Only get response headers with Req?

I think making a HEAD request is the most straightforward. Other than that, either into: :self + cancel (though you’d probably have received some messages by then) or into: fun:

iex> Req.get!("https://httpbin.org/status/201", into: fn {req, resp}, acc -> {:halt, {req, resp}} end)
%Req.Response{
  status: 201,
  headers: %{
    "access-control-allow-credentials" => ["true"],
    "access-control-allow-origin" => ["*"],
    "connection" => ["keep-alive"],
    "content-length" => ["0"],
    "content-type" => ["text/html; charset=utf-8"],
    "date" => ["Fri, 08 Nov 2024 19:55:52 GMT"],
    "server" => ["gunicorn/19.9.0"]
  },
  body: "",
  trailers: %{},
  private: %{}
}
