Guardian VerifyHeader Wrapper

verifiy_header.ex

defmodule MyAppWeb.Guardian.VerifyHeader do
  @moduledoc """
  This is a wrapper for Guardian.Plug.VerifyHeader, the difference being that
  we do not want the connection to be halted.

  @behaviour Plug

  def init(opts), do: Guardian.Plug.VerifyHeader.init(opts)

  def call(conn, opts) do
    conn = Guardian.Plug.VerifyHeader.call(conn, opts)
    # Since Guardian 1.x, the conn is automatically halted after being passed to the
    # error handler. We do want it to reach the downstream plugs, so we'll unhalt it.
    # see https://github.com/ueberauth/guardian/issues/401
    %{conn | halted: false}
  end
end

Good solution, but I added state to %{conn | halted: false, state: :unset}, to avoid Plug.Conn.AlreadySentError error
