使用boto3从AWS S3存储桶下载特定文件

Question

I am trying to download to a local machine specific files from an S3 bucket. The Bucket structure is as follow:

BucketName/TT/2019/07/23/files.pdf

I want to download all files under:

BucketName/TT/2019/07/23

How can this be done?

Answer 1

Please try this:

import boto3
s3 = boto3.resource('s3')
bucket = s3.Bucket('BucketName')

for obj in bucket.objects.filter(Prefix='TT/2019/07/23/'):
    filename = obj.key.split("/").pop()
    if filename != "":
        print('Downloading ', obj.key)
        bucket.download_file(obj.key, filename)

Note that you will need to configure aws first by setting up authentication credentials. Please refer to the quick start guide to see how to do that.
