浏览器设置，读取，删除cookie方法

// 获取cookie
function getCookie (cookieName) {
  // name=lxw;age=18
  let start = document.cookie.indexOf(cookieName)
  if (start > -1) {
    start = start + cookieName.length + 1;
    let end = document.cookie.indexOf(';', start)
    console.log('', 'color: #40fff2', end);
    end = end > -1 ? end : document.cookie.length
    return unescape(document.cookie.substring(start, end))
  } else {
    return undefined
  }
}

// 设置cookie
function setCookie(cookieName, value, days = 1) {
  const date = new Date()
  date.setTime(date.getTime() + days * 3600 * 24 * 1000)
  document.cookie = `${cookieName}=${escape(value)}; expires=${ date.toGMTString() }; path=/; domian=.kuwo-inc.com`
}

// 删除cookie
const delCookie = (cookie_name) => {
  const exp = new Date();
  exp.setTime(exp.getTime() - 1);
  const val = getCookie(cookie_name);
  if (val != null) {
    document.cookie = cookie_name + '=' + val + ';expires=' + exp.toGMTString() + ';path=/;domain=.kuwo.cn'
  }
};
