本文介绍如何通过 TOS Java SDK 查询指定 ObjectSet 的标签集合。
注意事项
ObjectSet 必须存在。
通过子账号调用时，需要具备当前 Bucket 的 tos:GetObjectSetTagging 权限。
代码示例
import com.volcengine.tos.TOSV2;​
import com.volcengine.tos.TOSV2ClientBuilder;​
import com.volcengine.tos.TosClientException;​
import com.volcengine.tos.TosServerException;​
import com.volcengine.tos.model.bucket.GetObjectSetTaggingInput;​
import com.volcengine.tos.model.bucket.GetObjectSetTaggingOutput;​
import com.volcengine.tos.model.bucket.Tag;​
​
public class GetObjectSetTaggingExample {​
    public static void main(String[] args) {​
        String endpoint = System.getenv("TOS_ENDPOINT");​
        String region = System.getenv("TOS_REGION");​
        String accessKey = System.getenv("TOS_ACCESS_KEY");​
        String secretKey = System.getenv("TOS_SECRET_KEY");​
        String bucket = System.getenv("TOS_BUCKET");​
        String objectSetName = System.getenv("TOS_OBJECT_SET_NAME");​
​
        TOSV2 tos = new TOSV2ClientBuilder().build(region, endpoint, accessKey, secretKey);​
​
        try {​
            GetObjectSetTaggingInput input = GetObjectSetTaggingInput.builder()​
                    .bucket(bucket)​
                    .objectSetName(objectSetName)​
                    .build();​
            GetObjectSetTaggingOutput output = tos.getObjectSetTagging(input);​
            System.out.println("getObjectSetTagging succeed");​
            if (output.getTagSet() != null && output.getTagSet().getTags() != null) {​
                for (Tag tag : output.getTagSet().getTags()) {​
                    System.out.println("Tag: " + tag.getKey() + "=" + tag.getValue());​
                }​
            }​
            System.out.println("RequestID: " + output.getRequestInfo().getRequestId());​
        } catch (TosClientException e) {​
            System.out.println("getObjectSetTagging failed");​
            System.out.println("Message: " + e.getMessage());​
            if (e.getCause() != null) {​
                e.getCause().printStackTrace();​
            }​
        } catch (TosServerException e) {​
            System.out.println("getObjectSetTagging failed");​
            System.out.println("StatusCode: " + e.getStatusCode());​
            System.out.println("Code: " + e.getCode());​
            System.out.println("Message: " + e.getMessage());​
            System.out.println("RequestID: " + e.getRequestID());​
        } catch (Throwable t) {​
            System.out.println("getObjectSetTagging failed");​
            System.out.println("unexpected exception, message: " + t.getMessage());​
        }​
    }​
}​
