核心功能模块详解
1. 卡路里追踪系统
基于app-ideas中的Calorie Counter项目，构建专业的营养管理模块：
class CalorieTracker {
constructor() {
this.foodDatabase = this.loadFoodData();
this.dailyIntake = 0;
this.dailyGoal = 2000; // 默认每日目标
}
// 加载食物数据库
async loadFoodData() {
try {
const response = await fetch('/data/food-database.json');
return await response.json();
} catch (error) {
console.error('Failed to load food database:', error);
return [];
}
}
// 搜索食物热量
searchFood(query) {
return this.foodDatabase.filter(food =>
food.name.toLowerCase().includes(query.toLowerCase())
).slice(0, 25); // 限制结果数量
}
// 添加食物记录
addFoodConsumption(food, quantity) {
const calories = food.calories * quantity;
this.dailyIntake += calories;
this.saveToLocalStorage();
return calories;
}
// 计算剩余热量
getRemainingCalories() {
return Math.max(0, this.dailyGoal - this.dailyIntake);
}
}
2. 运动追踪与数据分析
class WorkoutTracker {
constructor() {
this.workoutSessions = [];
this.currentSession = null;
}
// 开始训练会话
startWorkout(type) {
this.currentSession = {
type: type,
startTime: new Date(),
exercises: [],
caloriesBurned: 0
};
}
// 添加训练动作
addExercise(exercise, duration, intensity) {
if (!this.currentSession) return;
const calories = this.calculateCaloriesBurned(exercise, duration, intensity);
this.currentSession.exercises.push({
exercise,
duration,
intensity,
calories
});
this.currentSession.caloriesBurned += calories;
}
// 计算消耗热量
calculateCaloriesBurned(exercise, duration, intensity) {
const METValues = {
'running': 8, 'cycling': 7, 'swimming': 6, 'weightlifting': 3
};
const baseMET = METValues[exercise] || 3;
const adjustedMET = baseMET * intensity;
return Math.round(adjustedMET * duration / 60); // 估算热量消耗
}
// 结束训练并保存
endWorkout() {
if (!this.currentSession) return;
this.currentSession.endTime = new Date();
this.workoutSessions.push(this.currentSession);
this.saveToDatabase();
this.currentSession = null;
}
}
数据可视化与用户界面设计
健康数据仪表盘
运动进度追踪表
| 运动类型 | 持续时间 | 消耗热量 | 强度等级 |
|---|---|---|---|
| 跑步 | 30分钟 | 240 kcal | 高 |
| 瑜伽 | 45分钟 | 180 kcal | 中 |
| 力量训练 | 60分钟 | 300 kcal | 高 |
| 步行 | 60分钟 | 150 kcal | 低 |
高级功能与扩展
1. 机器学习健康预测
import pandas as pd
from sklearn.linear_model import LinearRegression
from sklearn.model_selection import train_test_split
class HealthPredictor:
def __init__(self):
self.model = LinearRegression()
self.trained = False
def prepare_training_data(self, health_data):
# 数据预处理和特征工程
features = pd.DataFrame(health_data)
features['date'] = pd.to_datetime(features['date'])
features['day_of_week'] = features['date'].dt.dayofweek
features['month'] = features['date'].dt.month
return features
def train_model(self, X, y):
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2)
self.model.fit(X_train, y_train)
self.trained = True
return self.model.score(X_test, y_test)
def predict_health_trend(self, current_data):
if not self.trained:
raise ValueError("Model not trained yet")
prediction = self.model.predict([current_data])
return prediction[0]
2. 个性化健康建议引擎
class HealthAdvisor {
constructor(userProfile) {
this.userProfile = userProfile;
this.recommendationRules = this.setupRules();
}
setupRules() {
return {
nutrition: {
underCalories: (data) => data.intake < data.goal * 0.8,
overCalories: (data) => data.intake > data.goal * 1.2,
proteinDeficit: (data) => data.protein < data.weight * 1.2
},
exercise: {
insufficient: (data) => data.weeklyExercise < 150,
excessive: (data) => data.weeklyExercise > 420,
varietyLacking: (data) => data.exerciseTypes < 3
}
};
}
generateRecommendations(healthData) {
const recommendations = [];
// 营养建议
if (this.recommendationRules.nutrition.underCalories(healthData)) {
recommendations.push({
category: 'nutrition',
message: '建议增加热量摄入，确保每日能量需求',
priority: 'high'
});
}
// 运动建议
if (this.recommendationRules.exercise.insufficient(healthData)) {
recommendations.push({
category: 'exercise',
message: '建议增加运动时间，每周至少150分钟中等强度运动',
priority: 'medium'
});
}
return recommendations.sort((a, b) => {
const priorityOrder = { high: 1, medium: 2, low: 3 };
return priorityOrder[a.priority] - priorityOrder[b.priority];
});
}
}
数据安全与隐私保护
健康数据加密存储
class HealthDataSecurity {
constructor() {
this.encryptionKey = this.generateEncryptionKey();
}
// 生成加密密钥
generateEncryptionKey() {
return crypto.getRandomValues(new Uint8Array(32));
}
// 加密健康数据
async encryptHealthData(data) {
const encoder = new TextEncoder();
const encodedData = encoder.encode(JSON.stringify(data));
const iv = crypto.getRandomValues(new Uint8Array(12));
const encryptedData = await crypto.subtle.encrypt(
{
name: 'AES-GCM',
iv: iv
},
await this.importKey(),
encodedData
);
return {
iv: Array.from(iv),
data: Array.from(new Uint8Array(encryptedData))
};
}
// 导入加密密钥
async importKey() {
return await crypto.subtle.importKey(
'raw',
this.encryptionKey,
{ name: 'AES-GCM' },
false,
['encrypt', 'decrypt']
);
}
}
性能优化策略
1. 数据缓存机制
class HealthDataCache {
constructor() {
this.cache = new Map();
this.maxSize = 100; // 最大缓存条目数
}
// 添加数据到缓存
set(key, data, ttl = 300000) { // 默认5分钟
if (this.cache.size >= this.maxSize) {
this.evictOldest();
}
this.cache.set(key, {
data: data,
timestamp: Date.now(),
ttl: ttl
});
}
// 从缓存获取数据
get(key) {
const item = this.cache.get(key);
if (!item) return null;
// 检查是否过期
if (Date.now() - item.timestamp > item.ttl) {
this.cache.delete(key);
return null;
}
return item.data;
}
// 清理最旧的缓存
evictOldest() {
let oldestKey = null;
let oldestTime = Infinity;
for (const [key, value] of this.cache.entries()) {
if (value.timestamp < oldestTime) {
oldestTime = value.timestamp;
oldestKey = key;
}
}
if (oldestKey) {
this.cache.delete(oldestKey);
}
}
}
2. 数据库查询优化
-- 创建优化的健康数据索引
CREATE INDEX idx_health_data_user_date
ON health_data (user_id, record_date DESC);
CREATE INDEX idx_exercise_sessions
ON exercise_sessions (user_id, session_type, duration);
-- 使用分区表管理历史数据
CREATE TABLE health_data_partitioned (
id SERIAL PRIMARY KEY,
user_id INTEGER NOT NULL,
record_date DATE NOT NULL,
calories_intake INTEGER,
calories_burned INTEGER,
steps_count INTEGER,
heart_rate INTEGER
) PARTITION BY RANGE (record_date);
-- 创建月度分区
CREATE TABLE health_data_2025_09 PARTITION OF health_data_partitioned
FOR VALUES FROM ('2025-09-01') TO ('2025-10-01');
测试与质量保证
单元测试示例
describe('CalorieTracker', () => {
let tracker;
beforeEach(() => {
tracker = new CalorieTracker();
// 模拟食物数据库
tracker.foodDatabase = [
{ name: 'Apple', calories: 95 },
{ name: 'Banana', calories: 105 },
{ name: 'Chicken Breast', calories: 165 }
];
});
test('should search food items correctly', () => {
const results = tracker.searchFood('apple');
expect(results).toHaveLength(1);
expect(results[0].name).toBe('Apple');
});
test('should calculate remaining calories correctly', () => {
tracker.dailyIntake = 1500;
tracker.dailyGoal = 2000;
expect(tracker.getRemainingCalories()).toBe(500);
});
test('should handle zero remaining calories', () => {
tracker.dailyIntake = 2500;
tracker.dailyGoal = 2000;
expect(tracker.getRemainingCalories()).toBe(0);
});
});
