                    accessToken = arr[1];
                    break;

        delete: function (key) {
            let myDate = new Date();

            document.cookie = key + "=''; expires=" + myDate.toGMTString();
        }
    }
};

清除所有cookie

// 清除所有cookie
clearAllCookie () {
    let date=new Date();
    date.setTime(date.getTime()-10000);
    let keys = document.cookie.match(/[^ =;]+(?=\=)/g);
    console.log("需要删除的cookie名字："+keys);
    if (keys) {
        for (let i =  keys.length; i--;)
          document.cookie=keys[i]+"=0; expire="+date.toGMTString()+"; path=/";
    }
}

清除本域名cookie

deleteCookies(){
  let keys = document.cookie.match(/[^ =;]+(?==)/g);
  if (keys) {
    for (var i = keys.length; i--;) {
      document.cookie = keys[i] + '=0;path=/;expires=' + new Date(0).toUTCString() // 清除当前域名下的,例如：m.ratingdog.cn
      document.cookie = keys[i] + '=0;path=/;domain=' + document.domain + ';expires=' + new Date(0).toUTCString() // 清除当前域名下的，例如 .m.ratingdog.cn
      document.cookie = keys[i] + '=0;path=/;domain=ratingdog.cn;expires=' + new Date(0).toUTCString() // 清除一级域名下的或指定的，例如 .ratingdog.cn
    }
  }
