How to use OSS SDK for Python V2 to manage Block Public Access at the bucket level-Object Storage Service(OSS)-阿里云帮助中心

Use OSS SDK for Python V2 to enable, query, and delete the Block Public Access configuration at the bucket level.

All examples use alibabacloud_oss_v2 and load credentials from environment variables. The sample region is China (Hangzhou) (cn-hangzhou). If you access OSS from another Alibaba Cloud service in the same region, use an internal endpoint instead. For region-to-endpoint mappings, see OSS regions and endpoints.

Prerequisites

Before you begin, ensure that you have:

An OSS bucket
Access credentials configured as environment variables

Enable Block Public Access for a bucket

Call put_bucket_public_access_block with block_public_access=True to enable Block Public Access.

import argparse
import alibabacloud_oss_v2 as oss

parser = argparse.ArgumentParser(description="put bucket public access block sample")
parser.add_argument('--region', help='The region in which the bucket is located.', required=True)
parser.add_argument('--bucket', help='The name of the bucket.', required=True)
parser.add_argument('--endpoint', help='The domain names that other services can use to access OSS')
parser.add_argument('--block_public_access',
                    help='Specifies whether to enable Block Public Access. '
                         'true: enables Block Public Access. '
                         'false (default): disables Block Public Access.',
                    default=False, type=bool)

def main():
    args = parser.parse_args()

    # Load credentials from environment variables
    credentials_provider = oss.credentials.EnvironmentVariableCredentialsProvider()

    cfg = oss.config.load_default()
    cfg.credentials_provider = credentials_provider
    cfg.region = args.region

    if args.endpoint is not None:
        cfg.endpoint = args.endpoint

    client = oss.Client(cfg)

    result = client.put_bucket_public_access_block(oss.PutBucketPublicAccessBlockRequest(
            bucket=args.bucket,
            public_access_block_configuration=oss.PublicAccessBlockConfiguration(
                block_public_access=args.block_public_access,
            ),
    ))

    print(f'status code: {result.status_code},'
          f' request id: {result.request_id},'
          )

if __name__ == "__main__":
    main()

Get the Block Public Access configuration of a bucket

Call get_bucket_public_access_block to retrieve the current Block Public Access configuration. The response includes block_public_access from result.public_access_block_configuration: True if Block Public Access is enabled, False if disabled, or "Not set" if no configuration exists.

import argparse
import alibabacloud_oss_v2 as oss

parser = argparse.ArgumentParser(description="get bucket public access block sample")
parser.add_argument('--region', help='The region in which the bucket is located.', required=True)
parser.add_argument('--bucket', help='The name of the bucket.', required=True)
parser.add_argument('--endpoint', help='The domain names that other services can use to access OSS')

def main():
    args = parser.parse_args()

    credentials_provider = oss.credentials.EnvironmentVariableCredentialsProvider()

    cfg = oss.config.load_default()
    cfg.credentials_provider = credentials_provider
    cfg.region = args.region

    if args.endpoint is not None:
        cfg.endpoint = args.endpoint

    client = oss.Client(cfg)

    result = client.get_bucket_public_access_block(oss.GetBucketPublicAccessBlockRequest(
            bucket=args.bucket,
    ))

    print(f'status code: {result.status_code},'
          f' request id: {result.request_id},'
          f' block public access: {getattr(result.public_access_block_configuration, "block_public_access", "Not set")},'
          )

if __name__ == "__main__":
    main()

Delete the Block Public Access configuration of a bucket

Call delete_bucket_public_access_block to remove the Block Public Access configuration from a bucket.

import argparse
import alibabacloud_oss_v2 as oss

parser = argparse.ArgumentParser(description="delete bucket public access block sample")
parser.add_argument('--region', help='The region in which the bucket is located.', required=True)
parser.add_argument('--bucket', help='The name of the bucket.', required=True)
parser.add_argument('--endpoint', help='The domain names that other services can use to access OSS')

def main():
    args = parser.parse_args()

    credentials_provider = oss.credentials.EnvironmentVariableCredentialsProvider()

    cfg = oss.config.load_default()
    cfg.credentials_provider = credentials_provider
    cfg.region = args.region

    if args.endpoint is not None:
        cfg.endpoint = args.endpoint

    client = oss.Client(cfg)

    result = client.delete_bucket_public_access_block(oss.DeleteBucketPublicAccessBlockRequest(
            bucket=args.bucket,
    ))

    print(f'status code: {result.status_code},'
          f' request id: {result.request_id},'
          )

if __name__ == "__main__":
    main()
