express4 session 不会用。以前用过express3 很不错。换了新就不行。粘出代码

app.use(cookieParser()); app.use(session({

keys: ['key1', 'key2'],

secureProxy: true }));

app.use(function(req,res,next){ var again = req.query.again||false;

var n = req.session.views || 0 req.session.views = ++n
***console.log(n); // n  值永远是1 *** if(req.session.curruser){ res.render('login/loginsuccess',{loginname:loginname,password:password}); } else{ res.render('login/login',{again:again}); }; }) app.listen(3000);
