我对 NodeJS 开发很陌生。我在我的 express 应用程序中使用session.socket.io插件，但是当我在sessionSockets.on ('connection', . ..
这是整个app.js：
var http = require('http'),
connect = require('express/node_modules/connect'),
express = require('express'),
app = express();
var cookieParser = express.cookieParser('Your secret key here'),
sessionStore = new connect.middleware.session.MemoryStore();
app.configure(function() {
app.set('port', process.env.PORT || 3000);
app.use(express.logger('dev'));
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(cookieParser);
app.use(express.session({
store: sessionStore
}));
app.use(app.router);
});
var server = http.createServer(app),
io = require('socket.io').listen(server);
var SessionSockets = require('session.socket.io'),
sessionSockets = new SessionSockets(io, sessionStore, cookieParser);
app.configure('development', function() {
app.use(express.errorHandler());
});
app.get('/', function(req, res) {
res.end("Welcome to the API server");
});
sessionSockets.on('connection', function(err, socket, session) {
console.log('-----------------------');
console.log(err.error);
console.log('-----------------------');
socket.emit('welcome', {
msg: 'You\'re now listening to the api.'
});
});
server.listen(app.get('port'), function() {
console.log("Express server listening on port " + app.get('port'));
});
客户端：
