amazon-s3 - Boto 无法使用 S3 IAM 角色进行身份验证

Question

我有一个名为 Role1 的角色。该角色应用了以下策略。

我有一个 IAM 角色为 Role1 的 ec2 实例。

当我尝试 conn.get_bucket('fooo_udata') 时，我返回了 403 错误。

对此有什么想法吗？

  {
"Statement": [
{
  "Effect": "Allow",
  "Action": ["s3:ListAllMyBuckets"],
  "Resource": "arn:aws:s3:::*"
},
{
  "Effect": "Allow",
  "Action": ["s3:ListBucket","s3:GetBucketLocation","s3:*"],
  "Resource": ["arn:aws:s3:::fooo_uadata/","arn:aws:s3:::fooo_uadata/*"]
},
{
  "Effect": "Allow",
  "Action": ["s3:PutObject","s3:GetObject","s3:DeleteObject"],
  "Resource":   ["arn:aws:s3:::fooo_uadata/","arn:aws:s3:::fooo_uadata/*"]
}
]
}

Answer 1

我认为您不想在存储桶策略中包含“/”字符。所以，尝试改变:

{
  "Effect": "Allow",
  "Action": ["s3:ListBucket","s3:GetBucketLocation","s3:*"],
  "Resource": ["arn:aws:s3:::fooo_uadata/","arn:aws:s3:::fooo_uadata/*"]
},

对此:

{
  "Effect": "Allow",
  "Action": ["s3:ListBucket","s3:GetBucketLocation","s3:*"],
  "Resource": ["arn:aws:s3:::fooo_uadata","arn:aws:s3:::fooo_uadata*"]
},

因为您的存储桶的名称是 foo_uadata 而不是 foo_uadata/。
