获取了当天总计1903条签到数据，总鸡腿数量为9425，平均值为4.952706253。
以收集到的数据来说，略亏一丢丢。直接+5是最稳妥、长期收益最高的。

作案工具如下，复制到浏览器控制台中使用：

function sleep(ms) {
  return new Promise(resolve => setTimeout(resolve, ms));
}

async function fetchData(page) {
  const url = `https://www.nodeseek.com/api/attendance/board?page=${page}`;
  const response = await fetch(url);
  if (response.ok) {
    return response.json();
  } else {
    return null;
  }
}

    item['id'], item['member_id'], item['day_id'], item['gain'], item['created_at'], item['member_name']
  ]);
  const csvContent = [header, ...rows].map(e => e.join(",")).join("\n");
  return csvContent;

  document.body.removeChild(link);

    console.log(data);
