利用PHP与七牛云存储接口实现图片的物体检测和智能分类的方法

require_once 'path/to/sdk/autoload.php';
use QiniuAuth;
use QiniuStorageUploadManager;

// 需要填写你的 Access Key 和 Secret Key
$accessKey = 'YOUR_ACCESS_KEY';
$secretKey = 'YOUR_SECRET_KEY';

// 构建鉴权对象
$auth = new Auth($accessKey, $secretKey);

// 生成上传 Token
$bucket = 'YOUR_BUCKET_NAME';
$token = $auth->uploadToken($bucket);

// 要上传文件的本地路径
$filePath = 'path/to/image.jpg';

// 上传到七牛云存储
$uploadMgr = new UploadManager();
list($ret, $err) = $uploadMgr->putFile($token, null, $filePath);

// 获取上传后的图片地址
$imageUrl = $ret['key'];

// 构建物体检测的请求参数
$requestUrl = 'http://ai.qiniuapi.com/v1/image/realtime?detectType=3&returnLabels=1';

// 发送请求
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $requestUrl);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode(['url' => $imageUrl]));
curl_setopt($curl, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
$result = curl_exec($curl);
curl_close($curl);

// 解析返回的结果
$resultArray = json_decode($result, true);
$labels = $resultArray['result'][0]['labels'];

// 打印物体标签
foreach ($labels as $label) {
    echo $label['name'] . "
";
}

// 构建智能分类的请求参数
$requestUrl = 'http://ai.qiniuapi.com/v1/image/censor?scenes=';
$scenes = ['pulp', 'terror', 'politician', 'ads', 'live', 'sensitive'];
$requestUrl .= implode(',', $scenes);

// 发送请求
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $requestUrl);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode(['url' => $imageUrl]));
curl_setopt($curl, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
$result = curl_exec($curl);
curl_close($curl);

// 解析返回的结果
$resultArray = json_decode($result, true);
$censorResults = $resultArray['result'];

// 打印分类结果
foreach ($censorResults as $scene => $censorResult) {
    echo $scene . ': ' . ($censorResult['suggestion'] == 0 ? '正常' : '不确定') . "
";
