如何打印可用的桶？

Question

I'm trying to print available buckets on AWS but failed. I tried multiple tutorials online and i would get cannot locate credentials and 's3.ServiceResource' object has no attribute errors.

s3 = boto3.resource('s3',aws_access_key_id = "Random",aws_secret_access_key = "Secret" )
client = s3.client('s3')
response = client.list_buckets()
print(response)

Answer 1

Can you try:

for bucket in s3.buckets.all():

   print(bucket.name)

Answer 2

The problem is probably because you are defining s3 as a resource:

s3 = boto3.resource('s3')

But then you are trying to use it as a client:

client = s3.client('s3')

That won't work. If you want a client, create one with:

s3_client = boto3.client('s3')

Or, you can extract a client from the resource:

s3_resource = boto3.resource('s3')
response = s3_resource.meta.client.list_buckets()

Or, sticking with the resource, you can use:

s3_resource = boto3.resource('s3')
for bucket in s3_resource.buckets.all():
  # Do something with bucket

Confused? Try to stick with one method. Client directly matches the underlying API calls made to S3 and is the same as all other languages. Resource is a more "Pythonic" way of accessing resources. The calls get translated to client API calls. Resources can be a little more challenging when figuring out required permissions, since there isn't a one-to-one mapping to actual API call.
