使用python删除S3中对象的所有版本？
使用python删除S3中对象的所有版本？
提问于 2017-10-18 21:32:08
我有一个版本化的存储桶，希望从桶中删除对象(及其所有版本)。但是，当我尝试从控制台中删除对象时，S3只是添加了一个删除标记，但没有执行硬删除。
是否可以使用特定的键删除对象的所有版本(硬删除)？：
s3resource = boto3.resource('s3')
bucket = s3resource.Bucket('my_bucket')
obj = bucket.Object('my_object_key')
# I would like to delete all versions for the object like so:
obj.delete_all_versions()
# or delete all versions for all objects like so:
bucket.objects.delete_all_versions()回答 12

作为@jarmod答案的补充，我开发了一种解决方法来“硬删除”一个对象(包括删除标记的对象)；
def get_all_versions(bucket, filename):
s3 = boto3.client('s3')
keys = ["Versions", "DeleteMarkers"]
results = []
for k in keys:
response = s3.list_object_versions(Bucket=bucket)[k]
to_delete = [r["VersionId"] for r in response if r["Key"] == filename]
results.extend(to_delete)
return results
bucket = "YOUR BUCKET NAME"
file = "YOUR FILE"
for version in get_all_versions(bucket, file):
s3.delete_object(Bucket=bucket, Key=file, VersionId=version)Stack Overflow用户

其他回答分别删除对象。使用delete_objects boto3调用和批处理删除更有效。请参阅以下函数的代码，该函数收集所有对象并在1000批中删除：
bucket = 'bucket-name'
s3_client = boto3.client('s3')
object_response_paginator = s3_client.get_paginator('list_object_versions')
delete_marker_list = []
version_list = []
for object_response_itr in object_response_paginator.paginate(Bucket=bucket):
if 'DeleteMarkers' in object_response_itr:
for delete_marker in object_response_itr['DeleteMarkers']:
delete_marker_list.append({'Key': delete_marker['Key'], 'VersionId': delete_marker['VersionId']})
if 'Versions' in object_response_itr:
for version in object_response_itr['Versions']:
version_list.append({'Key': version['Key'], 'VersionId': version['VersionId']})
for i in range(0, len(delete_marker_list), 1000):
response = s3_client.delete_objects(
Bucket=bucket,
Delete={
'Objects': delete_marker_list[i:i+1000],
'Quiet': True
}
)
print(response)
for i in range(0, len(version_list), 1000):
response = s3_client.delete_objects(
Bucket=bucket,
Delete={
'Objects': version_list[i:i+1000],
'Quiet': True
}
)
