node.js的express框架下的登录注册

Question

注册页面没问题，能够成功注册新的账号，但是登录页面，输入账号密码后，却显示404！

//这是我登录页面的app.js代码，哪里出问题了？我是按照网上教程做的，注册哪方面没问题，连的是MYSQL！！
router.get('/login', function(req, res) {
    if(req.session.islogin){
        res.locals.islogin=req.session.islogin;
        }
    if(req.cookies.islogin){
        req.session.islogin=req.cookies.islogin;
        }
    res.render('login', { title: '用户登入',test:res.locals.islogin });
    })
    .post(function(req, res) {
        client=usr.connect();
        result=null;
        usr.selectFun(client,req.body.username, function (result) {
                if(result[0]===undefined){
                    res.send('没有该用户');
                    }else{
                    if(result[0].password===req.body.password){
                        req.session.islogin=req.body.username;
                        res.locals.islogin=req.session.islogin;
                        res.cookie('islogin',res.locals.islogin,{maxAge:60000});
                        res.redirect('/home');
                        }else
                        {
                         res.redirect('/login');
                        }
                    }
            });
}); 

  function  selectFun(client,username,callback){
         //client为一个mysql连接对象
         client.query('select password from demo where username="'+username+'"',function(err,results,fields){
                 if(err) throw err;

                 callback(results);
             });
     }
