python - 使用 boto3 连接到 S3 兼容存储

Question

我正在努力让 boto3 连接到 S3 兼容资源，我似乎无法在 boto3 页面上找到一个像样的例子，所以我的尝试如下(取自 https://docs.oracle.com/cd/E91275_01/html/E96223/gsyqi.html)

我得到了回溯(下面的完整输出)AttributeError: 'str' 对象没有属性 'get'

import logging
import boto3
from mycreds.creds import Mycreds

# Pull in my config
access_key = Mycreds.access_key
secret_key = Mycreds.secret_key
endpoint = Mycreds.endpoint

b3_session = boto3.Session(aws_access_key_id=access_key,
                           aws_secret_access_key=secret_key,
                           region_name='us-east-1')

b3_client = b3_session.client('s3', endpoint_url=endpoint)

bucket = b3_client.create_bucket(Bucket='somenewbucket')

回溯:

Answer 1

以防万一其他人遇到同样的问题，我最终将其追踪到 ~/.aws/config 文件，一旦我删除它就解决了问题。

不幸的是，我应该移动而不是删除文件，所以我无法进一步诊断它。
