适用于所有存储桶的 Amazon S3 缓存控制 [英] Amazon S3 Cache-Control for all bucket

问题描述

我使用 Amazon S3 和 CloudFront.我有静态图片，用户下载图片(每小时 + 100 张图片).

I use Amazon S3 and CloudFront. I have static images and users downloaded images(every hour + 100 images).

我需要为所有存储桶设置 Cache-Control http 标头.

I need to set Cache-Control http header for all bucket.

我在谷歌搜索，但找不到任何说明，如何执行此操作.

I search in google, but I cant find any instruction, how to do this.

是的，我知道文件属性中的 MetaData，但我需要所有存储桶的 MetaData(+ 未来的新文件).

Yes, I know about MetaData in file Properties, but I need MetaData for all bucket (+ new files in future).

如果在亚马逊控制台无法做到，有没有开源的解决方案?

If it is not possible to do in Amazon console, is there any open source solutions?

谢谢！

推荐答案

S3 没有在现有或未来对象上设置全局存储桶元数据的机制.您的代码需要在创建对象时设置此项.

S3 does not have a mechanism for setting global bucket metadata on existing or future objects. Your code needs to set this when the objects are created.

您可以使用放置/复制"将其添加到现有对象中.API 的操作，允许您使用修改后的元数据将对象复制到自身上，而无需实际下载和重新上传对象.

You can add it to existing objects using the "put/copy" operation of the API, which allows you to copy an object onto itself, with modified metadata, without actually downloading and re-uploading the object.

关于开源解决方案，可能有，但他们可以使用的唯一可能机制是执行相同的操作 - 遍历存储桶并通过 API 更新每个对象的元数据.不过无论如何:

Regarding open-source solutions, there might be, but the only possible mechanism they could use would be to perform the same actions -- iterating through the bucket and updating each object's metadata via the API. In any event, though:
