How to get the current url in phoenix framework

Question

I would like to know the current url with elixir / phoenix framework, how I can get this ?

Edit #1:

My nginx config file:

server {
        client_max_body_size 100M;

        listen  80;

        server_name *.babysittingbordeaux.dev *.babysittingparis.dev

        access_log  /usr/local/var/log/nginx/baby-access.log;
        error_log   /usr/local/var/log/nginx/baby-error.log;


        location / {
            proxy_pass http://127.0.0.1:4000;
        }
}

Code:

Atom.to_string(conn.scheme) <> "://" <> (Enum.into(conn.req_headers, %{}) |> Map.get("host")) <> conn.request_path

That example returns http://127.0.0.1:4000/, I would like to get http://www.babysittingbordeaux.dev/

I'm in development mode.

Answer 1

You can use Phoenix.Controller.current_url/1:

current_url(conn)

The endpoint configuration will define the URL:

config :my_app_web, MyAppWeb.Endpoint, url: [host: "example.com"]

Answer 2

If you are interested only in the request path you can use conn.request_path which holds a value like "/users/1".

To get the URL including the host you can use

MyApp.Router.Helpers.url(conn) <> conn.request_path

which would return a result like "http://localhost:4000/users/1".
