Passport的'req.user'有时会变得不确定

I am using passport for authorization and I am saving the session in mongodb using 'connect-mongo-session' module. I noticed that after sometime when I try to login the req.user object becomes undefined, although the session object is present in the database and passport and session details are present in the req object. Here is my session setup:

我使用护照进行授权，我使用'connect-mongo-session'模块在mongodb中保存会话。我注意到，在我尝试登录req.user对象的某个时间之后变为未定义，尽管会话对象存在于数据库中，并且护照和会话详细信息存在于req对象中。这是我的会话设置：

let store;

if(env === "development")
    store =  new MongoDBStore({  //Allows session to be stored and retreived even when server restarts.
  uri: config.db,
  collection: 'mySessions'
  })

else {
   store =  new MongoDBStore({  //Allows session to be stored and retreived even when server restarts.
  uri: config.db,
  collection: 'Cosmos'
  })
}

  app.use(session({
    store: store,
    saveUninitialized: true,
    resave: true,
    secret: config.app.sessionSecret
  }));

  app.use(passport.initialize());
  app.use(passport.session());

and here is the code responsible for serializing and :

这是负责序列化的代码，并且：

    passport.serializeUser((user, done) => {
    done(null, user.id);
});

// Use Passport's 'deserializeUser' method to load the user document
passport.deserializeUser((id, done) => {
    User.findOne({
        _id: id
    }, '-password -salt', (err, user) => {
        done(err, user);
    });
});

I was able to solve the problem by changing saveUninitialized to false and resave to false, so it looks like this now:

我能够通过将saveUninitialized更改为false并重新保存为false来解决问题，所以它现在看起来像这样：

    app.use(session({
      store: store,
      saveUninitialized: false,
      maxAge: 1000 * 60 * 60 * 84, // I added this just in case
      resave: false,
      secret: config.app.sessionSecret
  }));
