食物营养素数据库 API

使用 Fetch API 获取食物营养数据

// 设置您的API密钥
const API_KEY = 'your_api_key_here';
const APP_KEY = 'your_app_key_here';

// 查询大米的营养信息
fetch('https://api.nutritiondb.com/api/v1/food/1001', {
    headers: {
        'x-api-key': API_KEY,
        'x-app-key': APP_KEY
    }
})
.then(response => response.json())
.then(data => {
    if (data.status === 'success') {
        console.log('大米营养信息:', data.data.nutrition);
    }
})
.catch(error => console.error('查询错误:', error));

使用 Requests 库调用 API

# 导入必要的库
import requests

# API配置
API_KEY = 'your_api_key_here'
APP_KEY = 'your_app_key_here'
BASE_URL = 'https://api.nutritiondb.com/api/v1'

# 设置请求头
headers = {
    'x-api-key': API_KEY,
    'x-app-key': APP_KEY
}

# 查询小麦的营养信息
response = requests.get(f'{BASE_URL}/food/1003', headers=headers)

if response.status_code == 200:
    data = response.json()
    if data['status'] == 'success':
        print('小麦营养信息:', data['data']['nutrition'])
else:
    print('查询失败:', response.status_code)

使用 HttpClient 调用 API

import java.net.URI;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
import java.util.HashMap;
import java.util.Map;

public class NutritionApiClient {
    // API配置
    private static final String API_KEY = "your_api_key_here";
    private static final String APP_KEY = "your_app_key_here";
    private static final String BASE_URL = "https://api.nutritiondb.com/api/v1";
    
    public static void main(String[] args) throws Exception {
        // 创建HTTP客户端
        HttpClient client = HttpClient.newHttpClient();
        
        // 构建请求
        HttpRequest request = HttpRequest.newBuilder()
            .uri(new URI(BASE_URL + "/food/1001"))
            .header("x-api-key", API_KEY)
            .header("x-app-key", APP_KEY)
            .GET()
            .build();
        
        // 发送请求并处理响应
        HttpResponse response = client.send(request, HttpResponse.BodyHandlers.ofString());
        
        if (response.statusCode() == 200) {
            System.out.println("响应内容: " + response.body());
        } else {
            System.out.println("请求失败: " + response.statusCode());
        }
    }
}

使用 cURL 扩展调用 API

<?php
// API配置
$API_KEY = 'your_api_key_here';
$APP_KEY = 'your_app_key_here';
$BASE_URL = 'https://api.nutritiondb.com/api/v1';

// 要查询的食物ID
$foodId = '1001';

// 初始化cURL
$ch = curl_init();

// 设置cURL选项
curl_setopt($ch, CURLOPT_URL, $BASE_URL . '/food/' . $foodId);
curl_setopt($ch, CURLOPT_HTTPHEADER, [
    'x-api-key: ' . $API_KEY,
    'x-app-key: ' . $APP_KEY
]);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// 执行请求
$response = curl_exec($ch);

// 检查错误
if ($response === false) {
    echo 'cURL错误: ' . curl_error($ch);
} else {
    // 解析JSON响应
    $data = json_decode($response, true);
    
    if ($data['status'] === 'success') {
        echo '营养信息: ';
        print_r($data['data']['nutrition']);
    } else {
        echo 'API错误: ' . $data['message'];
    }
}

// 关闭cURL
curl_close($ch);
?>
