如何在Mongoose中用req.body访问对象？

npm install express body-parser mongoose

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

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

const Schema = mongoose.Schema;

// 定义对象模型
const myObjectSchema = new Schema({
  name: String,
  age: Number,
  email: String
});

// 创建模型
const MyObject = mongoose.model('MyObject', myObjectSchema);

// 定义路由
app.post('/objects', (req, res) => {
  const myObject = new MyObject(req.body);
  myObject.save((err) => {
    if (err) {
      res.status(500).send(err);
    } else {
      res.status(200).send('Object saved successfully');
    }
  });
});
