Basic Access Authentication in Plug applications.
Add Blaguth as a dependency to your mix.exs file:
defp deps do
[{:blaguth, "~> 1.1.0"}]
endAfter you are done, run mix deps.get in your shell to fetch the dependencies.
Add Blaguth on top of a Plug Stack as follows:
defmodule CavePlug do
import Plug.Conn
use Plug.Builder
plug Blaguth, realm: "Secret",
credentials: {"Ali Baba", "Open Sesame"}
plug :index
def index(conn, _opts) do
send_resp(conn, 200, "Hello Ali Baba")
end
endIf you need more precise control over authentication process:
defmodule AdvancedPlug do
import Plug.Conn
use Plug.Router
plug Blaguth
plug :match
plug :dispatch
get "/" do
send_resp(conn, 200, "Everyone can see me!")
end
get "/secret" do
if authenticated?(conn.assigns) do
send_resp(conn, 200, "I'm only accessible if you know the password")
else
Blaguth.halt_with_login(conn, "Secret")
end
end
defp authenticated?(%{credentials: {user, pass}}) do
User.authenticate(user, pass)
end
