如何将JSON对象中的所有值都放入具有特定键、深键的数组中

function flattenJSON(json, key, deepKey, result) {
  if (typeof json !== 'object') {
    result.push({ [key]: json });
  } else if (Array.isArray(json)) {
    json.forEach((item, index) => {
      flattenJSON(item, `${key}[${index}]`, deepKey, result);
    });
  } else {
    for (let prop in json) {
      if (json.hasOwnProperty(prop)) {
        const newKey = deepKey ? `${key}.${prop}` : prop;
        flattenJSON(json[prop], newKey, deepKey, result);
      }
    }
  }
}

// 示例JSON对象
const json = {
  "name": "John",
  "age": 30,
  "address": {
    "street": "123 Main St",
    "city": "New York"
  },
  "hobbies": ["reading", "painting"],
  "friends": [
    {
      "name": "Alice",
      "age": 28
    },
    {
      "name": "Bob",
      "age": 32
    }
  ]
};

const result = [];
flattenJSON(json, '', true, result);
console.log(result);

[
  { 'name': 'John' },
  { 'age': 30 },
  { 'address.street': '123 Main St' },
  { 'address.city': 'New York' },
  { 'hobbies[0]': 'reading' },
  { 'hobbies[1]': 'painting' },
  { 'friends[0].name': 'Alice' },
  { 'friends[0].age': 28 },
  { 'friends[1].name': 'Bob' },
  { 'friends[1].age': 32 }
]
