node.js – express无法进行身份验证

我一直关注微软视觉学院(mva)完成的平均堆栈视频.我对MVA模块3感到震惊.当我输入用户名和密码时,它总是重定向到失败路由.

passport.js：

passport.use('signup',new LocalStrategy({
        passReqToCallBACk : true // allows us to pass BACk the entire request to the callBACk
    },function(req,username,password,donE) {

        if (users[username]){
            console.log('User already exists with username: ' + userName);
            return done(null,falsE);
        }

        //store user in memory 
        users[username] = {
            username: username,password: createHash(password)
        }

        console.log(users[username].username + ' Registration successful');
        return done(null,users[username]);
    })
);

authenticate.js：

router.get('/success',res){
    res.send({state: 'success',user: req.user ? req.user : null});
});

//sends failure login state BACk to angular
router.get('/failure',res){
    res.send({state: 'failure',user: null,message: "Invalid username or password"});
});

//log in
router.post('/login',passport.authenticate('login',{
    successRedirect: '/auth/success',failureRedirect: '/auth/failure'
}));

我实际上遵循了https://github.com/hwz/chirp/tree/master/module-3中给出的步骤

任何帮助表示赞赏.提前致谢 ：)
