Javascript axios 不发送标头，发布请求失败，得到 401

我一直在使用axios从私有API获取一些数据，但现在从一个特定端点获取数据时遇到了问题.

有趣的是，使用内置的fetch API，我收到了200个响应，但与axios相同的请求不断返回401错误.知道有什么问题吗？

此代码适用于:

const upVoteCommentTwo = async () => {
  console.log(localStorage.getItem("access_token"));
  try {
    const response = await fetch(
      `https://exammple.com/comments/${commentId}/vote/up`,
      {
        method: "POST",
        headers: {
          "X-API-KEY": "XXX",
          "Authorization": localStorage.getItem("access_token"),
        },
      }
    );

    console.log(await response.status);
  } catch (err) {
    console.log(err);
  }
};

但这不起作用:

const upVoteCommentOne = async () => {
  console.log(localStorage.getItem("access_token"));
  try {
    const response = await axios.post(
      `https://example.com/comments/${commentId}/vote/up/`,
      {
        headers: {
          "Content-Type": "application/json",
          "X-API-KEY": "XXX",
          "Authorization": localStorage.getItem("access_token"),
        },
      }
    );

    console.log(response.status);
  } catch (err) {
    console.log(err);
  }
};
