“信息-socket.io啟動”丟失

Question

我正在嘗試向我的應用程序添加套接字，並且通常情況下如果一切順利，我應該會看到類似的內容：

info  - socket.io started
Listening { address: '0.0.0.0', family: 'IPv4', port: 443 }

但是，我所看到的是：

Listening { address: '0.0.0.0', family: 'IPv4', port: 443 }

這只能表示套接字不起作用。 這是我的套接字代碼：

var sockets = require('socket.io').listen(server).of('/elyes');

sockets.use(function (socket, next) {
  // Read cookies from handshake headers
  var handshakeData = socket.request;
  var cookies = cookie.parse(handshakeData.headers.cookie);
  // We're now able to retrieve session ID
  var sessionID;
  if (cookies['connect.sid']) {
    sessionID = connect.utils.parseSignedCookie(cookies['connect.sid'], sessionSecret);
  }
  // No session? Refuse connection
  if (!sessionID) {
    callback('No session', false);
  } else {
    // Store session ID in handshake data, we'll use it later to associate
    // session with open sockets
    handshakeData.sessionID = sessionID;
    // On récupère la session utilisateur, et on en extrait son username
    sessionStore.get(sessionID, function (err, session) {
      if (!err && session && session.username) {
        // On stocke ce username dans les données de l'authentification, pour réutilisation directe plus tard
        handshakeData.username = session.username;
        handshakeData['pwdHash']=session.pwdHash;
        // OK, on accepte la connexion
        callback(null, true);
      } else {
        // Session incomplète, ou non trouvée
        callback(err || 'User not authenticated', false);
      }
    });
  }
});

var connections = {};
sockets.on('connection', function (socket) { // New client

    //========================================================= 
    socket.handshake['socket']=socket;
    socket.handshake['sockets']=sockets;
    connectedClients[socket.handshake.pwdHash]=socket.handshake

    broadcastToClients=sockets;
    if (connectedBoxs[socket.handshake.pwdHash]!=undefined) {
        //console.log(sockets['checkConnectivityInterval']);
        if (connectedClients[socket.handshake.pwdHash].checkConnectivityInterval!=undefined) 
            clearInterval(connectedClients[socket.handshake.pwdHash].checkConnectivityInterval);
            if (connectedBoxs[socket.handshake.pwdHash].stream!=undefined) 
            connectedClients[socket.handshake.pwdHash]['checkConnectivityInterval']=setInterval(function(){connectedBoxs[socket.handshake.pwdHash].stream.push('PresenceCheck\n')
                                                                                                            }, 2000); 
        //console.log(sockets['checkConnectivityInterval']);
    }
    else{
        sockets.emit('isBoxOnline', false);
    }

    //numClient++;
    //connectedClients[numClient]=socket;
  //socket.emit('message', Date.now());
  var sessionID = socket.handshake.sessionID; // Store session ID from handshake
  //console.log(socket.handshake);
  // this is required if we want to access this data when user leaves, as handshake is
  // not available in "disconnect" event.
  var username = socket.handshake.username; // Same here, to allow event "bye" with username
  if ('undefined' == typeof connectedClients[sessionID]) {
    connectedClients[sessionID] = { "length": 0 };
    // First connection
    sockets.emit('join', username, Date.now());
  }
  // Add connection to pool
  connectedClients[sessionID][socket.id] = socket;
  connectedClients[sessionID].length ++;

    socket.on('disconnect', function () {
       // Is this socket associated to user session ?
       var userConnections = connectedClients[sessionID];
       if (userConnections.length && userConnections[socket.id]) {
         // Forget this socket
         userConnections.length --;
         delete userConnections[socket.id];
       }
       if (userConnections.length == 0) {
        console.log("================================");

我在這里做錯了什么？

原來這只是一個版本問題：

諸如“ info-socket.io starts”之類的信息消息不會在1.0版本中顯示，而僅在0. *版本中顯示。 因此，如果您正在運行0. * socket.io代碼，同時在package.json中具有1.0 socket.io版本，則需要做的是：

• 最快的方法是在package.json中安裝相同的版本：

  npm在此處安裝socket.io@insert.your.version。

• 或保持最新的socket.io版本並相應地編輯代碼。 例如：

  io.set（'authorization'，function（handshakeData，callback）{變成：

  io.use（function（socket，next）{var handshakeData = socket.request;

我建議這篇文章介紹如何遷移到1.0：socket.io/docs/migrating-from-0-9/
