Node.js 应用---定时给自己发送邮件

参照传智播客的视频所写代码。

js代码：

//引用superagent包，用于服务器发送http请求
const request = require('superagent');
//导入cheerio包 解析http
const cheerio = require('cheerio');
//导入 art-template
const template = require('art-template');
//导入PATH
const path = require('path');
//导入nodemaler发送邮件的包
const nodemailer = require('nodemailer');
//导入定时任务包
var schedule = require('node-schedule');

function getDate(){
    return new Promise((resolve , reject)=>{
        //现在的时间
        const today = new Date();
        //认识的时间
        const meet = new Date("**-**-**");
        //认识的天数
        const count = Math.floor((today - meet)/1000/60/60/24);
        //今天的日期
        const format = today.getFullYear() + " / " +(today.getMonth()+1) + " / " + today.getDate();
        const dayDate = {
            count,
            format
        }
        // console.log(daydate);
        resolve(dayDate);
    });   
}
// getDate();

//请求墨迹天气的数据
function getMojiData(){
    return new Promise((resolve , reject)=>{
