开发中常见的时间与时间戳间相互转换的需要,如下是基于系统 api 的 import systemDateTime from '@ohos.systemDateTime'; 实现;
具体实现如下:
import systemDateTime from '@ohos.systemDateTime'/*公共方法类*/
export class PublicUtils {/*** 时间戳转时间* PublicUtils.getDateTime(systemDateTime.getTime(), 'yyyy-MM-dd HH:mm:ss')* @param time 时间戳(默认获取当前时间)* @param type 时间格式(默认'yyyy-MM-dd HH:mm')* @returns*/static getDateTime(time: number | null, type: string | null): string {let date = new Date(systemDateTime.getTime())if (time) {date = new Date(time)}// 获取时间const year = date.getFullYear().toString()let month = (date.getMonth() + 1).toString()let day = date.getDate().toString()let hour = date.getHours().toString()let min = date.getMinutes().toString()let seconds = date.getSeconds().toString()// 补位month = month.length === 1 ? `0${month}` : monthday = day.length === 1 ? `0${day}` : dayhour = hour.length === 1 ? `0${hour}` : hourmin = min.length === 1 ? `0${min}` : minseconds = seconds.length === 1 ? `0${seconds}` : seconds// 默认格式:年月日type = type ? type : 'yyyy-MM-dd'// 格式转换let timeStr = `${year}-${month}-${day}` // 默认 yyyy-mm-ddif (type === 'yyyy-MM-dd HH:mm:ss') {timeStr = `${year}-${month}-${day} ${hour}:${min}:${seconds}`} else if (type === 'yyyy-MM-dd HH:mm') {timeStr = `${year}-${month}-${day} ${hour}:${min}`} else if (type === 'yyyy-MM-dd') {timeStr = `${year}-${month}-${day}`} else if (type === 'yyyy-MM') {timeStr = `${year}-${month}`} else if (type === 'HH:mm:ss') {timeStr = `${hour}:${min}:${seconds}`} else if (type === 'HH:mm') {timeStr = `${hour}:${min}`}// callbackreturn timeStr}
