如何使用python boto获取Amazon S3中仅文件夹的列表? [英] How can I get the list of only folders in amazon S3 using python boto?

问题描述

我正在使用boto，python和Amazon s3.

I am using boto and python and amazon s3.

如果我使用

[列表中的键的键名(self.bucket.list())]

然后我获得了所有文件的所有密钥.

then I get all the keys of all the files.

mybucket/files/pdf/abc.pdf
mybucket/files/pdf/abc2.pdf
mybucket/files/pdf/abc3.pdf
mybucket/files/pdf/abc4.pdf
mybucket/files/pdf/new/
mybucket/files/pdf/new/abc.pdf
mybucket/files/pdf/2011/

什么是最好的方法

1. either get all folders from s3
2. or from that list just remove the file from the last and get the unique keys of folders

我正在考虑这样做

set([re.sub("/[^/]*$","/",path) for path in mylist]

推荐答案

基于sethwm的答案:

building on sethwm's answer:

要获取顶层目录:

list(bucket.list("", "/"))

要获取文件的子目录:

list(bucket.list("files/", "/")

以此类推.
