You can also use the following (boto.s3.connect_to_region):
您还可以使用以下内容 (boto.s3.connect_to_region)：
import boto
from boto.s3.key import Key
import boto.s3.connection
AWS_ACCESS_KEY_ID = '<access key>'
AWS_SECRET_ACCESS_KEY = '<my secret key>'
Bucketname = 'Bucket-name'
conn = boto.s3.connect_to_region('ap-southeast-1',
aws_access_key_id=AWS_ACCESS_KEY_ID,
aws_secret_access_key=AWS_SECRET_ACCESS_KEY,
is_secure=True, # uncomment if you are not using ssl
calling_format = boto.s3.connection.OrdinaryCallingFormat(),
)
bucket = conn.get_bucket(Bucketname)
This way you don't have to care about the 'exact' endpoint with the full hostname. And yes like @garnaat mentioned, use the latest boto API.
这样您就不必关心具有完整主机名的“确切”端点。是的，就像@garnaat 提到的那样，使用最新的 boto API。

The request to the host s3.ap-southeast-1.amazonaws.comis failing. I also cannot resolve it from my end. Check your bucket settings for the correct host.
对主机的请求s3.ap-southeast-1.amazonaws.com失败。我也无法从我的角度解决它。检查正确主机的存储桶设置。
There might also be a problem with your internet connection or the DNS server. Try pinging the host manually from command line and see if it resolves. Alternatively, try using a different DNS.
您的互联网连接或 DNS 服务器也可能有问题。尝试从命令行手动 ping 主机，看看它是否解决。或者，尝试使用不同的 DNS。
Edit: Quick googling suggests that the host might be s3-ap-southeast-1.amazonaws.com.
编辑：快速谷歌搜索表明主机可能是s3-ap-southeast-1.amazonaws.com.

There is a typo in the host parameter. The right one is: s3-ap-southeast-1.amazonaws.com
主机参数中有一个错字。正确的是：s3-ap-southeast-1.amazonaws.com

Gotcha: capture traffic on your Ethernet link and ensure CNAME in DNS queries do NOTcontain '\r' character e.g. in the bucket name.
陷阱：捕获以太网链路上的流量并确保 DNS 查询中的 CNAME不包含 '\r' 字符，例如在存储桶名称中。

from boto3.session import Session
ACCESS_KEY='your_access_key'
SECRET_KEY='your_secret_key'
session = Session(aws_access_key_id=ACCESS_KEY,aws_secret_access_key=SECRET_KEY)
s3 = session.resource('s3')
my_bucket = s3.Bucket('bucket_name')
for s3_file in my_bucket.objects.all():
print(s3_file.key)
