NodeJS深度嵌套json比较不区分大小写的键/值对

function compareJsonIgnoreCase(json1, json2) {
  if (typeof json1 !== 'object' || typeof json2 !== 'object') {
    return json1 === json2;
  }
  
  // 比较对象的键/值对
  for (let key1 in json1) {
    if (!json1.hasOwnProperty(key1)) {
      continue;
    }

    let value1 = json1[key1];
    let value2 = json2[key1.toLowerCase()]; // 将键转换为小写形式

    if (typeof value1 === 'object' && typeof value2 === 'object') {
      // 递归比较嵌套的JSON对象
      if (!compareJsonIgnoreCase(value1, value2)) {
        return false;
      }
    } else if (String(value1).toLowerCase() !== String(value2).toLowerCase()) {
      // 比较键/值对的值时不区分大小写
      return false;
    }
  }

  // 检查第二个JSON对象是否有额外的键
  for (let key2 in json2) {
    if (json2.hasOwnProperty(key2) && !json1.hasOwnProperty(key2.toLowerCase())) {
      return false;
    }
  }

  return true;
}

// 示例用法
const json1 = {
  name: 'John',
  age: 30,
  address: {
    city: 'New York',
    country: 'USA'
  }
};

const json2 = {
  NAME: 'JOHN',
  AGE: 30,
  ADDRESS: {
    CITY: 'NEW YORK',
    COUNTRY: 'USA'
  }
};

console.log(compareJsonIgnoreCase(json1, json2)); // 输出: true
