const now = new Date();

const year = now.getFullYear();
const month = String(now.getMonth() + 1).padStart(2, '0'); // 月份从0开始，需要加1
const day = String(now.getDate()).padStart(2, '0');
const hours = String(now.getHours()).padStart(2, '0');
const minutes = String(now.getMinutes()).padStart(2, '0');
const seconds = String(now.getSeconds()).padStart(2, '0');

const formattedDate = `${year}-${month}-${day} ${hours}:${minutes}:${seconds}`;
console.log(formattedDate); // 输出格式: "2023-04-05 14:30:15"

const now = new Date();

const formattedDate = now.toLocaleDateString();
const formattedTime = now.toLocaleTimeString();

console.log(`${formattedDate} ${formattedTime}`); // 输出格式根据本地设置，例如 "2023/4/5 下午2:30:15"

import { format } from 'date-fns';

const now = new Date();
const formattedDate = format(now, 'yyyy-MM-dd HH:mm:ss');
