使用connect、express和socket.io,我试图允许我的应用程序在重新连接时获取会话细节。我的会话显然在客户端连接时工作,但如果我在浏览器上刷新页面,它就会忘记所有内容。
我的会话cookie肯定是一样的,所以不是这样的。
我的代码是从许多不同来源获取的片段的大杂烩,因为似乎没有一个完整的示例应用程序。
我错过了什么?
var qs = require('querystring'),
express = require('express'),
app = express.createServer(),
io = require('socket.io').listen(app.listen(8000)),
routes = require('./routes'),
pCookie = require('connect').utils.parseCookie,
Session = require('connect').middleware.session.Session,
RedStore= require('connect-redis')(express),
sStore = new RedStore();
// Configuration
app.configure(function(){
app.set('views', __dirname + '/views');
app.set('view engine', 'ejs');
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(express.cookieParser());
app.use(express.session({ store: sStore, secret: 'tehsecretz' }));
app.use(app.router);
app.use(express.static(__dirname + '/public'));
});
app.configure('development', function(){
app.use(express.errorHandler({ dumpExceptions: true, showStack: true }));
});
app.configure('production', function(){
app.use(express.errorHandler());
});
// Routes
app.get('/', routes.index);
io.sockets.on('connection', function (client) {
var hs = client.handshake,
session = hs.session;
console.log('A socket connected called: ' + hs.sessionId);
var intervalId = setInterval(function() {
hs.session.reload(function() {
hs.session.touch().save();
});
}, 60 * 1000);
if (!session.userName) {
// Prompts the user for a name on the frontend
client.emit('need-to-register');
}
client.on('message', function(msg, c) {
console.log(session);
console.log(msg);
});
client.on('register-user', function(data, fn) {
// This retrieves the user's name
// and - hopefully - saves it to the session.
data = qs.parse(data);
session.userName = data.username;
hs.session.save();
console.log('Saving: ', session);
fn('ok');
});
client.on('disconnect', function() {
clearInterval(intervalId);
});
});
io.set('authorization', function (data, accept) {
if (data.headers.cookie) {
data.cookie = pCookie(data.headers.cookie);
data.sessionId = data.cookie['connect.sid'];
data.sessionStore = sStore;
sStore.get(data.sessionId, function (err, session) {
if (err || !session) {
accept('Error', false);
} else {
console.log(data.sessionId, session);
data.session = new Session(data, session);
accept(null, true);
}
});
} else {
return accept('No cookie transmitted', false);
}
});

所以在Daniel Baulig's post中,他引用了标识符
sessionID
。我认为这只是不好的约定(因为我习惯使用camelCase),并立即在代码中将其更改为sessionId
。当我调试时,我在我的redis示例上打开了
MONITOR
ing,并注意到会话正在写入sess:undefined
。原来
sessionID
是特殊的,在内部被引用为实际的标识符。将sessionId
的所有示例更改为sessionID
可以让我更好地了解谁正在连接!hgncfbus2#
在“express.session”中添加“cookie”
