], code: 200, msg: '查询成功'};

const newsIds = data.rows.map(obj => obj.newsId);
console.log(newsIds);

输出结果将是一个包含所有newsId的数组：

[
  '1697141767175475201',
  '1696821743951872001',
  '1696155194749423617',
  '1696107814834475010',
  '1696099282974216194',
  '1671360627611361281',
  '1689915338070773762',
  '1689903109443244034',
  '1686014030571479042',
  '1686017217890197505'
]

你可以根据需要进一步处理这些newsId。
