はじめに
この記事は前回の続きです。
まだFitbit Web APIを実行したことがない方は以下の記事を参考にしてください。
やること
今回はWeb APIよりステップ（歩数）の情報を取得してみようと思います。
API情報
公式リファレンスを見ると以下のエンドポイントでSteps（歩数）の取得ができるようです。
また、このエンドポイントはcalories , distance , elevation , floors , steps
をresourceに指定することで、それぞれデータを取得することができるようです。
パラメータの指定方法
| パラメータ | 指定 | 説明 |
|---|---|---|
| user-id | 必須 | 現在ログインしているユーザーの場合は「-」(ダッシュ) を使用。 |
| resource | 必須 |
calories , distance , elevation , floors , steps のいずれかを指定。 |
| date | 必須 |
yyyy-MM-dd または todayのいずれかを指定 |
| detail-level | オプション | 詳細レベルを指定。1min , 5min , 15min
|
| start-time | オプション | 開始時間を指定。HH:mm
|
| end-time | オプション | 終了時間を指定。HH:mm
|
データの取得
.envの各値は前回の記事を参考に設定してください。
.env
CLIENT_ID=
ACCESS_TOKEN=
REFRESH_TOKEN=
getSteps.jsというファイルを作成します。（中身はURLの組み立て部分が変わっているだけで前回とほぼ同じです）
require('dotenv').config();
const axios = require('axios');
const fs = require('fs');
const path = require('path');
async function refreshAccessToken() {
const url = 'https://api.fitbit.com/oauth2/token';
const clientId = process.env.CLIENT_ID;
const refreshToken = process.env.REFRESH_TOKEN;
const body = new URLSearchParams();
body.append('grant_type', 'refresh_token');
body.append('client_id', clientId);
body.append('refresh_token', refreshToken);
const config = {
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
}
};
try {
const response = await axios.post(url, body.toString(), config);
const { access_token, refresh_token } = response.data;
updateEnvFile(clientId, access_token, refresh_token);
console.log('Access token and refresh token updated.');
return access_token;
} catch (error) {
console.error('Error refreshing token:', error.response.data);
}
}
function updateEnvFile(clientId, accessToken, refreshToken) {
const envPath = path.join(__dirname, '.env');
const envContents = `CLIENT_ID=${clientId}\nACCESS_TOKEN=${accessToken}\nREFRESH_TOKEN=${refreshToken}\n`;
fs.writeFileSync(envPath, envContents, 'utf8');
console.log('.env file has been updated with new tokens.');
}
async function getSteps(date = 'today', detail_level = '1min', start_time = '05:00', end_time = '06:59') {
const accessToken = await refreshAccessToken();
const url = `https://api.fitbit.com/1//user/-/activities/steps/date/${date}/1d/${detail_level}/time/${start_time}/${end_time}.json`
try {
const response = await axios.get(url, {
headers: {
'Authorization': `Bearer ${accessToken}`
}
});
return response.data;
} catch (error) {
console.error('Error fetching steps rate data:', error.response.data);
}
}
(async () => {
const stepsData = await getSteps(); // 今日の1日分の歩数データを取得
console.log(JSON.stringify(stepsData));
})();
実行
node getSteps.js
結果
ちょっと長いので折りたたんでいます。

const url = `https://api.fitbit.com/1//user/-/activities/steps/date/${date}/1d/${detail_level}/time/${start_time}/${end_time}.json`
実行した際のURLは以下のようになります。
https://api.fitbit.com/1//user/-/activities/steps/date/today/1d/1min/time/05:00/06:59.json
上記を実行した際の挙動としては「コードを実行した日の05:00−06:59の間の1分間の歩数集計データを取得」となります。
