如何使用 OSS2 设置特定路径下所有对象的公开访问权限并使其继承该权限？

from oss2 import Bucketfrom oss2.fields import Policybucket = Bucket(oss2.Auth(), "your-endpoint", "your-bucket-name")policy = Policy()policy.rules = [    {        "effect": "Allow",        "principal": "*",        "action": ["GetObject"],        "resource": ["acs:oss://your-bucket-name/sample/video/*"],    }]bucket.put_bucket_policy(policy)
