Nodejs - module websocket-node :Comment faire fonctionner le serveur socket multi-client ?

Vous ne stockez pas les connexions côté serveur. Vous les configurez simplement sur le serveur pour communiquer directement avec le serveur. Si vous voulez que les messages allant au serveur soient renvoyés à tout le monde, vous devez configurer le .on('message', ...) fonction pour chaque connexion sur le serveur pour avoir ce comportement. Pour ce faire, vous devrez stocker les connexions au fur et à mesure de leur création. Essayez ceci :

var WebSocketServer = require('websocket').server;
var http = require('http');

var server = http.createServer(function(request, response) {
    console.log((new Date()) + ' Received request for ' + request.url);
    response.writeHead(404);
    response.end();
});
server.listen(5050, function() {
    console.log((new Date()) + ' Server is listening on port 5050');
});

wsServer = new WebSocketServer({
    httpServer: server,
    // You should not use autoAcceptConnections for production 
    // applications, as it defeats all standard cross-origin protection 
    // facilities built into the protocol and the browser.  You should 
    // *always* verify the connection's origin and decide whether or not 
    // to accept it. 
    autoAcceptConnections: false
});

function originIsAllowed(origin) {
  // put logic here to detect whether the specified origin is allowed. 
  return true;
}

//create an array to hold your connections
var connections = [];

wsServer.on('request', function(request) {
    if (!originIsAllowed(request.origin)) {
      // Make sure we only accept requests from an allowed origin 
      request.reject();
      console.log((new Date()) + ' Connection from origin ' + request.origin + ' rejected.');
      return;
    }
    var connection = request.accept('echo-protocol', request.origin);

    //store the new connection in your array of connections
    connections.push(connection);
    
    console.log((new Date()) + ' Connection accepted.');
    connection.on('message', function(message) {
        if (message.type === 'utf8') {
            console.log('Received Message: ' + message.utf8Data);

            //send the received message to all of the 
            //connections in the connection array
            for(var i = 0; i < connections.length; i++) {
                connections[i].sendUTF(message.utf8Data);
            }
        }
        else if (message.type === 'binary') {
            console.log('Received Binary Message of ' + message.binaryData.length + ' bytes');
            connection.sendBytes(message.binaryData);
        }
    });
    connection.on('close', function(reasonCode, description) {
        console.log((new Date()) + ' Peer ' + connection.remoteAddress + ' disconnected.');
    });
});
