“S3”对象没有属性“get_object_lock_configuration”

编程问答 2022-05-01

问题描述

我正在尝试实现对象锁定功能，但函数（get/put_object_lock_configuration）不可用：

>>> import boto3
>>> boto3.__version__
'1.17.64'
>>> client = boto3.client('s3')
>>> client.get_object_lock_configuration
Traceback (most recent call last):
  File "<stdin>",line 1,in <module>
  File "/usr/lib/python3.6/site-packages/botocore/client.py",line 553,in __getattr__
    self.__class__.__name__,item)
AttributeError: 'S3' object has no attribute 'get_object_lock_configuration'

>>> client.get_object_lock_configuration(Bucket='tst',ExpectedBucketowner='tst')
Traceback (most recent call last):
  File "<stdin>",item)
AttributeError: 'S3' object has no attribute 'get_object_lock_configuration'

编辑： 对象锁定功能未在 python 中显示（选项卡选项卡）：

>>> client.get_object_
client.get_object_acl(      client.get_object_tagging(  client.get_object_torrent(

>>> client.put_object
client.put_object(          client.put_object_acl(      client.put_object_tagging(

解决方法

get_object_lock_configuration 是 function 而非属性。

你需要这样称呼它：

response = client.get_object_lock_configuration(
    Bucket='string',ExpectedBucketOwner='string'
)
,

调用函数客户端的语法。get_object_lock_configuration：

response = client.get_object_lock_configuration(
    Bucket='string',ExpectedBucketOwner='string'
)

调用函数客户端的语法。put_object_lock_configuration：

response = client.put_object_lock_configuration(
    Bucket='string',ObjectLockConfiguration={
        'ObjectLockEnabled': 'Enabled','Rule': {
            'DefaultRetention': {
                'Mode': 'GOVERNANCE'|'COMPLIANCE','Days': 123,'Years': 123
            }
        }
    },RequestPayer='requester',Token='string',ContentMD5='string',ExpectedBucketOwner='string'
)

要了解更多信息，请参阅此：https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/s3.html#S3.Client.put_object_lock_configuration

编辑：

示例代码：

import json
import boto3

client = boto3.client('s3')

response = client.get_object_lock_configuration(
Bucket='anynewname')

print(response)

输出语法：

{
    'ObjectLockConfiguration': {
        'ObjectLockEnabled': 'Enabled','Years': 123
            }
        }
    }
}

注意：如果没有在bucket上设置对象锁配置，会报错。
