我尝试使用Apache Camel + Amazon S3制作一个应用程序。这只是一个简单的例子，其中一个文件将被端点接收，并将被处理并发送到S3存储桶。

s3.bucket=my-bucket
camel.component.aws2-s3.access-key=${AWS_ACCESS_KEY_ID}
camel.component.aws2-s3.secret-key=${AWS_SECRET_ACCESS_KEY}
camel.component.aws2-s3.region=${AWS_REGION:us-east-2}

from("direct:s3")
        .log(INFO, log, "Sending to S3")
        .process(S3Processor())
        .to("aws2-s3://${properties.s3Bucket}?multiPartUpload=true&partSize=10485760")

字符串
当我给予我的用户S3：* 权限时，一切都很好。但我发现很难“微调”这些权限。每当我试图使用最低限度时，就像这样：

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": [
                "s3:PutObject",
                "s3:PutObjectAcl",
                "s3:ListBucket"
            ],
            "Resource": "arn:aws:s3:::*/*"
        }
    ]
}

启动应用程序时会出现S3错误：

我找不到任何地方列出我的用户应该拥有的最低权限。有人知道这些权限是什么吗？
啊，在任何人问之前，只要有s3：PutObject权限，我就可以使用aws命令行客户端将文件上传到我的bucket。
