如何使用 AWS SDK 从 S3 下载对象 - RESTful

Question

I'm looking for a programmatic way to download images from an S3 bucket to my computer.

I tried " Using send_file to download a file from Amazon S3? " but it just redirected me to a link that only shows my PDF object.

This is my download function using the AWS documentation :

s3 = Aws::S3::Resource.new(region: 'us-east-2')
obj = s3.bucket('bucket').object('image')
obj.get(response_target: '~/')

and this is my download code from linked:

data = open("https://#{bucket}.s3.amazonaws.com/#{filepath}")
send_data data.read, filename: "file.pdf", type: "application/pdf", disposition: 'inline', stream: 'true', buffer_size: '4096'

obj.get is what is confusing: I want to download it to my computer, not my codebase.

Some say that a download link is just the image link from my bucket if it is set to public, which it is. What's this about?

Final solution: Change the disposition to 'attachment'

data = open("https://#{bucket}.s3.amazonaws.com/#{filepath}")
send_data data.read, filename: "file.pdf", type: "application/pdf", disposition: 'attachment', stream: 'true', buffer_size: '4096'

Answer 1

If you change the disposition to attachment the browser download the file?

This may be related to content-disposition inline value.
