Obtaining the Public Access Block Configuration of a Bucket

Functions

This API returns the public access block configuration of an OBS bucket.

To perform this operation, you must have the GetBucketPublicAccessBlock permission. The bucket owner can perform this operation by default and can grant this permission to others by using a bucket policy or a user policy.

Authorization Information

To call this API, you must be the bucket owner or have the permission to obtain the public access block 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:GetBucketPublicAccessBlock 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:getBucketPublicAccessBlock permission, as shown in the following table. For details, see Creating a Custom IAM Identity Policy.

    obs:bucket:getBucketPublicAccessBlock	Read	bucket *	g:EnterpriseProjectId g:ResourceTag/<tag-key>	-	-

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