AWS IoT一键设备API服务

接入教程

1. 登录AWS控制台并启用IoT服务
2. 注册您的IoT设备并获取凭证
3. 调用设备API进行设备管理
4. 参考示例代码实现基本操作
5. 根据业务需求扩展功能

列出设备

python

import requests

url = 'https://api.example.com/devices'
headers = {
    'Content-Type': 'application/json',
    'Authorization': 'Bearer YOUR_API_KEY'
}

response = requests.get(url, headers=headers)
if response.status_code == 200:
    devices = response.json()
    print(f'Found {len(devices)} devices')
else:
    print(f'Error: {response.status_code}')
    print(response.text)

获取设备详细信息

php

<?php
$url = 'https://api.example.com/devices/{deviceId}';
$headers = [
    'Content-Type: application/json',
    'Authorization: Bearer YOUR_API_KEY'
];

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$response = curl_exec($ch);
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);

if ($httpCode == 200) {
    $device = json_decode($response, true);
    echo 'Device name: ' . $device['name'];
} else {
    echo 'Error: ' . $httpCode;
    echo $response;
}

curl_close($ch);
?>

更新设备状态

javascript

const fetch = require('node-fetch');

async function updateDeviceState(deviceId, state) {
    const url = `https://api.example.com/devices/${deviceId}/state`;
    const options = {
        method: 'PUT',
        headers: {
            'Content-Type': 'application/json',
            'Authorization': 'Bearer YOUR_API_KEY'
        },
        body: JSON.stringify({ state: state })
    };

    try {
        const response = await fetch(url, options);
        if (response.ok) {
            const data = await response.json();
            console.log('Device state updated successfully:', data);
        } else {
            console.error('Error:', response.status);
            console.error(await response.text());
        }
    } catch (error) {
        console.error('Request failed:', error);
    }
}

// Example usage
// updateDeviceState('device123', 'active');

常见问题

如何获取API密钥？

您需要先在AWS控制台创建IAM用户并分配必要的权限，然后生成访问密钥ID和秘密访问密钥。

API调用频率有限制吗？

是的，AWS IoT 1-Click API有默认的速率限制。具体限制取决于您的AWS账户和服务配置。

支持哪些认证方式？

主要支持AWS签名版本4（SigV4）认证，使用IAM凭证对请求进行签名。
