用Node.js吭哧吭哧撸一个运动主页

简单唠唠

某乎问题：人这一生，应该养成哪些好习惯？

问题链接：https://www.zhihu.com/question/460674063

如果我来回答肯定会有定期运动的字眼。

平日里也有煅练的习惯，时间久了后一直想把运动数据公开，可惜某运动软件未开放公共的接口出来。

幸运的是，在Github平台冲浪我发现了有同行和我有类似的想法，并且已经用Python实现了他自己的运动主页。

Python嘛简单，看明白后用Node.js折腾一波，自己撸两个接口玩玩。

完成的运动页面挂在我的博客网址。

梳理思路

平时跑步、骑行这两项活动多，所以我只需要调用这两个接口，再调用这两个接口前需要先登录获取到token。

1. 登陆接口: https://api.gotokeep.com/v1.1/users/login 请求方法:post   Content-Type: "application/x-www-form-urlencoded;charset=utf-8"2. 骑行数据接口：https://api.gotokeep.com/pd/v3/stats/detail?dateUnit=all&type=cycling&lastDate={last_date}请求方法: get   Content-Type: "application/x-www-form-urlencoded;charset=utf-8"Authorization：`Bearer ${token}`3. 跑步数据接口：https://api.gotokeep.com/pd/v3/stats/detail?dateUnit=all&type=running&lastDate={last_date}请求方法: get   Content-Type: "application/x-www-form-urlencoded;charset=utf-8"Authorization：`Bearer ${token}`

Node.js服务属于代理层，解决跨域问题并再对数据包裹一层逻辑处理，最后发给客户端。

不明白代理的同学可以看看这篇《Nginx之正、反向代理》

运动数据总和

请求跑步接口方法：

getRunning.js文件链接https://github.com/CatsAndMice/keep/blob/master/src/getRunning.js

const { headers } = require('./config');
const { isEmpty } = require("medash");
const axios = require('axios');module.exports = async (token, last_date = 0) => {if (isEmpty(token)) return {}headers["Authorization"] = `Bearer ${token}`;const result = await axios.get(`https://api.gotokeep.com/pd/v3/stats/detail?dateUnit=all&type=running&lastDate=${last_date}`, { headers })if (result.status === 200) {const { data: loginResult } = result;return loginResult.data;}return {};
}

请求骑行接口方法：

getRunning.js文件链接 https://github.com/CatsAndMice/keep/blob/master/src/getCycling.js

const { headers } = require('./config');
const { isEmpty } = require("medash");
const axios = require('axios');module.exports = async (token, last_date = 0) => {if (isEmpty(token)) return {}headers["Authorization"] = `Bearer ${token}`;const result = await axios.get(`https://api.gotokeep.com/pd/v3/stats/detail?dateUnit=all&type=cycling&lastDate=${last_date}`, { headers })if (result.status === 200) {const { data: loginResult } = result;return loginResult.data;}return {};
}

现在要计算跑步、骑行的总数据，因此需要分别请求跑步、骑行的接口获取到所有的数据。

getAllLogs.js文件链接https://github.com/CatsAndMice/keep/blob/master/src/getAllLogs.js

const { isEmpty } = require('medash');module.exports = async (token, firstResult, callback) => {if (isEmpty(firstResult)||isEmpty(token)) {console.warn('请求中断');return;}let { lastTimestamp, records = [] } = firstResult;while (1) {if (isEmpty(lastTimestamp)) break;const result = await callback(token, lastTimestamp)if (isEmpty(result)) break;const { lastTimestamp: lastTime, records: nextRecords } = resultrecords.push(...nextRecords);if (isEmpty(lastTime)) break;lastTimestamp = lastTime}return records
}

一个while循环干到底，所有的数据都会被push到records数组中。

返回的records数据再按年份分类计算某年的总骑行数或总跑步数，使用Map做这类事别提多爽了。

getYearTotal.js文件链接 https://github.com/CatsAndMice/keep/blob/master/src/getYearTotal.js

const { getYmdHms, mapToObj, each, isEmpty } = require('medash');
module.exports = (totals = []) => {const yearMap = new Map()totals.forEach((t) => {const { logs = [] } = tlogs.forEach(log => {if(isEmpty(log))returnconst { stats: { endTime, kmDistance } } = logconst { year } = getYmdHms(endTime);const mapValue = yearMap.get(year);if (mapValue) {yearMap.set(year, mapValue + kmDistance);return}yearMap.set(year, kmDistance);})})let keepRunningTotals = [];each(mapToObj(yearMap), (key, value) => {keepRunningTotals.push({ year: key, kmDistance:  Math.ceil(value) });})return keepRunningTotals.sort((a, b) => {return b.year - a.year;});
}

处理过后的数据是这样子的：

[{year:2023,kmDistance:99},{year:2022,kmDistance:66},//...
]

计算跑步、骑行的逻辑，唯一的变量为请求接口方法的不同，getAllLogs.js、getYearTotal.js我们可以复用。

骑行计算总和：

cycling.js文件链接https://github.com/CatsAndMice/keep/blob/master/src/cycling.js

const getCycling = require('./getCycling');
const getAllLogs = require('./getAllLogs');
const getYearTotal = require('./getYearTotal');module.exports = async (token) => {const result = await getCycling(token)const allCycling = await getAllLogs(token, result, getCycling);const yearCycling = getYearTotal(allCycling)return yearCycling
}

跑步计算总和：

run.js文件链接 https://github.com/CatsAndMice/keep/blob/master/src/run.js

const getRunning = require('./getRunning');
const getAllRunning = require('./getAllLogs');
const getYearTotal = require('./getYearTotal');module.exports = async (token) => {const result = await getRunning(token)// 获取全部的跑步数据const allRunning = await getAllRunning(token, result, getRunning);// 按年份计算跑步运动量const yearRunning = getYearTotal(allRunning)return yearRunning
}

最后一步，骑行、跑步同年份数据汇总。

src/index.js文件链接https://github.com/CatsAndMice/keep/blob/master/src/index.js

const login = require('./login');
const getRunTotal = require('./run');
const getCycleTotal = require('./cycling');
const { isEmpty, toArray } = require("medash");
require('dotenv').config();
const query = {token: '',date: 0
}
const two = 2 * 24 * 60 * 60 * 1000
const data = { mobile: process.env.MOBILE, password: process.env.PASSWORD };
const getTotal = async () => {const diff = Math.abs(Date.now() - query.date);if (diff > two) {const token = await login(data);query.token = token;query.date = Date.now();}//Promise.all并行请求const result = await Promise.all([getRunTotal(query.token), getCycleTotal(query.token)])const yearMap = new Map();if (isEmpty(result)) return;if (isEmpty(result[0])) return;result[0].forEach(r => {const { year, kmDistance } = r;const mapValue = yearMap.get(year);if (mapValue) {mapValue.year = yearmapValue.data.runKmDistance = kmDistance} else {yearMap.set(year, {year, data: {runKmDistance: kmDistance,cycleKmDistance: 0}})}})if (isEmpty(result[1])) return;result[1].forEach(r => {const { year, kmDistance } = r;const mapValue = yearMap.get(year);if (mapValue) {mapValue.year = yearmapValue.data.cycleKmDistance = kmDistance} else {yearMap.set(year, {year, data: {runKmDistance: 0,cycleKmDistance: kmDistance}})}})return toArray(yearMap.values())
}
module.exports = {getTotal
}

getTotal方法会将跑步、骑行数据汇总成这样：

[{year:2023,runKmDistance: 999,//2023年，跑步总数据cycleKmDistance: 666//2023年，骑行总数据},{year:2022,runKmDistance: 99,cycleKmDistance: 66},//...
]

每次调用getTotal方法都会调用login方法获取一次token。这里做了一个优化，获取的token会被缓存2天省得每次都调，调多了登陆接口会出问题。

//省略
const query = {token: '',date: 0
}
const two = 2 * 24 * 60 * 60 * 1000
const data = { mobile: process.env.MOBILE, password: process.env.PASSWORD };
const getTotal = async () => {const diff = Math.abs(Date.now() - query.date);if (diff > two) {const token = await login(data);query.token = token;query.date = Date.now();}//省略   
}//省略

express创建接口

运动主页由于我要将其挂到我的博客，因为端口不同会出现跨域问题，所以要开启跨源资源共享（CORS）。

app.use((req, res, next) => {res.setHeader("Access-Control-Allow-Origin", "*");res.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");res.setHeader('Content-Type', 'application/json;charset=utf8');next();
})

另外，我的博客网址使用的是https协议，Node.js服务也需要升级为https，否则会请求出错。以前写过一篇文章介绍Node.js升级https协议，不清楚的同学可以看看这篇《Node.js搭建Https服务》文章链接https://linglan01.cn/post/47。
