PHP와 Alibaba Cloud OCR을 사용하여 빠른 배송 추적 번호를 식별하는 방법은 무엇입니까?

require '/path/to/vendor/autoload.php'; // 引入阿里云的SDK

// 配置阿里云的Access Key和Secret Key
AlibabaCloud::accessKeyClient('{your access key}', '{your secret key}')

    ->asDefaultClient();

// 调用阿里云OCR服务进行快递单号识别
function recognizeExpressNumber($imagePath) {
