Javascript Passport不设置cookies？

我试图在有人登录时将用户分配到cookie，但passport似乎没有将数据分配到cookie。您可以在下面找到代码：

app.use(bodyParser.urlencoded({
  extended: true
}));


app.use(cookieParser());

app.use(bodyParser.json());


app.use(passport.initialize());

//Use session
app.use(passport.session({ secret: '=Mx;D5F}t&iJZ&w-g;FLK:%QavZgZt', cookie: { maxAge: 0 }, resave: true, saveUninitialized: true }))

app.use(express.static('server/public'));


//Set view engine
app.set('views', 'server/views')
app.set('view engine', 'pug');


//Set passport local strategy
passport.use(new LocalStrategy({ usernameField: "email" },
  function (email, password, done) {
    User.findOne({ 'email': email }, async function (err, user) {
      console.log('user requested password caught in passport: ', password);
      if (err) { return done(err); }
      if (!user) {
        return done(null, false, console.log('Wrong username'));
      }
      return await user.validatePassword(password, function (err, result) {
        if (err || !result) return done(null, false, console.log('Wrong Password'));
        return done(null, user);
      })
    });
  }
));

// serialize user object
passport.serializeUser(function (user, done) {
  done(null, user.id);
});

// deserialize user object
passport.deserializeUser(function (id, done) {
  User.findById(id, function (err, user) {
    done(err, user);
  })
});

这是登录路径：

//Route for user login
app.post('/auth/local/signin',
  function (req, res, next) {
    passport.authenticate('local', function (err, user, info) {
      console.log(err);
      console.log(user);

      if (err) {
        console.log('passport.authenticate: error')
      } else if (!user) {
        console.log('passport.authenticate: user')
      } else {
        console.log('next handler')
        console.log('Cookie assigned: ' + req.user)
        return res.redirect('/dashboard')
      }

      return res.redirect('/login')

    })(req, res, next)
  }
)

正如您所看到的，我尝试记录req.user，它返回未定义的

---

但是，console.log（user）从数据库返回用户，这正是我想要的。

请求来自express，而不是passport。对于cookies，您应该检查

req.cookies

@DarknessZX，我已经用console.log（'Cookie assigned:'，req.cookies）尝试过了，它返回Cookie assigned:[Object:null prototype]{}您尝试过增加

maxAge

？
