Question

我为表单上的字段创建了mongoose模式类型数组。我使用req.body.fieldName作为属性来访问值，但是当我对数组执行此查询时，它返回undefined，因为它不是键值对。如何在我的新路由处理程序中创建的模型中解析它？

这是我的架构和我的邮政路线处理程序。

const mongoose = require('mongoose');
const { Schema } = mongoose;

const StoreSchema = new Schema({
name : String,
  address: {
        street: String,
        crossStreet: String,
        city: String,
        state : String,
        zipcode : Number,
        country: String,
        formattedAddress: Array,
        location : {
            geoType : String,
            coordinates: Array
         }
     }

  })
module.exports = mongoose.model('Store', StoreSchema);

store.js文件

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

router.post('/api/store/register', (req, res, next) => {
      const store = new Store();
        store.address.street = req.body.street;
        store.address.crossStreet = req.body.crossStreet;
        store.address.city = req.body.city;
        store.address.state = req.body.state;
        store.address.zip = req.body.zip;
        store.address.country = req.body.country;
        store.address.formattedAddress = req.body.formattedAddress;
        store.location.geoType = req.body.geoType;
        store.location.coordinates = req.body.coordinates;
        store.save(() => {
            console.log('New store data is entered ' + store);
            res.redirect('/');
        });
})

第1步。npm install body-parser --save

第2步。var bodyParser = require('body-parser')

第3步。app.use(bodyParser.json());

如何使用node body-parser解析数组值？
