Listado de contenidos de un cubo con boto3
¿Cómo puedo ver lo que hay dentro de un cubo en S3 con boto3
? (es decir, hacer un "ls"
)?
Haciendo lo siguiente:
import boto3
s3 = boto3.resource('s3')
my_bucket = s3.Bucket('some/path/')
Devuelve:
s3.Bucket(name='some/path/')
¿Cómo veo su contenido?

Una forma de ver el contenido sería:
for object in my_bucket.objects.all():
print(object)

Esto es similar a un 'ls' pero no tiene en cuenta la convención de la carpeta de prefijos y listará los objetos en el cubo. Queda en manos del lector filtrar los prefijos que forman parte del nombre de la clave.
En Python 2:
from boto.s3.connection import S3Connection
conn = S3Connection() # assumes boto.cfg setup
bucket = conn.get_bucket('bucket_name')
for obj in bucket.get_all_keys():
print(obj.key)
En Python 3:
from boto3 import client
conn = client('s3') # again assumes boto.cfg setup, assume AWS S3
for key in conn.list_objects(Bucket='bucket_name')['Contents']:
print(key['Key'])

Si desea pasar las claves de ACCESO y SECRETO:
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')
your_bucket = s3.Bucket('your_bucket')
for s3_file in your_bucket.objects.all():
print(s3_file.key)

Asumo que ha configurado la autenticación por separado.
import boto3
s3 = boto3.resource('s3')
my_bucket = s3.Bucket('bucket_name')
for awsfile in my_bucket.objects.all():
print file.key

Una forma más parsimoniosa, en lugar de iterar a través de un bucle for, también podría imprimir el objeto original que contiene todos los archivos dentro de su bucket S3:
session = Session(aws_access_key_id=aws_access_key_id,aws_secret_access_key=aws_secret_access_key)
s3 = session.resource('s3')
bucket = s3.Bucket('bucket_name')
files_in_s3 = bucket.objects.all()
#you can print this iterable with print(list(files_in_s3))

Lo hice así, incluyendo el método de autenticación:
s3_client = boto3.client(
's3',
aws_access_key_id='access_key',
aws_secret_access_key='access_key_secret',
config=boto3.session.Config(signature_version='s3v4'),
region_name='region'
)
response = s3_client.list_objects(Bucket='bucket_name', Prefix=key)
if ('Contents' in response):
# Object / key exists!
return True
else:
# Object / key DOES NOT exist!
return False
