翻拍识别示例

本章节对翻拍识别AK/SK方式使用SDK进行示例说明。

• 翻拍识别示例代码只需将AK/SK信息替换为实际AK/SK，代码中可以使用初始化RunRecaptureDetectReq中的Image或Url配置图像信息（image和url参数二选一），示例中以url为例，配置完成后运行即可。
• endpoint是华为云各服务应用区域和各服务的终端节点，详情请查看地区和终端节点 。

1. 翻拍识别调用示例代码如下：

   <?php
   namespace HuaweiCloud\SDK\Image\V2\Model;
   require_once "vendor/autoload.php";
   use HuaweiCloud\SDK\Core\Auth\BasicCredentials;
   use HuaweiCloud\SDK\Core\Http\HttpConfig;
   use HuaweiCloud\SDK\Core\Exceptions\ConnectionException;
   use HuaweiCloud\SDK\Core\Exceptions\RequestTimeoutException;
   use HuaweiCloud\SDK\Core\Exceptions\ServiceResponseException;
   use HuaweiCloud\SDK\Image\V2\ImageClient;
      // 认证用的ak和sk硬编码到代码中或者明文存储都有很大的安全风险，建议在配置文件或者环境变量中密文存放，使用时解密，确保安全；
      // 本示例以ak和sk保存在环境变量中来实现身份验证为例，运行本示例前请先在本地环境中设置环境变量CLOUD_SDK_AK和CLOUD_SDK_SK。
   $ak = getenv('CLOUD_SDK_AK');
   $sk = getenv('CLOUD_SDK_SK');
    //image.cn-north-4.myhuaweicloud.com替换为您开通服务区域的终端节点
   $endpoint = "https://image.cn-north-4.myhuaweicloud.com"; 
   $projectId = "";
   $credentials = new BasicCredentials($ak,$sk,$projectId);
   $config = HttpConfig::getDefaultConfig();
   $config->setIgnoreSslVerification(true);
   $client = ImageClient::newBuilder(new ImageClient)
     ->withHttpConfig($config)
     ->withEndpoint($endpoint)
     ->withCredentials($credentials)
     ->build();
   $request = new RunRecaptureDetectRequest();
   $body = new RecaptureDetectReq();
   $body->setThreshold(0.9);
   $body->setImage("输入图片,使用base64编码");
   $request->setBody($body);
   try {
     $response = $client->RunRecaptureDetect($request);
     echo "\n";
     echo $response;
   } catch (ConnectionException $e) {
     $msg = $e->getMessage();
     echo "\n". $msg ."\n";
   } catch (RequestTimeoutException $e) {
     $msg = $e->getMessage();
     echo "\n". $msg ."\n";
   } catch (ServiceResponseException $e) {
     echo "\n";
     echo $e->getHttpStatusCode(). "\n";
     echo $e->getRequestId(). "\n";
     echo $e->getErrorCode() . "\n";
     echo $e->getErrorMsg() . "\n";
   }

2. 识别结果输出到控制台表示执行成功。
