我正在尝试使用 Multer 将 3 张图像上传到数据库，我想将 image1 保存在 proImg 中，将 image2 保存在 proImg2 中，将 image3 保存在 proImg3 中。因此，每个产品将在网站上显示三张图片。那么如何使用 Node 和 Multer 将多个文件上传到 MongoDB？

产品.js

    const mongoose = require("mongoose")
    
    const productSchema = new mngoose.Schema({
    
        description: {
            type: String,
            required: true
        },
    
    
        proImg: {
            type: String,
            required: true
  
        },
    
        proImg1: {
            type: String,
            required: true
    
        },
    
        proImg2: {
            type: String,
            required: true
    
        },
    })
    
    let Product = mngoose.model('Product', productSchema, 'products');
    module.exports = Product;

      const multer = require("multer")
        var storage = multer.diskStorage({
            destination: function (req, file, cb) {
              cb(null, 'uploads/imgs')
            },
            filename: function (req, file, cb) {
              cb(null, file.originalname + '-' + Date.now() + '.png' )
            }

          var upload = multer({ storage: storage,
            limits: {
                fieldSize: 1024 * 1024 * 3,
              },
            });
        
            var uploadMultiple = upload.fields([{ name: 'image', maxCount: 10 }, { name: 'image2', maxCount: 10 } , 
            { name: 'image3', maxCount: 10 }])
        router.post('/addProduct',upload.array('Images', 10), (req,res)=> {
            const errors = validationResult(req)
       
            
            let Pro= new Product({
                title: req.body.ProName,

            })

                    console.log("error")
       .
