how to get boto working with s3proxy (with GCS on the backend)

boto_download.py

#!/usr/bin/python

from boto import connect_s3
from boto.s3.connection import OrdinaryCallingFormat
from boto.s3.key import Key

import sys

s3 = connect_s3(aws_access_key_id = 'access',
    aws_secret_access_key = 'secret',
    host = '127.0.0.1', port = 7000, is_secure = False,
    calling_format = OrdinaryCallingFormat())

bucket_name = 'dabucket'

bucket = s3.get_bucket(bucket_name)

filename = "%s" % sys.argv[1]

print 'Downloading %s from Amazon S3 bucket %s' % (filename, bucket_name)

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

k = Key(bucket)
k.key = filename
k.get_contents_to_file(open(filename, 'w'), cb=percent_cb, num_cb=10)

boto_upload.py

#!/usr/bin/python

from boto import connect_s3
from boto.s3.connection import OrdinaryCallingFormat
from boto.s3.key import Key

import sys

s3 = connect_s3(aws_access_key_id = 'access',
    aws_secret_access_key = 'secret',
    host = '127.0.0.1', port = 7000, is_secure = False,
    calling_format = OrdinaryCallingFormat())

bucket_name = 'dabucket'

bucket = s3.get_bucket(bucket_name)

filename = "%s" % sys.argv[1]
print 'Uploading %s to Amazon S3 bucket %s' % (filename, bucket_name)

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

k = Key(bucket)
k.key = filename
k.set_contents_from_filename(filename, cb=percent_cb, num_cb=10)
