cookie

一、设置cookie

export function setCookie(name, value, expires, path, domain, secure) {
    let cookieText = encodeURIComponent(name) + '=' + encodeURIComponent(value);
    if (expires instanceof Date) {
        cookieText += '; expires=' + expires.toGMTString();
    }
    if (path) {
        cookieText += '; path=' + path;
    }
    if (domain) {
        cookieText += '; domain=' + domain;
    }
    if (secure) {
        cookieText += '; secure';
    }
    document.cookie = cookieText;
}

二、获取cookie

export function getCookie(name) {
    let cookieName = encodeURIComponent(name) + '=';
    let cookieStart = document.cookie.indexOf(cookieName);
    let cookieValue = null;
    if (cookieStart > -1) {
        let cookieEnd = document.cookie.indexOf(';', cookieStart);
        if (cookieEnd === -1) {
            cookieEnd = document.cookie.length;
        }
        cookieValue = decodeURIComponent(document.cookie.substring(cookieStart + cookieName.length, cookieEnd));
    }
    return cookieValue;
}

三、删除cookie

export function deleteCookie(name, path, domain, secure) {
    let cookieText = encodeURIComponent(name) + '=' + '';
    cookieText += '; expires=' + new Date(0).toGMTString();
    if (path) {
        cookieText += '; path=' + path;
    }
    if (domain) {
        cookieText += '; domain=' + domain;
    }
    if (secure) {
        cookieText += '; secure';
    }
    document.cookie = cookieText;
}
