How to GET an object with a specific versionId from S3

[duffau]

I'm trying to retrieve an S3 object with a specific versionId. In AWS's REST API documentation the versionId should be placed as a named parameter ?versionId=<the version ID>. But appending this string to the path of s3HTTP returns a "NoSuchKey".

Looking into the function setup_s3_url called in line 93 in s3HTTP.R
it percent-encodes the URL, so characters like "=" and "&" are mapped to "%3F" and "%3D" respectively.

This happens in line 358 of setup_s3_url in s3HTTP.R, where utils::URLencode is called with the parameter reserved = TRUE which makes all reserved characters like "=" and "&" be percent-encoded.

I understand that one would want to sanitize the URL, but is this a bug or a feature?

If it's a feature, how should I pass the versionId argument to s3HTTP and the other more high level functions like s3read_using?

> aws.s3::s3HTTP(verb = 'GET', bucket = 'my_bucket_name', path = object_path)
