如何使用PHP和阿里云OCR识别营业执照经营范围？

// 引入SDK的核心文件
require_once "<path_to_sdk_core>/autoload.php";

use DefaultProfile;
use DefaultAcsClient;
use RequestV20180120RecognizeBusinessLicenseRequest;

// 配置AK信息
$accessKeyId = "<your_access_key_id>";  // 替换为你的AccessKeyId
$accessKeySecret = "<your_access_key_secret>";  // 替换为你的AccessKeySecret
$regionId = "cn-hangzhou";  // 替换为你的RegionId

// 创建DefaultAcsClient实例并初始化
$profile = DefaultProfile::getProfile($regionId, $accessKeyId, $accessKeySecret);
DefaultProfile::addEndpoint("cn-hangzhou", "cn-hangzhou", "ocr", "ocr.cn-hangzhou.aliyuncs.com");
$client = new DefaultAcsClient($profile);

// 创建API请求并设置参数
$request = new RecognizeBusinessLicenseRequest();
$request->setAcceptFormat("json");  // 识别结果以json格式返回

// 读取营业执照图片并进行Base64编码
$imagePath = "<path_to_image>";  // 替换为营业执照图片的路径
$imageData = base64_encode(file_get_contents($imagePath));

$request->setImageURL($imageData);

// 发起API请求并解析结果
$response = $client->getAcsResponse($request);
$result = json_decode($response->getBody(), true);

// 输出经营范围
echo $result['Data']['Trade'] . "
";
