“请求已过期"；将S3与Active Storage一起使用时

问题描述

我第一次使用ActiveStorage.在开发过程中一切正常，但在生产中(Heroku)，我的图像无故消失了.

I'm using ActiveStorage for the first time.Everything works fine in development but in production (Heroku) my images disappear without a reason.

他们第一次显示正常，但现在没有图像显示.在控制台中，我可以看到此错误:

They were showing ok the first time, but now no image is displayed. In the console I can see this error:

GET https://XXX.s3.amazonaws.com/variants/Q7MZrLyoKKmQFFwMMw9tQhPW/XXX 403 (Forbidden)

如果我尝试直接访问该URL，我会得到一个XML

If I try to visit that URL directly I get an XML

<Error>
  <Code>AccessDenied</Code>
  <Message>Request has expired</Message>
  <X-Amz-Expires>300</X-Amz-Expires>
  <Expires>2018-07-24T13:48:25Z</Expires>
  <ServerTime>2018-07-24T15:25:37Z</ServerTime>
  <RequestId>291D41FAC6708334</RequestId>      
  <HostId>lEVGuwA6Hvlm/i40PeXaje9SEBYks9+uk6DvBs=</HostId>
</Error>

这就是我的看法

<div class="cover" style="background-image: url('<%= rails_representation_path(experience.thumbnail) %>')"></div>

这就是我模型中的东西

def thumbnail
  self.cover.variant(resize: "300x300").processed
end

用简单的话来说，我不希望图像过期但要一直存在.

In simple words, I don't want images to expire but to be always there.

谢谢

推荐答案

ActiveStorage不支持未过期的链接.它使用到期链接(私有)，并且仅支持在服务上以私有形式上载文件.

ActiveStorage does not support non-expiring link. It uses expiring links (private), and support uploading files only as private on your service.

这对我来说也是一个问题，仅对S3做2个补丁(警告)，一个简单的〜30行，它覆盖ActiveStorage以仅与未到期的(公共)链接配合使用，并且另一个为has_one_attached和has_many_attached方法添加acl选项的.

It was a problem for me too, and did 2 patches (caution) for S3 only, one simple ~30lines that override ActiveStorage to work only with non-expiring (public) links, and another that add an acl option to has_one_attached and has_many_attached methods.

希望有帮助.
