Question

我试图在SailsJS的策略中成功地序列化和反序列化用户。一个例子就是：

userAuth

var passport = require('passport');

module.exports = function (req, res, next) {

  // Check for authorization headers
  if(req.get('authorization')){
    passport.authenticate('basic', { session: false }, function(err, user, info) {
      if ((err) || (!user)) {
        return res.json(
          {'status':0,
            'message':'incorrect username or password'}
        );
      }
      req.logIn(user, function(err) {
        if (err) res.send(err);
        next();
      });
    })(req, res);
  }else{
    // If authentication via session, make sure that authorization headers are off
    var is_auth = req.isAuthenticated();
    if (is_auth) {
      // Ensure that session remembers that user is logged in,
      // so that views can reference to them
      req.session.isAuthenticated = true;
      if (req.user.doctor){
        req.session.isDoctor = true;
      }else{
        req.session.isDoctor = false;
      }
      return next();
    }else{  // User is not allowed
      req.session.isAuthenticated = false;
      res.status(401);
      res.view("user/login");
    }
  }

};

如您所见，console.log时req.user的反序列化不仅仅为反序列化对象提供了帮助。但是，当我调用它时，我的usercontroller：login似乎没有反序列化req.user。更多信息见下文：

login

process: function(req, res){
    passport.authenticate( ['local'] , function(err, user, info) {
      if ((err) || (!user)) {
        req.session.flash = {
          message : "incorrect username or password"
        }
        return res.redirect('/user/login');
      }
      req.logIn(user, function(err) {
        if (err) res.send(err);
        req.session.user = user;
        console.log(req.user);
        if(req.user.doctor){
          return res.redirect('/assessment/index');
        }else{
          return res.redirect('/user/show/'+req.session.user.id);
        }

      });
    })(req, res);
  },

console.log

{ username: 'username',
  createdAt: Mon Feb 09 2015 19:59:04 GMT+0800 (SGT),
  id: '54d8a108322359745faf0c5b' }

我误解了什么吗？我需要从req.user中检索反序列化的对象，现在看来我唯一的选择是做一个手动User.find（id ..）。任何帮助表示赞赏！（：

我发现在passport.authenticate内，有一个对象在它的回调中返回。因此，req.user现在将是由passport.use(new LocalStrategy(..)的回调创建的返回用户。

为了解决这个问题，我们必须为req.user添加我们想要的属性。现在它看起来像这样：

var returnUser = {
            username: user.username,
            doctor: user.doctor,
            createdAt: user.createdAt,
            id: user.id
          };
          return done(null, returnUser, {
            message: 'Logged In Successfully'
          });

PassportJS req.user没有反序列化
