Obtaining the Bucket Logging Configuration

Functions

After logging is enabled for a bucket, you can call this API to query the logging configuration of the bucket. .

Constraints

• You can store logs in the logged bucket or another bucket. However, the log storage bucket and logged bucket must belong to the same account and region.
• By default, buckets in the Infrequent Access or Archive storage class cannot be used to store log files. Stored log files occupy storage space in the bucket and are billed the same way as user-stored data.

Authorization Information

To call this API, you must be the bucket owner or have the permission to obtain the logging configuration of a bucket. You are advised to use IAM or bucket policies for authorization. For details about OBS authorization methods, see Differences Between OBS Permissions Control Methods.

• If you use IAM for authorization, you need to use either role/policy-based authorization or identity policy-based authorization and configure the required permissions:
  • If you use role/policy-based authorization (IAM v3 APIs in the old IAM version), you need to grant the obs:bucket:GetBucketLogging permission. For details, see Creating a Custom IAM Policy.
  • If you use identity policy-based authorization (IAM v5 APIs in the new IAM version), you need to grant the obs:bucket:getBucketLogging permission, as shown in the following table. For details, see Creating a Custom IAM Identity Policy.

    Action	Access Level	Resource Type (*: Required)	Condition Key	Alias	Dependencies
    obs:bucket:getBucketLogging	Read	bucket *	g:EnterpriseProjectId g:ResourceTag/<tag-key>	-	-
    		-	obs:EpochTime obs:SourceIp obs:TlsVersion obs:CustomDomain

• If you use bucket policies for authorization, you need to grant the obs:bucket:GetBucketLogging permission. For details, see Creating a Custom Bucket Policy.

Using SDKs to Call APIs

You are advised to use OBS SDKs to call APIs. SDKs encapsulate APIs to simplify development. You can call SDK API functions to access OBS without manually calculating signatures.
