Question

所以我试图在特定的s3存储桶中创建一个新的密钥作为字符串文件，但是我遇到了这个特殊的错误。我需要能够使用k.set_contents_from_string方法，因为稍后我打算从指定的URL直接将图像下载到s3存储桶（本地不这样做）。 P.S：连接到s3的凭据存储在.aws凭证文件中，以便正确进行身份验证。

代码：

import boto3
from boto.s3.key import Key
import urllib3
import boto

#s3 = boto3.resource('s3')
#mybucket = s3.Bucket("bucket_name")
#mybucket
c = boto.connect_s3()
b = c.get_bucket("bucket_name")
k = Key(c)
k.key = 'foobar'
k.set_contents_from_string('This is a test of S3')

错误：

    AttributeError: 'HTTPSConnection' object has no attribute 'provider'

Answer 1

您的第k = Key(c)行应为k = Key(b)，因为Key需要一个存储桶作为其构造函数参数

'HTTPSConnection'对象没有属性'provider'
