如何检查对象键是否符合条件递归模板类型？

function checkObjectKeys(obj, template) {
  for (let key in obj) {
    if (typeof key !== 'string') {
      throw new Error('Object key must be a string');
    }
    if (typeof obj[key] === 'object' && obj[key] !== null) {
      checkObjectKeys(obj[key], template);
    }
  }
}

// 示例用法
const obj = {
  key1: 'value1',
  key2: {
    subKey1: 'subValue1',
    subKey2: {
      subSubKey1: 'subSubValue1'
    }
  }
};

const template = {
  key: 'string',
  value: 'any',
  children: 'object'
};

try {
  checkObjectKeys(obj, template);
  console.log('Object keys are valid');
} catch (error) {
  console.error('Object keys are not valid:', error.message);
}
