python-3.x - 无法从版本控制的 s3 存储桶中删除项目

Question

我正在尝试从 s3 存储桶中删除特定的 .jpg 文件。我尝试了许多不同的方法，例如 delete_object 和其他几个堆栈溢出答案。它们都没有正常工作，导致程序每次都以不同的退出代码崩溃。下面的代码不会使程序崩溃，但存储桶保持不变。有谁知道如何解决这个问题？

s3 = boto3.resource('s3')
s3.Object('my-bucket', 'label_file').delete()

打印调用响应时，这是打印到终端的消息。

Answer 1

您的 S3 存储桶启用了版本控制，因为您:

      'x-amz-delete-marker': 'true',
   ...
   'DeleteMarker': True,

在响应中。

A delete marker in Amazon S3 is a placeholder (or marker) for aversioned object that was named in a simple DELETE request. Becausethe object is in a versioning-enabled bucket, the object is notdeleted. But the delete marker makes Amazon S3 behave as if it isdeleted.

所以，基本上，您必须删除标记，然后删除文件。

If you want to delete a delete marker, it must have a version ID, andyou must specify that ID in a DELETE Object versionId request. If youuse a DELETE request to delete a delete marker (without specifying theversion ID of the delete marker), Amazon S3 does not delete the deletemarker, but instead, inserts another delete marker.

More on removing the delete marker

要删除删除标记和版本化文件，您可以使用以下代码:

警告!这将有效地清除您的存储桶!

def remove_versions(target_bucket: str) -> None:
    s3 = boto3.resource("s3", region_name="your_s3_bucket_region_goes_here")
    bucket = s3.Bucket(target_bucket)
    object_version_iterator = bucket.object_versions.all()

    for object_version in object_version_iterator:
        key = object_version.object_key
        object_id = object_version.id
        print(f"Deleting key: {key} with id: {object_id}")
        object_version.delete()

    print(f"Done. {target_bucket} has been purged.")
