app.js

var flash = require('connect-flash');
app.use(flash());
app.post('/loginaction',function(req,res){
    var user = new User(req.body.user);
    user.save(function(err){
        if(!err){
            req.flash('info','flash!!save!!');
            res.redirect('/');
        }else{
            res.redirect('/login');
        }
    });
});

jade

  form(method = 'post' ,action='/loginaction')
    fieldset
      legend register a user
      div.clearfix
        label Login
          div.input
            input(name='user[name]',class='xlarge')
            input(name='user[pwd]',type='password',class='xlarge')
           
          div.actions
            input(type='submit',value='save',class='btn primary')
            input(type='reset',value='reset',class='btn primary')
            input(type='button',value='cancel',class='btn primary')
  script alert(typeof flash);
  script alert(flash.info);

0.学习阶段，我只想在登陆成功的时候告诉用户一下。。。顺便存到session中保存登陆信息 1.flash.info undefined 。。。请问各位大牛 问题出在哪？ 2.node 3.X以后req.flash被req.session.messages = [‘foo’] ;替代，但是这玩意照着网上说的设置了

app.use(express.cookieParser());
app.use(express.session({
    secret : "hardwork!"
}));
app.use(express.session({ cookie: { maxAge: 60000 }}));

app.post('/loginaction',function(req,res){
    var user = new User(req.body.user);
    user.save(function(err){
        if(!err){
            req.session.messages = ['foo'] ; // jade页面上如何拿到呢？？？？？
            res.redirect('/');
        }else{
            res.redirect('/login');
        }
    });
});
