Add Tag while uploading an object to Amazon s3 in rails

问题

I'm trying to upload CSV files to Amazon S3.

I'm able to add metadata using the below code snippet:

s3_obj.upload_file(file_to_be_uploaded, {"content_type": "application/octet-stream"}

How can I add suitable tags (key-value pairs) -- for example exp: tag = { marked_to_delete: "true" } -- while uploading?

回答1:

You should be able to do that by passing tagging: "marked_to_delete=true" as an option.

Options are passed to an instance of AWS::S3::Client's put_object method. The docs give a similar example:

resp = client.put_object({
  body: "filetoupload", 
  bucket: "examplebucket", 
  key: "exampleobject", 
  server_side_encryption: "AES256", 
  tagging: "key1=value1&key2=value2", 
})
