ExpressJS/Mongodb POST 请求和丢失用户数据

Question

我有一个 NodeJS 应用程序，我正在尝试向我的用户个人资料页面添加“新票证”功能。

以下是流程的工作方式 - 1. 用户提交在我的 mongodb 中创建新票的请求 2. 个人资料页面重新加载并在“最近的票证”部分显示新创建的票证。 （我可以轻松检索先前创建的票证）

但是，当我提交发布请求并尝试重新加载个人资料页面时，我会丢失用户数据。 （即未定义用户）。

router.post('/addTicket',  [
    check('phonenumber', 'user phone number required').not().isEmpty(),
    check('requestDevice', 'A device is required').not().isEmpty(),
    check('userDescription', 'A brief description is required').not().isEmpty(),
], function(req,res,){
    var userDescription = req.body.userDescription;
    var requestDevice     = req.body.requestDevice;
    var phonenumber = req.body.phonenumber;

    const result = validationResult(req);
    var errors = result.errors;

    if (!result.isEmpty()) {
        res.render('profile', {

                errors: errors,
                requestDevice: requestDevice,
                userDescription: userDescription,       
        });
    } else {
        console.log(phonenumber);
        var newTicket = {
            id: Math.random().toString(36).substring(2),
            requestDevice: requestDevice,
            userDescription: userDescription,
            openDate: Date.now(),
            closeDate: "",
            techComment: "",
            status : "open",
        }

        User.updateOne( {phonenumber: phonenumber }, {$push: {"tickets":  newTicket  } }, false, function(err, doc) {
            if(err){
                    res.send(err);
                } else {
                    console.log('ticket Added...');
                    res.redirect('/profile', {user:req.session.user}); //I know this req.session.user usage is probably not correct, but I've just been trying everything.
                }
        });


    }
});

还有我的控制台

    ReferenceError: D:\users\admin\desktop\from laptop\itspot.v.1.0.0\views\profile.ejs:59
    57|     <div class="w3-display-container w3-center w3-mobile" style="height: 300px">

这是个人资料路线

router.get('/profile', ensureAuthenticated, function(req,res){
    res.render('profile');
});

这就是我的 app.js 文件

var routes = require('./routes/index');
var services = require('./routes/services');
var users = require('./routes/users');
var info = require('./routes/info');
var admins = require('./routes/admins');

var app = express();

db.on('error', console.error.bind(console, 'connection error'));
db.once('open', function () {
  console.log('db is connected');
});

app.use(helmet());
//view engine

app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');

//set static folder
app.use(express.static(path.join(__dirname, 'public')));
app.use('/css', express.static(__dirname + '/node_modules/w3-css'));
//body parser
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
//Express Session Middleware
app.use(session({
    secret: 'this is super secret meow',
  store: new MongoStore({mongooseConnection: db}),
    saveUninitialized: true,
    resave: true,
  cookie: {
    httpOnly: false,
    secure: false,

  }
}));

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

// Express Validator Middleware
/*app.use(expressValidator({
  errorFormatter: function(param, msg, value) {
      var namespace = param.split('.'), 
      root    = namespace.shift(),
      formParam = root;

    while(namespace.length) {
      formParam += '[' + namespace.shift() + ']';
    }
    return {
      param : formParam,
      msg   : msg,
      value : value
    };
  }
 })); */

// Connect-Flash Middleware
app.use(flash());
app.use(function (req, res, next) {
  res.locals.messages = require('express-messages')(req, res);
  next();
});

//Access Globals
app.get('*', function(req, res, next){
  res.locals.user = req.user || null;
  next();

});



// Define Routes
app.use('/', routes);
app.use('/users', users);
app.use('/services', services);
app.use('/info', info);
app.use('/admins', admins);


app.listen(3000);
console.log('Server started on port 3000');

添加 Mongoose 架构

var mongoose = require('mongoose');

var userSchema = mongoose.Schema({
    name: {
        fname:{type: String, maxlength: 30, minlength: 1 },
        lname: {type: String, maxlength: 30, minlength: 1}
    },

    role: {type: String, default: "user"},

    email: {
        type: String,
        trim: true,
        lowercase: true,
        unique: true,
    },
    phonenumber: { type: String, required: true, validate: /^\d{10}$/, unique: true },
    zipcode: String,
    password: String, 
    devices: [],
    tickets: [],
    creationDate: { type: Date, default: Date.now },
    isVerified: {type: Boolean, default: false},
    passwordResetToken: String,
    PasswordResetExpires: Date,
});


const tokenSchema = mongoose.Schema({
    _userId: {type: mongoose.Schema.Types.ObjectId, required: true, ref: 'User'},
    token: {type: String, required: true},
    createdAt: { type: Date, required: true, default: Date.now, expires: 43200 }
});

const Token = mongoose.model('Token', tokenSchema);
var User = mongoose.model('User', userSchema);

module.exports = {Token, User};

保存到我的数据库中的会话数据

 db.sessions.find().pretty()
{
        "_id" : "e9bmD-yK2Rsr0fDajeusrtMTCJpUm0pT",
        "expires" : ISODate("2019-11-29T19:49:43.182Z"),
        "session" : "{\"cookie\":{\"originalMaxAge\":null,\"expires\":null,\"secure\":false,\"httpOnly\":false,\"path\":\"/\"},\"flash\":{},\"passport\":{\"user\":\"5dccd8041ac5ab2eec6f2be7\"}}" //This is the correct user ID, I checked it against the User id in the db.
}

Answer 1

尝试重定向到/profile 路由而不是渲染视图

db.users.update( {phonenumber: phonenumber }, {$set: {"tickets":  [newTicket]  } }, false, function(err, doc) {
                if(err){
                        res.send(err);
                    } else {
                        console.log('ticket Added...');
                        res.redirect('/profile'); // Change render to redirect

                    }
            });

Answer 2

User.findOneAndUpdate( {phonenumber: phonenumber }, {$push: {"tickets": newTicket } }, {new: true}, function(err, doc) { if(err){ res.send(err); } else { console.log('ticket Added...', doc, 'this is updated data'); res.redirect('/profile', {user: doc});
