使用 boto python 从 s3 递归下载文件. [英] Downloading the files from s3 recursively using boto python.

问题描述

我在 s3 中有一个存储桶，它有很深的目录结构.我希望我可以一次下载它们.我的文件看起来像这样:

I have a bucket in s3, which has deep directory structure. I wish I could download them all at once. My files look like this :

foo/bar/1. . 
foo/bar/100 . . 

有什么方法可以使用python中的boto lib从s3存储桶中递归下载这些文件?

Are there any ways to download these files recursively from the s3 bucket using boto lib in python?

提前致谢.

推荐答案

您可以像这样下载存储桶中的所有文件(未经测试):

You can download all files in a bucket like this (untested):

from boto.s3.connection import S3Connection

conn = S3Connection('your-access-key','your-secret-key')
bucket = conn.get_bucket('bucket')
for key in bucket.list():
    try:
        res = key.get_contents_to_filename(key.name)
    except:
        logging.info(key.name+":"+"FAILED")

请记住，S3 中的文件夹只是编写密钥名称的另一种方式，只有客户端才会将其显示为文件夹.

Keep in mind that folders in S3 are simply another way of writing the key name and only clients will show this as folders.
