How to upload a file to directory in S3 bucket using boto

Question

I want to copy a file in the s3 bucket using python.

Ex: I have a bucket name = test. And in the bucket, I have 2 folders named "dump" & "input". Now I want to copy a file from local directory to S3 "dump" folder using python... Can anyone help me?

Try this code:

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)
