Question

我创建了一个名为 Test_User 的用户，并为其分配了直接策略，该策略包含对所有 S3 存储桶的访问级别权限，但仅取消选中 DELETEOBJECT 政策，因为我不希望用户删除存储桶中的对象。

现在的问题是，即使我在 WRITE 部分中未特别选中 DELETEOBJECT ， Test_User 仍可以删除任何存储桶中的对象

为什么？

如何允许s3：*然后拒绝s3：deleteObject，拒绝覆盖任何allow语句。

但这不是最佳实践，实际上，您应该明确分配角色，并且仅在默认情况下禁用所有需要的内容。

为什么即使用户的策略未选中DELETEOBJECT属性，用户仍然可以从S3存储桶中删除对象？
