利用PHP與七牛雲儲存介面實現圖片的物件偵測與智慧分類的方法

require_once 'path/to/sdk/autoload.php';

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

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

// 生成上传 Token
$bucket = 'YOUR_BUCKET_NAME';

// 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();

// 获取上传后的图片地址

// 构建物体检测的请求参数

// 打印物体标签
