How to download a file with Finch which is redirected

There’s no built-in feature inside Finch which follow redirects. You can write your own wrapper for this. For example

def do_get(url, name, depth \\ 123)
def do_get(:undefined, _, _), do: {:error, :bad_redirect}
def do_get(url, name, 0), do: {:error, :maximum_depth_exceeded}
def do_get(url, name, depth) do
  :get
  |> Finch.build(url)
  |> Finch.request(name)
  |> case do
    {:ok, %Finch.Response{status: 302, headers: headers}} ->
      "location"
      |> :proplists.get_value(headers)
      |> do_get(name, depth - 1)

    other ->
      other
  end
end

Thank you, yes I know we can get from location, but I thought there is an option for this problem.

Apologies that I am not answering your question directly but I would strongly recommend you use Tesla with Finch below. Tesla has a number of these super useful wrappers, redirect following being one of them.

Thank you for suggestion, sure I will test it

As I’ve said, there’s no such option. I’ve read the sources and it doesn’t support redirects out of the box
