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。
项目链接:https://github.com/yihong0618/running_page
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 } = result
records.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 = [] } = t
logs.forEach(log => {
if(isEmpty(log))return
const { stats: { endTime, kmDistance } } = log
const { 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 = year
mapValue.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 = year
mapValue.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
最新动态
骑行、跑步接口都只请求一次,同年同月同日的骑行、跑步数据放在一起,最后按endTime
字段的时间倒序返回结果。
getRecentUpdates.js
文件链接 https://github.com/CatsAndMice/keep/blob/master/src/getRecentUpdates.js
const getRunning = require('./getRunning');
const getCycling = require('./getCycling');
const { isEmpty, getYmdHms, toArray } = require('medash');
module.exports = async (token) => {
if (isEmpty(token)) return
const recentUpdateMap = new Map();
const result = await Promise.all([getRunning(token), getCycling(token)]);
result.forEach((r) => {
if (isEmpty(r)) return;
const records = r.records || [];
if (isEmpty(r.records)) return;
records.forEach(rs => {
rs.logs.forEach(l => {
const { stats } = l;
if (isEmpty(stats)) return;
// 运动距离小于1km 则忽略该动态
if (stats.kmDistance < 1) return;
const { year, month, date, } = getYmdHms(stats.endTime);
const key = `${year}年${month + 1}月${date}日`;
const mapValue = recentUpdateMap.get(key);
const value = `${stats.name} ${stats.kmDistance}km`;
if (mapValue) {
mapValue.data.push(value)
} else {
recentUpdateMap.set(key, {
date: key,
endTime: stats.endTime,
data: [
value
]
});
}
})
})
})
return toArray(recentUpdateMap.values()).sort((a, b) => {
return b.endTime - a.endTime
})
}
得到的数据是这样的:
[
{
date: '2023年8月12',
endTime: 1691834351501,
data: [
'户外跑步 99km',
'户外骑行 99km'
]
},
//...
]
同样的要先获取token,在src/index.js
文件:
const login = require('./login');
const getRecentUpdates = require('./getRecentUpdates');
//省略
const getFirstPageRecentUpdates = async () => {
const diff = Math.abs(Date.now() - query.date);
if (diff > two) {
const token = await login(data);
query.token = token;
query.date = Date.now();
}
return await getRecentUpdates(query.token);
}
//省略
最新动态这个接口还是简单的。
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。

最后的话
贵在坚持,做好「简单而正确」的事情,坚持是一项稀缺的能力,不仅仅是运动、写文章,在其他领域,也是如此。
这段时间对投资、理财小有研究,坚持运动也是一种对身体健康的投资。
又完成了一篇文章,奖励自己一顿火锅。
