=new RegExp("(^| )"+name+"=([^;]*)(;|$)");

    if(arr=document.cookie.match(reg))

        return unescape(arr[2]);
    else
        return null;
}

//删除cookies
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();
}

因为本人之前在yapi要设置一个token所以可以直接获取token

yapi

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

    if(arr=document.cookie.match(reg))

        return unescape(arr[2]);
    else
        return null;
}

if(getCookie("token")){
    context.query.token = getCookie("token")
}




alert(JSON.stringify(context.responseData))
function setCookie(name,value) {
    var Days = 30;
    var exp = new Date();
    exp.setTime(exp.getTime() + Days*24*60*60*1000);
    document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString();
}
if(context.responseData.result.access_token){
    setCookie("token",context.responseData.result.access_token)
}
