In Elixir, Phoenix, how to get session in other module as a module use Phoenix.Channel?

Question

In Elixir and Phoenix, I can get session in Controller by

Plug.Conn.get_session(conn, :id)

So how to get session in other module as a module use Phoenix.Channel ?

Answer 1

Plug.Conn is not available in Phoenix.Channel. Channels rely on Phoenix.Socket instead and you can use Phoenix.Token for authentication.

Here's a tutorial on how to authenticate channels in Phoenix.
