我正在为注册用户创建聊天应用程序,使用 nodejs (0.8.15)、express (>3.0) 框架和 mongodb。
var express = require('express')
, http = require('http')
, path = require('path')
, io = require('socket.io');
var app = express()
, server = http.createServer(app)
, io = io.listen(server);
app.configure(function() {
app.set('port', process.env.PORT || 3000);
app.set('views', __dirname + '/views');
app.set('view engine', 'ejs');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(express.cookieParser('secret'));
app.use(express.session({cookie: {maxAge: 60000*100}}));
app.use(app.router);
app.use(express.static(path.join(__dirname, 'public')));
});
app.configure('development', function() {
app.use(express.errorHandler());
});
app.get('/chat', function(req, res) {
res.render('chat');
});
server.listen(app.get('port'), function() {
console.log("Express server listening on port " + app.get('port'));
});
io.sockets.on('connection', function (socket) {
socket.on('start-chat', function() {
// here i need to know req and res
// for example, i need to write:
// socket.username = req.session.username;
});
});
问:如何让 res 和 req 对象在像上面的代码一样聊天时与它们一起工作?还是我创建与用户身份验证聊天的方式错误?
谢谢!
最佳答案
您需要使用授权
。
var socketIO = require('socket.io').listen(port);
socketIO.set('authorization', function(handshakeData, cb) {
//use handshakeData to authorize this connection
//Node.js style "cb". ie: if auth is not successful, then cb('Not Successful');
//else cb(null, true); //2nd param "true" matters, i guess!!
});
socketIO.on('connection', function (socket) {
//do your usual stuff here
});
