Setting Cross-Bucket Replication

Feature description

This API (PUT Bucket replication) is used to set the cross-bucket replication rule for a bucket.

Method prototype

put_bucket_replication(Bucket, ReplicationConfiguration={}, **kwargs)

Request example

# -*- coding=utf-8
from qcloud_cos import CosConfig
from qcloud_cos import CosS3Client
import sys
import os
import logging

# In most cases, set the log level to INFO. If you need to debug, you can set it to DEBUG and the SDK will print information about the communication with the server.
logging.basicConfig(level=logging.INFO, stream=sys.stdout)

# 1. Set user attributes such as secret_id, secret_key, and region. Appid has been removed from CosConfig and thus needs to be specified in Bucket, which is formatted as BucketName-Appid.
secret_id = os.environ['COS_SECRET_ID']     #  User `SecretId`. We recommend you use a sub-account key and follow the principle of least privilege to reduce risks. For information about how to obtain a sub-account key, visit https://www.tencentcloud.com/document/product/598/37140?from_cn_redirect=1.
secret_key = os.environ['COS_SECRET_KEY']   # User `SecretKey`. We recommend you use a sub-account key and follow the principle of least privilege to reduce risks. For information about how to obtain a sub-account key, visit https://www.tencentcloud.com/document/product/598/37140?from_cn_redirect=1.
