Question

我使用here中的标准示例，其中包含：

app.get('/login/facebook',
  passport.authenticate('facebook'));

app.get('/login/facebook/return', 
  passport.authenticate('facebook', { failureRedirect: '/login' }),
  function(req, res) {     //req.user is populated
    res.redirect('/');
  });

app.get('/', function (req, res) {
    res.render('index.jade', { user: req.user });   //req.user is undefined
});

登录似乎工作正常。在/login/facebook/return我可以看到req.user及其详细信息。但在重定向到/后，req.user变为undefined。

还有什么我必须添加才能使其有效吗？

根据Passportjs Documentations，passport.initialize()和passport.session()（对于持久登录），应在app之后将express-session添加到express.session()。

来自文档：

请注意，启用会话支持完全是可选的，但建议大多数应用程序使用。如果启用，请务必在passport.session()之前使用app.configure(function() { app.use(express.static('public')); app.use(express.cookieParser()); app.use(express.bodyParser()); app.use(express.session({ secret: 'keyboard cat' })); app.use(passport.initialize()); app.use(passport.session()); app.use(app.router); });，以确保以正确的顺序恢复登录会话。

passport-facebook登录不会持续存在
