如何从fetch POST响应中获取特定的嵌套值？

fetch(url, {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
  },
  body: JSON.stringify(data),
})
.then(response => response.json())
.then(data => {
  // 在这里处理响应数据
})
.catch(error => {
  // 处理请求错误
});

{
  "status": "success",
  "data": {
    "user": {
      "name": "John",
      "age": 25
    }
  }
}

.then(data => {
  const userName = data.data.user.name;
  const userAge = data['data']['user']['age'];
  console.log(userName); // 输出：John
  console.log(userAge); // 输出：25
})

{
  "status": "success",
  "data": {
    "user": {
      "name": "John",
      "age": 25,
      "hobbies": ["reading", "coding"]
    }
  }
}

.then(data => {
  const userHobbies = data.data.user.hobbies;
  console.log(userHobbies); // 输出：["reading", "coding"]
})
