名人识别示例

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。
