Hello,
I’m trying to use channels and sockets on phoenix.
Here is what I have to handle sockets:
channel "discussion:*", Flux.DiscussionChannel
transport :websocket, Phoenix.Transports.WebSocket
def connect(%{"token" => token}, socket) do
case Flux.Guardian.decode_and_verify(token) do
{:ok, claims} ->
case Flux.Guardian.resource_from_token(token, claims["sub"]) do
{:ok, user} ->
{:ok, assign(socket, :current_user, user)}
{:error, _reason} ->
:error
end
{:error, _reason} ->
:error
end
end
def connect(_params, _socket), do: :error
def id(socket), do: "users_socket:#{socket.assigns.current_user.id}"
end
And here is my channel:
def join("discussion:" <> discussion_id, _params, socket) do
discussion = Repo.get_by(Flux.Discussion, id: discussion_id)
response = %{
discussion: Phoenix.View.render_one(discussion, Flux.Discussion, "read.json"),
}
{:ok, response, assign(socket, :discussion, discussion)}
end
def terminate(_reason, socket) do
{:ok, socket}
end
end
But, when I’m connecting from the front in local I keep getting an error 403: Forbidden.
I get no errors messages on the server terminal. It looks like websockets are not activated there. I double check the socket endpoint of the server and it must be good. I don’t understand.
Thanks for help.
