我只想下載一張圖片。然后上傳到Amazon S3。但它不起作用。在'builtin_function_or_method' object has no attribute 'StringIO'

Traceback (most recent call last):

File "flickrDump.py", line 16, in

imgpath = s3.upload_thumbnail(thumbnail_name=tools.randomString(10), thumbnail_data=tdata,bucket="fabletest")

File "../lib/s3.py", line 52, in upload_thumbnail

k.set_contents_from_string(thumbnail_data)

return self.bucket.connection.make_request('PUT', self.bucket.name,

AttributeError: 'str' object has no attribute 'connection'

我下載和上傳的代碼是：

^{pr2}$

我使用的庫是s3庫。我在某個地方下載的，所以應該是標準的。在from boto.s3.connection import S3Connection

from boto.s3.key import Key

from boto.s3.bucket import Bucket

import datetime

ACCESSKEY = 'MYKEY'

SECRETKEY = 'MYSECRET'

def get_bucket_path(bucket,filename,https=False):

path = None

if isinstance(bucket, Bucket):

path = bucket.name

else:

path = bucket

if https:

return "https://s3.amazonaws.com/%s/%s" % (path, filename)

else:

return "http://s3.amazonaws.com/%s/%s" % (path, filename)

def _aws_keys():

return ACCESSKEY, SECRETKEY

def _conn():

key,secret = _aws_keys()

return S3Connection(key,secret)

def cache_bucket(conn = _conn()):

bucket = conn.create_bucket('mimvicache') bucket.make_public()

return bucket

class AwsException(Exception):

def __init__(self,value):

self.errorval = value

def __str__(self):

return repr(self.errorval)

def upload_thumbnail(thumbnail_name,thumbnail_data=None,thumbnail_path=None,bucket=cache_bucket

(),conn=_conn(),notes=None,image_id=None):

k = Key(bucket)

k.key = thumbnail_name

if notes is not None:

k.set_metadata("notes",notes)

if image_id is not None:

k.set_metadata("image_id",image_id)

if thumbnail_data is not None:

k.set_contents_from_string(thumbnail_data)

elif thumbnail_path is not None:

k.set_contents_from_filename(thumbnail_path)

else:

raise AwsException("No file name")

k.set_acl('public-read')

return get_bucket_path(bucket.name,k.key)

有人能幫我把這個圖片上傳到S3嗎？在
