The getFile example downloads and object from S3 and "sinks" its contents to a file. To integrate with an existing program that's using S3 URIs, you can build it with the bucket and key:

s3Uri :: BucketName -> ObjectKey -> Text

s3Uri (BucketName bn) (ObjectKey ok) = "s3://" <> bn <> "/" <> ok

There are also presigned S3 URLs (also in the examples file), but those are for HTTP requests, not aws cli requests.

Using turtle with with aws cli is great - nice light way to get AWS functionality without going pulling in amazonka.

Question: How can I generate an S3://absolute/url from an Object (https://hackage.haskell.org/package/amazonka-s3-1.4.5/docs/Network-AWS-S3-Types.html#t:Object)?

Context: I've been using turtle to call "aws s3 ls" and I'm trying to figure out how to replace that with amazonka. Absolute s3 urls were central to how my program worked. I KNow how to get objects now and filter them, but I don't know how to convert an object to an S3 url to integrate with my existing program.

I came across the getFile function (https://github.com/brendanhay/amazonka/blob/4fdd746346323aac7de6e82752b16609ef0bf212/examples/src/Example/S3.hs#L65) and tried downloading a file from s3.

Perhaps I had something wrong, but it didn't seem like just the S3 Bucket and S3 Object key were enough to download a given file. If I'm wrong about that I need to double check my configuration.

Thanks,
