Print passport data of connected sockets in a room

[marcogreselin]

I'm using passport.socketio to get user credentials and I want to print to the console the list of connected users in a given room every time a user connect. Currently I have the following:

io.use(passportSocketIo.authorize({
    key: 'connect.sid',
    secret: 'yuppy',
    store: sessionStore,
    cookieParser: cookieParser,
}));

io.on('connection', function(socket){
    console.log('a user connected');
    socket.on("logon", function () {
        socket.join(socket.request.user.companyid);
        console.log(io.nsps['/'].adapter.rooms[socket.request.user.companyid])
    })
});

But it prints something like:

Room { sockets: { '/#PteHXocxKH8Ctv6TAAAB': true }, length: 1 }

How can I print the Passport data?

[jfromaniello]

can you try something like this:

var currentRoom = io.nsps['/'].adapter.rooms[socket.request.user.companyid];
var currentUsersInRoom = currentRoom.sockets.map(s => s.request.user);
console.dir(currentUsersInRoom);

I haven't tested this, the reason I have to believe this should work is because of this doc Socket#request which states:

A getter proxy that returns the reference to the request that
originated the underlying engine.io Client. Useful for accessing
request headers such as Cookie or User-Agent.

console.log(room) will not show this because is not a enumerable property maybe.

Let me know if if works

I get:

Missing error handler on `socket`.
TypeError: Cannot read property 'sockets' of undefined

[marcogreselin]

Sorry this is the error:

TypeError: currentRoom.sockets.map is not a function

Yes, is a little bit more complicated than what I though. Here is an answer on SO:

http://stackoverflow.com/questions/6563885/socket-io-how-do-i-get-a-list-of-connected-sockets-clients

Maybe something like this:

function findClientsSocket(roomId, namespace) {
    var res = []
    , ns = io.of(namespace ||"/");    // the default namespace is "/"

    if (ns) {
        for (var id in ns.connected) {
            if(roomId) {
                var index = ns.connected[id].rooms.indexOf(roomId) ;
                if(index !== -1) {
                    res.push(ns.connected[id]);
                }
            } else {
                res.push(ns.connected[id]);
            }
        }
    }
    return res;
}
//then

var users = findClientsSocket(socket.request.user.companyid).map(s => s.request.user);

console.dir(users, { depth: 10 });

This is what I get in ns.connect. Does not look like an array to me. It does not look like an object either. I don't know.

is an object and the expression for (var id in ns.connected) { will iterate over the keys, the id will be something like this '/#AKNsIaR5Mu89frJBAAAB'
