尝试从文档中找出,但无法创建可以访问 s3 存储桶的联合用户
首先是进口
>>> from boto.s3.connection import S3Connection
>>> from boto.sts import STSConnection
然后在s3中创建一个bucket
>>> s3c = ('access key', 'secret key')
>>> s3c.create_bucket('ranjith_new_bucket')
然后创建一个联合用户,如果我理解正确的话,这是一种创建临时凭据的方法
>>> sts = STSConnection('access key', 'secret key')
>>> user = sts.get_federation_token('guest_user_1')
但是,当我尝试获取所有可访问存储桶的列表时,出现错误。
>>> s3c2 = S3Connection(user.credentials.access_key, user.credentials.secret_key)
>>> s3c2.get_all_buckets()

文档说我必须提供一个策略字符串,但是文档很难消化。我知道我必须在某处定义一个策略并在创建联合用户时使用它,但不确定在哪里或如何做到这一点。
我确实试过这个:
permission = {
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": ["sts:GetFederationToken"],
"Resource": "*"
},
{
"Effect": "Allow",
"Action": ["s3:*"],
"Resource": "arn:aws:s3:::mybucket/ranjith_new_bucket/*"
}
]
}
sts.get_federation_token('some_other_user', json.dumps(permission))

这真的很愚蠢,因为我所做的只是放入策略的 json 转储中。我什至无法找到该问题的任何在线资源。
如果有人可以指导我,以便我最终创建一个可以访问ranjith_new_bucket
上面创建的联合用户,那就太好了。代码片段将不胜感激。
