本文介绍如何通过 TOS Java SDK 查询 Bucket 中基于 ObjectSet 标签配置的 QoS 与容量配额规则。

注意事项

如果未配置按标签的 QoS 与容量配额规则，服务端可能返回 ObjectSetQuotaConfigNotExist。

通过子账号调用时，需要具备当前 Bucket 的 tos:GetObjectSetQuotaByTag 权限。

代码示例

        String accessKey = System.getenv("TOS_ACCESS_KEY");​
        String secretKey = System.getenv("TOS_SECRET_KEY");​
        String bucket = System.getenv("TOS_BUCKET");​
​
        TOSV2 tos = new TOSV2ClientBuilder().build(region, endpoint, accessKey, secretKey);​
​
        try {​
            GetObjectSetQuotaByTagInput input = GetObjectSetQuotaByTagInput.builder()​
                    .bucket(bucket)​
                    .build();​
            GetObjectSetQuotaByTagOutput output = tos.getObjectSetQuotaByTag(input);​
            int ruleCount = output.getRules() == null ? 0 : output.getRules().size();​
            System.out.println("getObjectSetQuotaByTag succeed, rule count: " + ruleCount);​
            System.out.println("RequestID: " + output.getRequestInfo().getRequestId());​
        } catch (TosClientException e) {​
            System.out.println("getObjectSetQuotaByTag failed");​
            System.out.println("Message: " + e.getMessage());​
            if (e.getCause() != null) {​
                e.getCause().printStackTrace();​
            }​
        } catch (TosServerException e) {​

            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("getObjectSetQuotaByTag failed");​
            System.out.println("unexpected exception, message: " + t.getMessage());​
        }​
    }​
