S3-无法使用Root账户将某些文件夹公开。

您可以尝试使用针对对象(S3 bucket)的Bucket策略来控制文件夹的公开性。以下是示例代码：

{ "Version": "2012-10-17", "Statement": [ { "Sid": "FolderPermissions", "Effect": "Allow", "Principal": "", "Action": [ "s3:GetObject" ], "Resource": [ "arn:aws:s3:::bucket-name/folder-name/" ] }, { "Sid": "BlockPublicAccess", "Effect": "Deny", "Principal": "", "Action": [ "s3:PutObject", "s3:PutObjectAcl" ], "Resource": [ "arn:aws:s3:::bucket-name/folder-name/" ], "Condition": { "Bool": { "aws:SecureTransport": "false" } } } ] }

上述代码块允许获取一个名为'folder-name”的文件夹，同时不允许针对该文件夹进行公开操作。您可以将Bucket策略设置为符合您的需求。
