你能不能把权限上载到S3文件？

Can you put permissions on files that are uploaded to S3?

或者，如果有人知道公会/ URL的文件，他们可以公开访问它？

Or if someone knows the guild/url to the file they can access it publicly?

如果是的，我们能建立什么样的权限？

If yes, what kind of permissions can we set?

推荐答案

权限是一个重要的机制来实现。你可以使内容可读为大家（无密码），或者需要密码。您可以通过生成一个密钥URI授予上传权限，您可以限制最大带宽。

Permissions are implemented with a key mechanism. You can make content readable for everyone (no password) or require a password. You grant upload privileges by generating a keyed URI which you can limit to a maximum bandwidth.
