如何在复杂的mongoDb模式中发布到嵌套字段

我有一个mongoDb模式，我想向其发出发布请求，但是我遇到了一些问题。以下是在我的应用程序的根目录中找到的model文件夹中的架构。

const mongoose = require('mongoose');
let Schema = mongoose.Schema;
const userSchema = new Schema({
UserID: {
    type: mongoose.Schema.Types.Mixed,
  },
  User_Info: {
    First_Name: {
      type: String,
    },
    Last_Name: {
      type: String,
    },
    Current_Address: {
      type: String,
    },
    Email_Address: {
      type: String,
    },
  },
      Phone_Numbers: [{
        Home_Phone: {
          type: Number,
        },
        Work_Phone: {
          type: Number,
        },
        Cell_Phone: {
          type: Number,
        },
            Phone_verified: [{
              Home: Boolean,
              Work: Boolean,
              Cell: Boolean,
            }],
      }],
})
const User = mongoose.model('User', userSchema);
module.exports = User;

我也有一个Express Server API，如下所示

const router = express.Router();
const ComplexPost = require('../models/ComplexPost');

    router.get('/', async (req, res) => {
        try{
            const complexposts = await ComplexPost.find().sort({date:-1});
                res.json(complexposts);
        }   catch(err){
                res.json({message: err});
        }
    });

  router.post('/', async (req, res) => {
    ComplexPost.create({
        UserID: req.body.userid,
        User_Info: req.body.userinfo,
        First_Name: req.body.firstname,
        Last_Name: req.body.lastname,
        Current_Address: req.body.currentaddress,
        Email_Address: req.body.emailaddress,
        Phone_Numbers: req.body.phonenumbers,
        Home_Phone: req.body.homephone,
        Work_Phone: req.body.workphone,
        Cell_Phone: req.body.cellphone,
        Phone_Verified:req.body.phoneverified,
        Home: req.body.home,
        Work: req.body.work,
        Cell: req.body.cell,
    });
    try{
    await ComplexPost.save()
    res.redirect('/');
    }catch(err){
        res.json({message: err});
    }
});

module.exports = router;

在我的index.js文件中，我有以下代码；

const express = require('express');
const mongoose = require('mongoose');
const cors = require('cors');
const path = require('path');
const app = express();
const bodyParser = require('body-parser');

// Middlewares
require('dotenv/config');
app.use(cors());
app.use(bodyParser.json());

// Body Parser Middleware 
app.use(express.json());
app.use(express.urlencoded({ extended: false}));

app.use(bodyParser.urlencoded({
    extended: true
  }));

// Import routes
const complexRoute = require('./server/complexPost');
app.use('/complex', complexRoute);

// Serving static folder
app.use(express.static(path.join(__dirname, 'public'))); 

// Connect to DB
mongoose.connect( 
    process.env.DB_CONNECTION, 
    {  useNewUrlParser: true ,
       useUnifiedTopology: true, 
    },
    () => console.log('Connected to DB')
);

const port = process.env.PORT || 1100;
app.listen(port, () => console.log(`server started on port ${port}`));

当我尝试使用Postman进行发帖请求时，如下所示；

{
    "userid": "hi",
    "userinfo[firstname]": "Albert",
    "userinfo[lastname]": "Attakora",
    "userinfo[currentaddress]": "Kumasi",
    "userinfo[emailaddress]": "[email protected]",
    "phonenumbers[homephone]": ["alb"],
    "phonenumbers[workphone]": ["031"],
    "phonenumbers[cellphone]": ["02098767865"]
}

我得到的结果没有userinfo和电话号码详细信息

[
    {
        "_id": "5eca8b45feeb163e7cc46662",
        "UserID": "hi",
        "Phone_Numbers": [],
        "__v": 0
    }
]

请我缺少什么。是堆栈。
