Ruby on Rails AWS S3下载URL [英] Ruby on Rails AWS S3 Download URL

问题描述

如何为用户形成一个URL链接，以便当用户单击链接时，它会迫使他们下载AWS S3对象?

How can I form a url link for a user so that when the user clicks on the link, it forces them to download the AWS S3 object?

我已经看到了这两种解决方案:使用send_file从Amazon S3下载文件吗?，他们似乎引用了旧的AWS S3 v1 SDK，并且在v2 AWS S3中似乎没有url_for SDK.

I've seen these two solutions: Using send_file to download a file from Amazon S3? and Using send_file to download a file from Amazon S3? however, they seem to reference an old AWS S3 v1 SDK and there does not seem to be a url_for in the v2 AWS S3 SDK.

谢谢.

推荐答案

最后使用以下代码片段进行了解决.希望这对其他人有帮助.

Ended up using the following code snippet to solve. Hope this helps others.

presigner = Aws::S3::Presigner.new
    url = presigner.presigned_url(:get_object, #method
                    bucket: ENV['S3_BUCKET'], #name of the bucket
                    key: s3_key, #key name
                    expires_in: 7.days.to_i, #time should be in seconds
                    response_content_disposition: "attachment; filename=\"#{filename}\""
                    ).to_s
