使用python删除S3中对象的所有版本? [英] Delete all versions of an object in S3 using python?

问题描述

我有一个版本化的存储桶，想从存储桶中删除对象(及其所有版本).但是，当我尝试从控制台删除对象时，S3只会添加删除标记，而不会执行硬删除.

I have a versioned bucket and would like to delete the object (and all of its versions) from the bucket. However, when I try to delete the object from the console, S3 simply adds a delete marker but does not perform a hard delete.

是否可以使用特定键删除对象的所有版本(硬删除)?

Is it possible to delete all versions of the object (hard delete) with a particular key?:

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()

推荐答案

作为 @jarmod 的答案的补充，这是我开发出一种变通方法来硬删除"对象(包括删除标记的对象)的方法；

As a supplement to @jarmod's answer, here is a way I developed a workaround to "hard deleting" an object (with delete markered objects included);

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)
