我需要解构出来如下的数据（见附件）
有IP,地址，运营商等，形成一个json进行返回。

响应的结果 ​

js
async function getExternalIP() {
  try {
    const res = await fetch('https://ifconfig.me/all.json');
    const data = await res.json();
    return data.ip_addr;
  } catch (err) {
    console.error('Error fetching IP:', err);
    return null;
  }
}

测试代码：

getExternalIp().then(console.log)
