图像标签示例

本章节对图像标签AK/SK方式使用SDK进行示例说明。

  • 图像标签示例代码只需将AK/SK信息替换为实际AK/SK,代码中可以使用ImageTaggingReq中的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。
  • 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. 图像标签调用示例代码如下:
    package com.huaweicloud.sdk.test;
     
    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.region.ImageRegion;
    import com.huaweicloud.sdk.image.v2.*;
    import com.huaweicloud.sdk.image.v2.model.*;
                               
    public class RunImageTaggingSolution {
     
        public static void main(String[] args) {
           // 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HUAWEICLOUD_SDK_AK和HUAWEICLOUD_SDK_SK
            String ak = System.getenv("HUAWEICLOUD_SDK_AK");
            String sk = System.getenv("HUAWEICLOUD_SDK_SK");
            ICredential auth = new BasicCredentials()
                    .withAk(ak)
                    .withSk(sk);
            ImageClient client = ImageClient.newBuilder()
                    .withCredential(auth)
                    .withRegion(ImageRegion.valueOf("XXXX"))   //此处替换为您开通服务的区域
                    .build();
            RunImageTaggingRequest request = new RunImageTaggingRequest();
            ImageTaggingReq body = new ImageTaggingReq();
            body.withLimit(50);
            body.withThreshold(95f);
            body.withLanguage("zh");
            body.withUrl("https://XXX.jpg");  //此处替换为公网可以访问的图片地址
            request.withBody(body);
            try {
                RunImageTaggingResponse response = client.runImageTagging(request);
                System.out.println(response.toString());
            } 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,控制台返回200即表示程序执行成功。相关参数说明请参考图像标签API
    class RunImageTaggingResponse {
        result: class ImageTaggingResponseResult {
            tags: [class ImageTaggingItemBody {
                confidence: 98.00
                type: 树
                tag: 树
                i18nTag: class ImageTaggingItemBodyI18nTag {
                    zh: 树
                    en: Tree
                }
                i18nType: class ImageTaggingItemBodyI18nType {
                    zh: 树
                    en: Tree
                }
                instances: []
            }]
        }
    }
    
    Process finished with exit code 0
