Try using GenServer for this.
My suggestion is as follows:
defmodule MyCustomizedClient do
use GenServer
use HTTPoison.Base
def start_link(opts) do
GenServer.start_link(__MODULE__, :ok, opts)
end
def fetch(my_custom_client_instance, endpoint) do
GenServer.cast(my_custom_client_instance, {:fetch, endpoint}) # cast is asynchronous
end
def handle_cast({:fetch, endpoint}, _state) do # I don't see the need of a state, but feel free
{:noreply, get(@url <> endpoint)}
end
def process_response_body(body) do
# treat response body as you will
end
# maybe other GenServer or HTTPoison callbacks you find necessary
end
