Obtaining the Logging Configuration of a Bucket (SDK for Java)

Function

This API returns the logging configuration of a bucket.

If you have any questions during development, post them on the Issues page of GitHub.

Restrictions

To obtain the logging configuration of a bucket, you must be the bucket owner or have the required permission (obs:bucket:GetBucketLogging in IAM or GetBucketLogging in a bucket policy). For details, see Introduction to OBS Access Control, IAM Custom Policies, and Creating a Custom Bucket Policy.
The mapping between OBS regions and endpoints must comply with what is listed in Regions and Endpoints.

Method

obsClient.getBucketLogging(final BaseBucketRequest request)

Request Parameters

**Table 1** List of request parameters
Parameter	Type	Mandatory (Yes/No)	Description
request	BaseBucketRequest	Yes	Explanation: Request parameters for obtaining the logging configurations of a bucket. For details, see Table 2.

**Table 2** BaseBucketRequest
Parameter	Type	Mandatory (Yes/No)	Description
bucketName	String	Yes	Explanation: Bucket name. Restrictions: A bucket name must be unique across all accounts and regions. A bucket name: Must be 3 to 63 characters long and start with a digit or letter. Lowercase letters, digits, hyphens (-), and periods (.) are allowed. Cannot be formatted as an IP address. Cannot start or end with a hyphen (-) or period (.). Cannot contain two consecutive periods (..), for example, my..bucket. Cannot contain periods (.) and hyphens (-) adjacent to each other, for example, my-.bucket or my.-bucket. If you repeatedly create buckets of the same name in the same region, no error will be reported and the bucket attributes comply with those set in the first creation request. Default value: None

Responses

**Table 3** BucketLoggingConfiguration
Parameter	Type	Mandatory (Yes/No)	Description
agency	String	Yes if you configure bucket logging	Explanation: Name of the IAM agency created by the owner of the target bucket for OBS. You can select an existing IAM agency or create one. For details about how to create an agency, see Creating an IAM Agency. Restrictions: By default, the IAM agency only requires the PutObject permission to upload logs to the target bucket. If default encryption is enabled for the target bucket, the agency also requires the KMS Administrator permission in the region where the target bucket is located. Default value: None
targetBucketName	String	No	Explanation: Name of the bucket for storing log files. Restrictions: This bucket must be in the same region as the bucket with logging enabled. A bucket name must be unique across all accounts and regions. A bucket name: Must be 3 to 63 characters long and start with a digit or letter. Lowercase letters, digits, hyphens (-), and periods (.) are allowed. Cannot be formatted as an IP address. Cannot start or end with a hyphen (-) or period (.). Cannot contain two consecutive periods (..), for example, my..bucket. Cannot contain periods (.) and hyphens (-) adjacent to each other, for example, my-.bucket or my.-bucket. If you repeatedly create buckets of the same name in the same region, no error will be reported and the bucket attributes comply with those set in the first creation request. Default value: None
logfilePrefix	String	No	Explanation: Name prefix for log files stored in the target bucket. Value range: The value must contain 1 to 1,024 characters. Default value: None
targetGrantsList	List<GrantAndPermission>	No	Explanation: Permission information list of grantees, which defines grantees and their permissions for log files. For details, see Table 4.

**Table 4** GrantAndPermission
Parameter	Type	Mandatory (Yes/No)	Description
grantee	GranteeInterface	Yes	Explanation: Grantees (users or user groups). For details, see Table 5.
permission	Permission	Yes	Explanation: Permissions to grant. Value range: See Table 8. Default value: None
delivered	boolean	No	Explanation: Whether the bucket ACL is applied to all objects in the bucket. Value range: true: The bucket ACL is applied to all objects in the bucket. false: The bucket ACL is not applied to any objects in the bucket. Default value: false

**Table 5** GranteeInterface
Parameter	Type	Mandatory (Yes/No)	Description
CanonicalGrantee	CanonicalGrantee	Yes	Explanation: Grantee (user) information. For details, see Table 6.
GroupGrantee	GroupGrantee	Yes	Explanation: Grantee (user group) information. Value range: See Table 7. Default value: None

**Table 6** CanonicalGrantee
Parameter	Type	Mandatory (Yes/No)	Description
grantId	String	Yes if Type is set to GranteeUser	Explanation: Account (domain) ID of the grantee. Value range: To obtain the account ID, see How Do I Get My Account ID and User ID? Default value: None
displayName	String	No	Parameter description: Account name of the grantee. Value range: To obtain the account name, see How Do I Get My Account ID and User ID? Default value: None

**Table 7** GroupGrantee
Constant	Description
ALL_USERS	All users.
AUTHENTICATED_USERS	Authorized users. This constant is deprecated.
LOG_DELIVERY	Log delivery group. This constant is deprecated.

**Table 8** Permission
Constant	Default Value	Description
PERMISSION_READ	READ	Read permission. A grantee with this permission for a bucket can obtain the list of objects, multipart uploads, bucket metadata, and object versions in the bucket. A grantee with this permission for an object can obtain the object content and metadata.
PERMISSION_WRITE	WRITE	Write permission. A grantee with this permission for a bucket can upload, overwrite, and delete any object or part in the bucket. This permission is not available for objects.
PERMISSION_READ_ACP	READ_ACP	Permission to read an ACL. A grantee with this permission can obtain the ACL of a bucket or object. A bucket or object owner has this permission for their bucket or object by default.
PERMISSION_WRITE_ACP	WRITE_ACP	Permission to modify an ACL. A grantee with this permission can update the ACL of a bucket or object. A bucket or object owner has this permission for their bucket or object by default. This permission allows the grantee to change the access control policies, meaning the grantee has full control over a bucket or object.
PERMISSION_FULL_CONTROL	FULL_CONTROL	Full control access, including read and write permissions for a bucket and its ACL, or for an object and its ACL. A grantee with this permission for a bucket has READ, WRITE, READ_ACP, and WRITE_ACP permissions for the bucket. A grantee with this permission for an object has READ, WRITE, READ_ACP, and WRITE_ACP permissions for the object.

Code Examples

This example returns the logging configuration of bucket examplebucket.
