extern crate actix_web;
extern crate sockjs;
use actix_web::*;
use actix::prelude::*;
use sockjs::{Message, Session, CloseReason, SockJSManager, SockJSContext};
struct Chat;
/// `SockJSContext` context is required for sockjs session
impl Actor for Chat {
type Context = SockJSContext<Self>;
}
/// Session has to implement `Default` trait
impl Default for Chat {
fn default() -> Chat { Chat }
}
/// Sockjs session trait
impl Session for Chat {
fn opened(&mut self, ctx: &mut SockJSContext<Self>) {
ctx.broadcast("Someone joined.")
}
fn closed(&mut self, ctx: &mut SockJSContext<Self>, _: CloseReason) {
ctx.broadcast("Someone left.")
}
}
/// Session has to be able to handle `sockjs::Message` messages
impl Handler<Message> for Chat {
type Result = ();
fn handle(&mut self, msg: Message, ctx: &mut SockJSContext<Self>)
{
// broadcast message to all sessions
ctx.broadcast(msg);
}
}
fn main() {
let sys = actix::System::new("sockjs-chat");
// SockJS sessions manager
let sm: Addr<Syn, _> = SockJSManager::<Chat>::start_default();
HttpServer::new(move || {
let manager = sm.clone();
Application::new()
// register SockJS application
.handler(
"/sockjs/", sockjs::SockJS::new(manager.clone()))})
