Question

正如标题所述，无论我在哪里调用req.user，它都会向我输出一个未定义的对象，并导致500 Internal Server Error。
这是我到目前为止的代码（不是全部，只是感兴趣的部分）：
app.js

    app.use(cookieParser());
    app.use(bodyParser.urlencoded({ extended: true }));
    app.use(bodyParser.json());
    app.use(session({
        secret: 'keyboard cat',
        resave: false,
        saveUninitialized: true,
        cookie: { secure: true }
      })); //This was added as a second temptative
    app.use(passport.initialize());
    app.use(passport.session());


    // config
    passport.use('local', new LocalStrategy({
        usernameField: 'email',
        passwordField: 'pwd',
        session: false
    },
        function (username, password, done) {
            User.findOne({ email: username }, (err, usr) => {
                if (err) { return done(err); }
                // TODO: refactor for right error message handling as below!!
                if (!usr)
                    return done(null, false, { success: false, status: 403, message: 'Incorrect username.' });
                if (!usr.authenticate(password))
                    return done(null, false, { success: false, status: 403, message: 'Incorrect password.' });
                if (!usr.verified)
                    return done(null, false, { succes: false, status: 400, message: 'User not confirmed' });
                delete usr.salt;
                delete usr.password;
                return done(null, usr);
            });
        })
    );

passport.serializeUser(function (user, done) {
    const tempUser = Object.assign({}, { x: user.id, y: user.email, z: user.salt });
    done(null, user.id);
});

passport.deserializeUser(function (id, done) {
    console.warn(`WE DID IT`);
    User.findById(id, function (err, user) {
        console.log(`id in input ${id}`);
        console.log(`deserializing user ${user}`);
        done(err, user);
    });
});

我用于身份验证的控制器：

exports.authenticate = (req, res) => {
  passport.authenticate('local', { session: false /*, failureCallback: failureCallback */}, (err, user, info) => {
    if (!err) {
      if (!user)
        res.json(info);
      else {
        var userCopy = Object.assign({}, user._doc);
        delete userCopy.password;
        delete userCopy.salt;
        delete userCopy.profilePicture;
        Activity.checkin.getActiveUserCheckin(userCopy._id, (err, activeCheckin) => {
          if(!err){
            if(!!activeCheckin) userCopy.activeCheckinOnStructure = activeCheckin.structureId;
            var token = jwt.sign(userCopy, require('../../secret'));
            res.send({ success: true, status: 200, token: token });
          }else{
            res.send({ success: false, status: 500, message: err });
          }
        });
      }
    }
  })(req, res);

};

我尝试过的事情：首先，我试图添加一个快速会话（如您在app.use（session）部分中所见）以添加Express'会话。然后，我尝试将用户设置为类似app.set（“ user”，user），但这并不好，因为在调用方法时我无法访问app变量。
在我看来，app.js部分和login部分的配置已经很好地完成了，并且护照应该自动将req.user字段连接起来，但是这并没有发生，我无法解释自己为什么这是真的吗

此特定问题的问题是从未调用过userSerializer。添加req.login解决了这一天

  passport.authenticate('local', { session: true /*, failureCallback: failureCallback */}, (err, user, info) => {
    if (!err) {
      if (!user)
        res.json(info);
      else {
        var userCopy = Object.assign({}, user._doc);
        delete userCopy.password;
        delete userCopy.salt;
        delete userCopy.profilePicture;
        Activity.checkin.getActiveUserCheckin(userCopy._id, (err, activeCheckin) => {
          if(!err){
            if(!!activeCheckin) userCopy.activeCheckinOnStructure = activeCheckin.structureId;
            var token = jwt.sign(userCopy, require('../../secret'));
            req.login(user, function(err) {
              if (err) {
                return res.status(401).json(err);
              } else {
                res.send({ success: true, status: 200, token: token });
              }
            });
          }else{
            res.send({ success: false, status: 500, message: err });
          }
        });
      }
    }
  })(req, res);

};

req.user未通过Passport接线
