该代码片段实现了将文件重命名为格式202307011034788.png(年月日时分毫秒.ext)

const fs = require('fs');

const date = new Date();

const addPrefix = (time) => {
    if (time.length == 1) {
        return '00' + time;
    }
    if (time.length == 2) {
        return '0' + time;
    }
    return time;
}

const add = (time) => {
    if (time.length == 1) {
        return '0' + time;
    }
    return time;
}

const year = date.getFullYear().toString();
const month = (date.getMonth() + 1).toString();
const day = date.getDate().toString();
const hour = date.getHours().toString();
const mins = date.getMinutes().toString();
const sec = date.getMilliseconds().toString();


const res = year + add(month) + add(day) + add(hour) + add(mins) + addPrefix(sec);

const filePath = process.argv[2];

fs.rename(filePath, res + '.png', (err, res) => {
    console.log(err);
});
