动态展开json中的所有列表和记录

function flattenJSON(jsonData) {
  let result = {};

  function flatten(obj, prefix = '') {
    for (let key in obj) {
      if (obj.hasOwnProperty(key)) {
        let newKey = prefix ? `${prefix}.${key}` : key;
        if (Array.isArray(obj[key])) {
          obj[key].forEach((item, index) => {
            flatten(item, `${newKey}[${index}]`);
          });
        } else if (typeof obj[key] === 'object') {
          flatten(obj[key], newKey);
        } else {
          result[newKey] = obj[key];
        }
      }
    }
  }

  flatten(jsonData);

  return result;
}

// 示例数据
let jsonData = {
  "name": "John",
  "age": 30,
  "address": {
    "street": "123 Main St",
    "city": "New York",
    "country": "USA"
  },
  "hobbies": ["reading", "traveling"],
  "friends": [
    {
      "name": "Alice",
      "age": 28
    },
    {
      "name": "Bob",
      "age": 32
    }
  ]
};

// 调用函数展开JSON数据
let flattenedData = flattenJSON(jsonData);

console.log(flattenedData);

{
  "name": "John",
  "age": 30,
  "address.street": "123 Main St",
  "address.city": "New York",
  "address.country": "USA",
  "hobbies[0]": "reading",
  "hobbies[1]": "traveling",
  "friends[0].name": "Alice",
  "friends[0].age": 28,
  "friends[1].name": "Bob",
  "friends[1].age": 32
