Object Storage Service:Configure hotlink protection using Python SDK V2 to prevent other websites from referencing OSS files

You can use the following code to set hotlink protection.

import argparse
import alibabacloud_oss_v2 as oss

# Create a command line argument parser and describe the script's purpose: set the hotlink protection configuration for a bucket
parser = argparse.ArgumentParser(description="put bucket referer sample")

# Define command line arguments, including the required region, bucket name, and optional endpoint
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():
    # Parse command line arguments to obtain user input values
    args = parser.parse_args()

    # Load access credential information from environment variables for authentication
    credentials_provider = oss.credentials.EnvironmentVariableCredentialsProvider()

    # Create a configuration object using the SDK default configuration and set the authentication provider
    cfg = oss.config.load_default()
    cfg.credentials_provider = credentials_provider

    # Set the region property of the configuration object based on the user-provided command line arguments
    cfg.region = args.region

    # If a custom endpoint is provided, modify the endpoint parameter in the configuration object
    if args.endpoint is not None:
        cfg.endpoint = args.endpoint

    # Use the preceding configuration to initialize the OSS client and prepare for interaction with OSS
    client = oss.Client(cfg)

    # Send a request to set the hotlink protection configuration for the specified bucket
    result = client.put_bucket_referer(oss.PutBucketRefererRequest(
            bucket=args.bucket,  # Bucket name
            referer_configuration=oss.RefererConfiguration(
                allow_empty_referer=True,  # Whether to allow an empty Referer, the default is True
                allow_truncate_query_string=False,  # Whether to allow truncating the query string, the default is False
                truncate_path=False,  # Whether to truncate the path, the default is False
                referer_list=oss.RefererList(
                    referers=['http://www.aliyun.com', 'https://www.aliyun.com'],  # Allowed Referer list
                ),
                referer_blacklist=oss.RefererBlacklist(
                    referers=['http://www.refuse.com', 'http://www.refuse1.com'],  # Rejected Referer blacklist
                ),
            ),
    ))

    # Print the status code and request ID of the operation result to confirm the request status
    print(f'status code: {result.status_code},'
          f' request id: {result.request_id},'
          )

# Call the main function to start the processing logic when the script is directly run
if __name__ == "__main__":
    main()  # Script entry point, control program flow starts here

You can use the following code to retrieve the hotlink protection configuration.

parser = argparse.ArgumentParser(description="get bucket referer 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():
    # Parse command line arguments to obtain user input values
    args = parser.parse_args()

    # Load access credential information from environment variables for authentication
    credentials_provider = oss.credentials.EnvironmentVariableCredentialsProvider()

    # Create a configuration object using the SDK default configuration and set the authentication provider
    cfg = oss.config.load_default()
    cfg.credentials_provider = credentials_provider
    
    # Set the region property of the configuration object based on the user-provided command line arguments
    cfg.region = args.region

    # If a custom endpoint is provided, modify the endpoint parameter in the configuration object
    if args.endpoint is not None:
        cfg.endpoint = args.endpoint

    # Use the preceding configuration to initialize the OSS client and prepare for interaction with OSS
    client = oss.Client(cfg)

    # Send a request to obtain the hotlink protection configuration for the specified bucket
    result = client.get_bucket_referer(oss.GetBucketRefererRequest(
            bucket=args.bucket,  # Bucket name
    ))

    # Print the status code, request ID, and hotlink protection configuration details of the operation result to confirm the request status and configuration details
    print(f'status code: {result.status_code},'
          f' request id: {result.request_id},'
          f' allow empty referer: {getattr(result.referer_configuration, "allow_empty_referer", "Not set")},'
