Enabling Bucket Logging

If you have any questions during development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see the API Reference.

You can call ObsClient.setBucketLogging to enable bucket logging.

The source bucket and target bucket of logging must be in the same region.

If the bucket is in the OBS Infrequent Access or Archive storage class, it cannot be used as the target bucket.

Enabling Bucket Logging

Sample code:

// Hard-coded or plaintext AK/SK are risky. For security purposes, encrypt your AK/SK and store them in the configuration file or environment variables. In this example, the AK/SK are stored in environment variables for identity authentication. Before running this example, configure environment variables ACCESS_KEY_ID and SECRET_ACCESS_KEY_ID.
// Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/intl/en-us/usermanual-ca/ca_01_0003.html.
String ak = System.getenv("ACCESS_KEY_ID");
String sk = System.getenv("SECRET_ACCESS_KEY_ID");
String endPoint = "https://your-endpoint";
// Create an ObsClient instance.
ObsClient obsClient = new ObsClient(ak, sk, endPoint);

BucketLoggingConfiguration config = new BucketLoggingConfiguration();
// Set an agency. You need to create one on IAM.
config.setAgency("your agency");
config.setTargetBucketName("targetbucketname");
config.setLogfilePrefix("targetprefix");

obsClient.setBucketLogging("bucketname", config);

Setting ACLs for Objects to Be Logged

Sample code:

// Hard-coded or plaintext AK/SK are risky. For security purposes, encrypt your AK/SK and store them in the configuration file or environment variables. In this example, the AK/SK are stored in environment variables for identity authentication. Before running this example, configure environment variables ACCESS_KEY_ID and SECRET_ACCESS_KEY_ID.
// Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/intl/en-us/usermanual-ca/ca_01_0003.html.
String ak = System.getenv("ACCESS_KEY_ID");
String sk = System.getenv("SECRET_ACCESS_KEY_ID");
String endPoint = "https://your-endpoint";

// Create an ObsClient instance.
ObsClient obsClient = new ObsClient(ak, sk, endPoint);

String targetBucket = "targetbucketname"; 

// Configure logging.
BucketLoggingConfiguration config = new BucketLoggingConfiguration();
// Set an agency. You need to create one on IAM.
config.setAgency("your agency");
config.setTargetBucketName(targetBucket);
config.setLogfilePrefix("prefix");

// Grant the READ permission on the objects to be logged to all users. 
GrantAndPermission grant1 = new GrantAndPermission(GroupGrantee.ALL_USERS, Permission.PERMISSION_READ);
config.setTargetGrants(new GrantAndPermission[]{grant1});

obsClient.setBucketLogging("bucketname", config);
