TOS 支持日志分析功能，支持通过日志服务，检索分析您访问 TOS 过程中产生的访问日志。通过 TOS Java SDK 您可以设置日志分析功能的相关配置。

设置实时日志配置规则 #

您可以通过 TOS Java SDK 的 putBucketRealTimeLog 接口设置桶的实时日志配置。

示例代码 #

以下代码展示如何设置桶的实时日志配置规则。

        String secretKey = System.getenv("TOS_SECRET_KEY"); 

        String bucketName = "bucket-example";

        String realTimeLogRole = "your real time log role";

        TOSV2 tos = new TOSV2ClientBuilder().build(region, endpoint, accessKey, secretKey);

                    .setConfiguration(new AccessLogConfiguration()
                            .setUseServiceTopic(true)
                            .setTlsProjectID(tlsProjectId)
                            .setTlsTopicID(tlsTopicId));
            PutBucketRealTimeLogInput input = new PutBucketRealTimeLogInput().setBucket(bucketName)
                    .setConfiguration(configuration);
            PutBucketRealTimeLogOutput output = tos.putBucketRealTimeLog(input);
            System.out.println("putBucketRealTimeLog succeed");
        } catch (TosClientException e) {
            // 操作失败，捕获客户端异常，一般情况是请求参数错误，此时请求并未发送
            System.out.println("putBucketRealTimeLog failed");
            System.out.println("Message: " + e.getMessage());
            if (e.getCause() != null) {
                e.getCause().printStackTrace();
            }
        } catch (TosServerException e) {
            // 操作失败，捕获服务端异常，可以获取到从服务端返回的详细错误信息
            System.out.println("putBucketRealTimeLog 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) {
            // 作为兜底捕获其他异常，一般不会执行到这里
            System.out.println("putBucketRealTimeLog failed");
            System.out.println("unexpected exception, message: " + t.getMessage());
        }
    }
}

        try{
            DeleteBucketRealTimeLogInput input = new DeleteBucketRealTimeLogInput().setBucket(bucketName);
            DeleteBucketRealTimeLogOutput output = tos.deleteBucketRealTimeLog(input);
            System.out.println("deleteBucketRealTimeLog succeed, " + output);
        } catch (TosClientException e) {
            // 操作失败，捕获客户端异常，一般情况是请求参数错误，此时请求并未发送
