Use boto3 to download from public bucket

问题

I'm trying to list files from a public bucket on AWS but the best I got was list my own bucket and my own files. I'm assuming that boto3 is using my credentials configured in the system to list my things.

How can I force it to list from a specific bucket, rather than my own bucket?

#http://sentinel-s2-l1c.s3-website.eu-central-1.amazonaws.com/
g_bucket = "sentinel-s2-l1c"
g_zone = "eu-central-1"

Thank you for helping me out.

回答1:

Pass the region_name when creating the client

s3client = boto3.client('s3', region_name='eu-central-1')

Then list objects from the bucket

objects = s3client.list_objects(Bucket='sentinel-s2-l1c')
