本章节对名人识别AK/SK方式使用SDK进行示例说明。

名人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CelebrityRecognitionReq类的withUrl或withImage方法配置图像信息（image和url参数二选一），示例中以url为例，配置完成后运行即可。

1. 名人识别调用示例代码如下：

   package com.huaweicloud.sdk.test;
   
   import com.alibaba.fastjson.JSON;
   
   import com.huaweicloud.sdk.core.auth.ICredential;
   import com.huaweicloud.sdk.core.auth.BasicCredentials;
   import com.huaweicloud.sdk.core.exception.ConnectionException;
   import com.huaweicloud.sdk.core.exception.RequestTimeoutException;
   import com.huaweicloud.sdk.core.exception.ServiceResponseException;
   import com.huaweicloud.sdk.image.v2.ImageClient;
   import com.huaweicloud.sdk.image.v2.model.RunCelebrityRecognitionRequest;
   import com.huaweicloud.sdk.image.v2.region.ImageRegion;
   import com.huaweicloud.sdk.image.v2.model.CelebrityRecognitionReq;
   import com.huaweicloud.sdk.image.v2.model.RunCelebrityRecognitionResponse;
   
   
   public class RunCelebrityRecognitionSolution {
   
       public static void main(String[] args) {
           String ak = "<YOUR AK>";
           String sk = "<YOUR SK>";
   
           ICredential auth = new BasicCredentials()
                   .withAk(ak)
                   .withSk(sk);
   
           ImageClient client = ImageClient.newBuilder()
                   .withCredential(auth)
                   .withRegion(ImageRegion.valueOf("cn-north-1"))
                   .build();
           RunCelebrityRecognitionRequest request = new RunCelebrityRecognitionRequest();
           CelebrityRecognitionReq body = new CelebrityRecognitionReq();
           body.withThreshold(0f);
           body.withUrl("https://sdk-obs-source-save.obs.cn-north-4.myhuaweicloud.com/celebrity-recognition.jpg");
           request.withBody(body);
           try {
               RunCelebrityRecognitionResponse response = client.runCelebrityRecognition(request);
               System.out.println(response.getHttpStatusCode());
               System.out.println(JSON.toJSONString(response));
           } catch (ConnectionException e) {
               e.printStackTrace();
           } catch (RequestTimeoutException e) {
               e.printStackTrace();
           } catch (ServiceResponseException e) {
               e.printStackTrace();
               System.out.println(e.getHttpStatusCode());
               System.out.println(e.getErrorCode());
               System.out.println(e.getErrorMsg());
           }
       }
   }

2. 执行示例代码文件，控制台输出名人识别结果即表示程序执行成功。名人识别结果输出到控制台。
