有人能解释一下这两种语法之间的区别吗？为什么第一种语法不起作用？

这给我一个401错误：

const handleSubmit = () => {
axios.put(`url`, {
    headers: {
      Authorization: `Token ${token}`,
      "Content-Type": "application/json",
    },
    data: data,
  })
  .then(function (response) {
    console.log(JSON.stringify(response.data));
  })

 };

当这完美的工作：

var config = {
method: "put",
maxBodyLength: Infinity,
url: "url",
headers: {
  Authorization: `Token ${token}`,
  "Content-Type": "application/json",
},
data: data,
};

const handleSubmit = () => {
axios(config)
  .then(function (response) {
    console.log(JSON.stringify(response.data));
  })
};
