javascript时间戳转日期格式以及时区问题解决

// 时间(可传入时间戳或时间对象)， 格式，时区，默认北京时区为东8
export function parseTime (time, cFormat, zone = 8) {
  if (arguments.length === 0) {
    return null
  }
  const format = cFormat || '{y}-{m}-{d} {h}:{i}:{s}'
  let date
  if (typeof time === 'object') {
    date = time
  } else {
    if (('' + time).length === 10) time = parseInt(time) * 1000
    date = new Date(time)
  }
  // 时区调整
  const utc = time + new Date(time).getTimezoneOffset() * 60000
  const wishTime = utc + (3600000 * zone)
  date = new Date(wishTime)
  const formatObj = {
    y: date.getFullYear(),
    m: date.getMonth() + 1,
    d: date.getDate(),
    h: date.getHours(),
    i: date.getMinutes(),
    s: date.getSeconds(),
    a: date.getDay()
  }
  const timeStr = format.replace(/{(y|m|d|h|i|s|a)+}/g, (result, key) => {
    let value = formatObj[key]
    // Note: getDay() returns 0 on Sunday
    if (key === 'a') { return ['日', '一', '二', '三', '四', '五', '六'][value] }
    if (result.length > 0 && value < 10) {
      value = '0' + value
    }
    return value || 0
  })
  return timeStr
}
