从JSON API数据中获取字段

{
  "user": {
    "id": 123,
    "name": "John Doe",
    "email": "john.doe@example.com"
  },
  "status": "active"
}

// 假设response是从API获取的JSON字符串
let response = '{"user":{"id":123,"name":"John Doe","email":"john.doe@example.com"},"status":"active"}';

// 解析JSON字符串为JavaScript对象
let data = JSON.parse(response);

// 获取字段
let userId = data.user.id;
let userName = data.user.name;
let userEmail = data.user.email;
let userStatus = data.status;

console.log(userId);    // 输出: 123
console.log(userName);  // 输出: John Doe
console.log(userEmail); // 输出: john.doe@example.com
console.log(userStatus); // 输出: active

try {
  let data = JSON.parse(response);
  // 继续处理数据
} catch (error) {
  console.error("JSON解析错误:", error);
}
