node 控制 树莓派做的天气闹钟

在成都上班，下雨天堵车，迟到的概率会很大。
正好手上有一块树莓派 ，做了一个晴雨闹钟。
下雨天 早上 7:00叫我起床
晴天 早上 7:30叫我起床
将自己喜欢的歌曲放在一个文件夹中，随机播放，防止听腻

以下是代码

const UID = "U785B76FC9"; // 测试用 用户ID，请更换成您自己的用户ID
const KEY = "4r9bergjetiv1tsd"; // 测试用 key，请更换成您自己的 Key
let LOCATION = "双流"; // 除拼音外，还可以使用 v3 id、汉语等形式
let Api = require('./lib/api.js');
let api = new Api(UID, KEY);
let rainRegexp = /雨/;
let exec = require('child_process').exec;

let fs = require("fs");
let schedule = require("node-schedule");

function alarmClockTime(isRain) {
let today = new Date();
let Y = today.getFullYear();
let M = today.getMonth();
let D = today.getDate();
let week = today.getDay();
if (week === 0 || week === 6) {
return new Date(Y, M, D, 9, 30, 0);
}
if (isRain) {
return new Date(Y, M, D, 7, 0, 0);
}
return new Date(Y, M, D, 7, 30, 0);
}

//调用音乐
function playMusic() {
let shellStr;
let musicArray;
try {
musicArray = fs.readdirSync("/media/hd/music/alarm/");
let fileNmae=musicArray[Math.floor(musicArray.length * Math.random())].replace(/ /g,"\\ ");
shellStr = "mplayer /media/hd/music/alarm/" +fileNmae;
} catch (err) {
shellStr = "mplayer /media/hd/music/qiyue.mp3";
}

console.log(shellStr);

exec(shellStr, function (err, data) {
if (err) {
console.log(err);
return;
}
console.log("播放完成");
})
}

function setAlarmClock(time) {
schedule.scheduleJob(time, function () {
playMusic();
});
}

/**
* 获取天气信息
*/
function getWetherInfo() {
let getNowWeather = api.getWeather("/weather/now.json", {
location: LOCATION
});

let getNextWeather = api.getWeather("/weather/daily.json", {
location: LOCATION
});

Promise.all([getNowWeather, getNextWeather]).then(function (data) {
let nowWeatherText = data[0].results[0].now.text;
let dayWeatherText = data[1].results[0].daily[0].text_day;
console.log(new Date() + " ：" + dayWeatherText);
if (rainRegexp.test(nowWeatherText) || rainRegexp.test(dayWeatherText)) {
//当天有雨 提前设置闹钟
setAlarmClock(alarmClockTime(true));
} else {
//没有雨 延后设置闹钟
setAlarmClock(alarmClockTime());
}
}).catch(function (err) {
console.log(err);
setAlarmClock(alarmClockTime(true));
});
}

schedule.scheduleJob("0 50 6 * * *", function () {
getWetherInfo();
});
