import boto.s3.connection
# 账户
access_key = 'xxxx'
secret_key = 'xxxx'
#创建连接
conn = boto.connect_s3(
        aws_access_key_id = access_key,
        aws_secret_access_key = secret_key,
        host = '10.0.0.xxx',
        port = xxxx,
        is_secure=False,               # uncomment if you are not using ssl
        calling_format = boto.s3.connection.OrdinaryCallingFormat(),
        )

列出拥有的桶

for bucket in conn.get_all_buckets():
        print "{name}t{created}".format(
                name = bucket.name,
                created = bucket.creation_date,
        )

创建一个桶

bucket = conn.create_bucket('my-new-bucket')

列出存储桶的内容

for key in bucket.list():
        print "{name}t{size}t{modified}".format(
                name = key.name,
                size = key.size,
                modified = key.last_modified,
                )

删除桶
笔记： 桶必须是空的！否则就不行了！

conn.delete_bucket(bucket.name)

创建对象

key = bucket.new_key('hello.txt')
key.set_contents_from_string('Hello World!')

更改对象的 ACL

hello_key = bucket.get_key('hello.txt')
hello_key.set_canned_acl('public-read')
plans_key = bucket.get_key('secret_plans.txt')
plans_key.set_canned_acl('private')

下载对象（到文件）

key = bucket.get_key('perl_poetry.pdf')
key.get_contents_to_filename('/home/larry/documents/perl_poetry.pdf')

删除对象

bucket.delete_key('goodbye.txt')

生成对象下载 URL（签名和未签名）

hello_key = bucket.get_key('hello.txt')
hello_url = hello_key.generate_url(0, query_auth=False, force_http=True)
print hello_url

plans_key = bucket.get_key('secret_plans.txt')
plans_url = plans_key.generate_url(3600, query_auth=True, force_http=True)
print plans_url
