使用PHP编写代码实现对接百度智能摄像头API的方法

<?php
// 设置API Key和Secret Key
$apiKey = 'your_api_key';
$secretKey = 'your_secret_key';

// 设置API请求的URL
$url = 'https://aip.baidubce.com/rest/2.0/image-classify/v1/body_attr';

// 设置请求参数
$data = array(
    'image' => base64_encode(file_get_contents('your_image_path')),
    'image_type' => 'BASE64',
);

// 设置HTTP请求头
$headers = array(
    'Content-Type: application/x-www-form-urlencoded',
);

// 生成签名
$sign = strtoupper(md5($url . '?' . http_build_query($data) . $secretKey));

// 拼接请求URL
$url = $url . '?' . http_build_query($data) . '&access_token=' . $apiKey . '&sign=' . $sign;

// 创建CURL请求
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

// 执行请求并获取API返回结果
$response = curl_exec($ch);
if (curl_errno($ch)) {
    echo 'Error: ' . curl_error($ch);
} else {
    echo 'Response: ' . $response;
}

// 关闭CURL请求
curl_close($ch);
?>
