修改图片信息示例

本章节对修改图片信息AK/SK方式使用SDK进行示例说明。

修改图片信息示例代码只需将AK/SK信息替换为实际AK/SK,代码中可以使用RunModifyPictureReq类的setPath和setTags方法配置图像的路径和标签,配置完成后运行即可。

  1. 修改图片调用示例代码如下:
    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.imagesearch.v1.*;
    import com.huaweicloud.sdk.imagesearch.v1.model.*;
    import com.huaweicloud.sdk.imagesearch.v1.region.ImageSearchRegion;
     
    import java.util.HashMap;
    import java.util.Map;
     
    /**
     * 修改图像索引库中已存在的图片信息。
     */
    public class RunModifyPictureSolution {
        
        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);
            
            ImageSearchClient client = ImageSearchClient.newBuilder()
                .withCredential(auth)
                //设置region,示例中region为北京四
                .withRegion(ImageSearchRegion.valueOf("cn-north-4"))
                .build();
            RunModifyPictureRequest request = new RunModifyPictureRequest();
            //设置实例名称
            request.setInstanceName("instance-name");
            RunModifyPictureReq body = new RunModifyPictureReq();
            //图片URL路径,作为图片库中索引图片的ID。
            body.setPath("https://bucketname.obs.cn-north-4.myhuaweicloud.com/search-test.jpg");
            //自定义标签,格式为key:value对
            Map<String, String> tags = new HashMap<>();
            tags.put("animal", "dog");
            body.setTags(tags);
            request.setBody(body);
    
            try {
                RunModifyPictureResponse response = client.runModifyPicture(request);
                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,控制台输出修改图片信息结果即表示程序执行成功。修改图片信息结果输出到控制台。
