Sending custom string data from phoenix controller

I’m looking for a way to send send a custom string as a payload from an elixir controller.

The spec I’m working with expects something similar to this.

param1=value1\n
param2=value2\n

Name value pairs. One per line separated by a newline character.
How might one go about this?
Thank you for any help.

def some_action(conn, _params) do
  ...
  conn
  |> put_resp_content_type("text/whatever")
  |> send_resp(200, encode(payload))
end
defp encode(%{} = payload) do
  for {key, val} <- payload, into: "" do
    "#{key}=#{val}\n"
  end
end

what this mean in function encode, is equal defp encode(payload) when is_map(payload) ?

Yes but not only, it works for struct too. For example

%MyStruct{} = payload

This way You ensure pattern match will work only if payload is of a certain Struct, without the need to use guard.
