Boto kullanarak S3 klasöründeki dizine dosya nasıl yüklenir

Python kullanarak s3 kovasındaki bir dosyayı kopyalamak istiyorum.

Ör: Grup adı = testim var. Ve pakette, "döküm" ve "giriş" adlarında 2 klasörüm var. Şimdi python kullanarak yerel dizinden S3 "döküm" klasörüne bir dosya kopyalamak istiyorum ... Biri bana yardımcı olabilir mi?

Bunu dene...

import boto
import boto.s3
import sys
from boto.s3.key import Key

AWS_ACCESS_KEY_ID = ''
AWS_SECRET_ACCESS_KEY = ''

bucket_name = AWS_ACCESS_KEY_ID.lower() + '-dump'
conn = boto.connect_s3(AWS_ACCESS_KEY_ID,
        AWS_SECRET_ACCESS_KEY)


bucket = conn.create_bucket(bucket_name,
    location=boto.s3.connection.Location.DEFAULT)

testfile = "replace this with an actual filename"
print 'Uploading %s to Amazon S3 bucket %s' % \
   (testfile, bucket_name)

def percent_cb(complete, total):
    sys.stdout.write('.')
    sys.stdout.flush()


k = Key(bucket)
k.key = 'my test file'
k.set_contents_from_filename(testfile,
    cb=percent_cb, num_cb=10)

[GÜNCELLEME] Ben bir pythonist değilim, bu yüzden içe aktarma ifadeleriyle ilgili uyarılar için teşekkürler. Ayrıca, kimlik bilgilerini kendi kaynak kodunuzun içine yerleştirmenizi önermem. Bunu AWS içinde çalıştırıyorsanız, Örnek Profilleriyle IAM Kimlik Bilgilerini kullanın ( http://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use_switch-role-ec2_instance-profiles.html ) ve aynı davranışı Geliştirme / Test ortamınız, AdRoll'dan Hologram gibi bir şey kullanın ( https://github.com/AdRoll/hologram )

Bu kadar karmaşık hale getirmeye gerek yok:

s3_connection = boto.connect_s3()
bucket = s3_connection.get_bucket('your bucket name')
key = boto.s3.key.Key(bucket, 'some_file.zip')
with open('some_file.zip') as f:
    key.send_file(f)

import boto3

s3 = boto3.resource('s3')
BUCKET = "test"

s3.Bucket(BUCKET).upload_file("your/local/file", "dump/file")

Bunu kullandım ve uygulaması çok basit

import tinys3

conn = tinys3.Connection('S3_ACCESS_KEY','S3_SECRET_KEY',tls=True)

f = open('some_file.zip','rb')
conn.upload('some_file.zip',f,'my_bucket')

https://www.smore.com/labs/tinys3/

from boto3.s3.transfer import S3Transfer
import boto3
#have all the variables populated which are required below
client = boto3.client('s3', aws_access_key_id=access_key,aws_secret_access_key=secret_key)
transfer = S3Transfer(client)
transfer.upload_file(filepath, bucket_name, folder_name+"/"+filename)

Kimlik bilgileriyle bir oturumda s3'e dosya yükleyin.

import boto3

session = boto3.Session(
    aws_access_key_id='AWS_ACCESS_KEY_ID',
    aws_secret_access_key='AWS_SECRET_ACCESS_KEY',
)
s3 = session.resource('s3')
# Filename - File to upload
# Bucket - Bucket to upload to (the top level directory under AWS S3)
# Key - S3 object name (can contain subdirectories). If not specified then file_name is used
s3.meta.client.upload_file(Filename='input_file_path', Bucket='bucket_name', Key='s3_output_key')

Bu da işe yarayacak:

import os 
import boto
import boto.s3.connection
from boto.s3.key import Key

try:

    conn = boto.s3.connect_to_region('us-east-1',
    aws_access_key_id = 'AWS-Access-Key',
    aws_secret_access_key = 'AWS-Secrete-Key',
    # host = 's3-website-us-east-1.amazonaws.com',
    # is_secure=True,               # uncomment if you are not using ssl
    calling_format = boto.s3.connection.OrdinaryCallingFormat(),
    )

    bucket = conn.get_bucket('YourBucketName')
    key_name = 'FileToUpload'
    path = 'images/holiday' #Directory Under which file should get upload
    full_key_name = os.path.join(path, key_name)
    k = bucket.new_key(full_key_name)
    k.set_contents_from_filename(key_name)

except Exception,e:
    print str(e)
    print "error"   

Bu üç astarlıdır. Sadece boto3 belgelerindeki talimatları takip edin .

import boto3
s3 = boto3.resource(service_name = 's3')
s3.meta.client.upload_file(Filename = 'C:/foo/bar/baz.filetype', Bucket = 'yourbucketname', Key = 'baz.filetype')

Bana biraz daha düzeni varmış gibi görünen bir şeyim var:

import boto3
from pprint import pprint
from botocore.exceptions import NoCredentialsError


class S3(object):
    BUCKET = "test"
    connection = None

    def __init__(self):
        try:
            vars = get_s3_credentials("aws")
            self.connection = boto3.resource('s3', 'aws_access_key_id',
                                             'aws_secret_access_key')
        except(Exception) as error:
            print(error)
            self.connection = None


    def upload_file(self, file_to_upload_path, file_name):
        if file_to_upload is None or file_name is None: return False
        try:
            pprint(file_to_upload)
            file_name = "your-folder-inside-s3/{0}".format(file_name)
            self.connection.Bucket(self.BUCKET).upload_file(file_to_upload_path, 
                                                                      file_name)
            print("Upload Successful")
            return True

        except FileNotFoundError:
            print("The file was not found")
            return False

        except NoCredentialsError:
            print("Credentials not available")
            return False

Burada üç önemli değişken vardır, BUCKET sabiti , file_to_upload ve file_name

BUCKET: S3 klasörünüzün adıdır

file_to_upload_path: yüklemek istediğiniz dosyanın yolu olmalıdır

file_name: paketinizde ortaya çıkan dosya ve yoldur (bu, klasörleri veya ne olursa olsun eklediğiniz yerdir)

Pek çok yol var, ancak bu kodu bunun gibi başka bir komut dosyasında yeniden kullanabilirsiniz

import S3

def some_function():
    S3.S3().upload_file(path_to_file, final_file_name)
