我遵循这个答案的说明来生成以下S3桶策略:
{
"Id": "Policy1495981680273",
"Version": "2012-10-17",
"Statement": [
{
"Sid": "Stmt1495981517155",
"Action": [
"s3:GetObject"
],
"Effect": "Allow",
"Resource": "arn:aws:s3:::surplace-audio",
"Principal": "*"
}
]
}
我得到以下错误:
操作不适用于语句中的任何资源
我的保单中遗漏了什么?
当前回答
刚刚遇到了这个问题，并为那些想要在同一策略中拥有ListBucket和GetObject的人找到了一个更短的解决方案。重要的是在Resource下列出bucket-name和bucket-name/*。
{
"Id": "Policyxxxx961",
"Version": "2012-10-17",
"Statement": [
{
"Sid": "Stmtxxxxx4365",
"Action": [
"s3:GetObject",
"s3:ListBucket",
"s3:PutObject"
],
"Effect": "Allow",
"Resource": [
"arn:aws:s3:::bucket-name",
"arn:aws:s3:::bucket-name/*"
],
"Principal": "*"
}
]
}
其他回答
在我的案例中，这个错误的解决方案是试图删除我正在应用的一些动作。其中一些与此资源无关，或者不能使用此资源。 在这种情况下，它不让我包括这些:
GetBucketAcl ListBucket ListBucketMultipartUploads
错误操作不适用于语句中的任何资源
简单地说，这意味着您在策略中写入的操作不适用于资源。我试图公开我的存储桶，这样任何人都可以从我的存储桶中下载。我得到错误，直到我删除(“s3:ListBucket”)从我的声明。
{
"Id": "Policyxxxx961",
"Version": "2012-10-17",
"Statement": [
{
"Sid": "Stmtxxxxx4365",
"Action": [
"s3:GetObject",
"s3:ListBucket",
"s3:PutObject"
],
"Effect": "Allow",
"Resource": "arn:aws:s3:::bucket-name/*",
"Principal": "*"
}
]
}
因为列表桶不应用于桶内部，因此删除此操作策略可以很好地工作。
只需在json policy resource中做一个更改。
"Resource": ["arn:aws:s3:::bucket-name/*"]
注意:在bucket-name后面加/*
参考文档: https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements.html
来自IAM docs, http://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements.html#Action
有些服务不允许您为单个资源指定操作;相反，您在Action或NotAction元素中列出的任何操作都应用于该服务中的所有资源。在这些情况下，在Resource元素中使用通配符*。
有了这些信息，resource的值应该如下所示:
"Resource": "arn:aws:s3:::surplace-audio/*"
您还可以为每个文件夹配置ListBuckets，如下所示
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "AllowSESPuts-1521238702575",
"Effect": "Allow",
"Principal": {
"Service": "ses.amazonaws.com"
},
"Action": "s3:PutObject",
"Resource": "arn:aws:s3:::buckets.email/*",
"Condition": {
"StringEquals": {
"aws:Referer": "[red]"
}
}
},
{
"Sid": "Stmt1586754972129",
"Effect": "Allow",
"Principal": {
"AWS": "arn:aws:iam::596322993031:user/[red]"
},
"Action": "s3:ListBucket",
"Resource": "arn:aws:s3:::buckets.email",
"Condition": {
"StringEquals": {
"s3:delimiter": "/",
"s3:prefix": [
"",
"domain.co",
"domain.co/user"
]
}
}
},
{
"Sid": "Stmt1586754972129",
"Effect": "Allow",
"Principal": {
"AWS": "arn:aws:iam::596322993031:user/[red]"
},
"Action": "s3:ListBucket",
"Resource": "arn:aws:s3:::buckets.email",
"Condition": {
"StringLike": {
"s3:prefix": "domain.co/user/*"
}
}
},
{
"Effect": "Allow",
"Principal": {
"AWS": "arn:aws:iam::596322993031:user/[red]"
},
"Action": [
"s3:GetObject",
"s3:PutObject",
"s3:DeleteObject"
],
"Resource": "arn:aws:s3:::buckets.email/domain.co/user/*"
}
]
}
这些规则与SES一起用于接收电子邮件，但允许外部用户查看SES放入bucket中的文件。 我按照这里的说明做了:https://aws.amazon.com/blogs/security/writing-iam-policies-grant-access-to-user-specific-folders-in-an-amazon-s3-bucket/
此外，必须将prefix指定为域。co/user/ WITH在使用SDK时，否则你将被拒绝访问。希望能对大家有所帮助
