首先安装依赖

npm install node-schedule
npm install @types/node-schedule

引入模块

import * as schedule from 'node-schedule';

这种就是定时执行

   schedule.scheduleJob(new Date(2022,0,19,21,19,30),()=>{console.log('success');});

这种就是周期执行，关于怎么写corn这里就不赘述了 

schedule.scheduleJob('42 * * * *',()=>{console.log('success');
})
