将UTC日期转换为日期时间字符串Javascript

function utcToLocal(utcDateString) {
  // 将UTC日期字符串转换为Date对象
  var utcDate = new Date(utcDateString);

  // 获取本地时区偏移量
  var offset = utcDate.getTimezoneOffset() * 60 * 1000;

  // 将UTC日期转换为本地日期
  var localDate = new Date(utcDate.getTime() + offset);

  // 格式化日期时间字符串
  var year = localDate.getFullYear();
  var month = localDate.getMonth() + 1;
  var day = localDate.getDate();
  var hour = localDate.getHours();
  var minute = localDate.getMinutes();
  var second = localDate.getSeconds();

  // 格式化日期时间字符串
  var dateTimeString = year + '-' + month + '-' + day + ' ' + hour + ':' + minute + ':' + second;

  return dateTimeString;
}

// 示例用法
var utcDateString = '2022-01-01T00:00:00Z';
var localDateTimeString = utcToLocal(utcDateString);
console.log(localDateTimeString); // 输出：2022-1-1 8:0:0
