Download binary data in POST request to a file
I am sending binary data to Phoenix via a POST request. I need to download the received data to a file for further processing (untar, run pdflatex, send link back to the pdf file). How do I so the download?
the data comes in from an Elm client, The controller appears to accept the data – no errors – but I don’t see the data when I do IO.inspect params

OK, its saving the POSTed data to file now:
def process(conn, params) do
IO.inspect params, label: "params for 'process'"
{:ok, body, conn} = Plug.Conn.read_body(conn)
IO.inspect body, label: "BODY"
{:ok, file} = File.open "tarfileXXX.tar", [:write]
IO.binwrite file, body
File.close file
conn |> render("pdf.json", url: "OK")
end
More work to do, but this was the blocker
