How to download old version files?

[kazukiaaaa]

When downloading minor version 0.5 I understand that you can get the file by the following URL.
URL:https://tenant.sharepoint.com/sites/base/_api/web/GetFileByServerRelativeUrl('/sites/base/sample.txt')/versions(5)/$value

Is it possible to download a file from the above URL using this function?
function: ctx.web.get_file_by_server_relative_path(file_url).download(local_file).execute_query()

Where do you get "/versions(5)/$value" from?

I'm still having trouble with all examples, I can read the library site but I'm not able to read items in a folder

Greetings!

Managing file versions were somewhat indeed limited and the only option to download the content for a specific version was to construct a custom request.

Starting from 2.3.8 version the library natively supports managing file versions, here are a few examples:

Example: download a specific file version content

ctx = ClientContext(test_team_site_url).with_credentials(credentials)
file_url = "/sites/team/Shared Documents/Guide.docx"
version = ctx.web.get_file_by_server_relative_path(file_url).versions.get_by_id(512)  #address file version by version identifier
download_path = os.path.join(tempfile.mkdtemp(),  os.path.basename(file_url))
with open(download_path, "wb") as local_file:
    file = version.download(local_file).execute_query()

Example: delete a file version

ctx = ClientContext(test_team_site_url).with_credentials(credentials)
file_url = "/sites/team/Shared Documents/Guide.docx"
target_file = ctx.web.get_file_by_server_relative_path(file_url)
versions = target_file.versions.top(1).get().execute_query()
versions[0].delete_object().execute_query()

All another API methods are also supported.
