简单弄一个format

/**

• @description 格式化时间
• @param {number/String} timestamp 时间戳（毫秒）
• @param {string} formatString 想要返回的格式

• @returns {string} - 格式化后的日期字符串
  */
  export const format = (timestamp, formatString) => {
  const date = new Date(timestamp);
  const year = date.getFullYear();
  const month = padZero(date.getMonth() + 1); // 月份是从0开始的，所以需要加1
  const day = padZero(date.getDate());
  const hours = padZero(date.getHours());
  const minutes = padZero(date.getMinutes());
  const seconds = padZero(date.getSeconds());

  // 填充前导零的函数
  function padZero(number) {
  return number.toString().padStart(2, '0');
  }

  // 替换格式字符串中的占位符
  return formatString
  .replace('yyyy', year)
  .replace('MM', month)
  .replace('dd', day)
  .replace('hh', hours)
  .replace('mm', minutes)
  .replace('ss', seconds);

}

第二种方法
// utils/formatDate.js
export function formatDate(timestamp) {
const date = new Date(timestamp);
const year = date.getFullYear();
const month = String(date.getMonth() + 1).padStart(2, '0');
const day = String(date.getDate()).padStart(2, '0');
const hours = String(date.getHours()).padStart(2, '0');
const minutes = String(date.getMinutes()).padStart(2, '0');
const seconds = String(date.getSeconds()).padStart(2, '0');

return ${year}-${month}-${day} ${hours}:${minutes}:${seconds};
}
