我正在尝试从python boto转移到较新的boto3模块,以便在Amazon S3上操作文件。
我还需要使用Amazon IAM角色,就像我使用旧的boto模块一样。我不确定如何在服务器上设置IAM角色,但我所要做的就是:
s3_conn = S3Connection()
我可以访问服务器可以访问的所有存储桶。
这在boto3中似乎有所不同:
s3 = boto3.resource('s3')
for bucket in s3.buckets.all():
print(bucket.name)
我收到错误:
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.7/dist-packages/boto3/resources/collection.py", line 83, in __iter__
for page in self.pages():

pages = [getattr(client, self._py_operation_name)(**params)]

我正在浏览boto3文档,但我不确定如何设置IAM角色:
