在Nodejs/Express中将带有其他键值参数的图像上传到postman

Question

现在，为了访问我的NodeJS中的这些值，我正在执行以下操作：

var express = require('express');
var bodyParser = require('body-parser');

const router = express.Router();
router.use(bodyParser.json());

router.post('/postData/uploadStory', function(req, res) {
    console.log(req.files);
    console.log(req.body);
     res.json("Hi");
})

如何访问图像和键值？

还查看了express-fileupload节点模块为我完成这项工作。

我是不是漏掉了什么？请帮忙。谢了。

multer是在Node.js中上传文件的最佳选择

为multer创建单独的文件夹，如multerhelper.js

const multer = require('multer');
let fs = require('fs-extra');

let storage = multer.diskStorage({
destination: function (req, file, cb) {
    fs.mkdirsSync(__dirname + '/uploads/images'); // fs.mkdirsSync will create folders if it does not exist
    cb(null, __dirname + '/uploads/images');
},
filename: function (req, file, cb) {
   console.log(file);

    cb(null, Date.now() + '-' + file.originalname);
 }
})

let upload = multer({ storage: storage });

let createUserImage = upload.single('photo');

let multerHelper = {
    createUserImage,
}

module.exports = multerHelper;

在路由导入MulterHelper文件中

const multerHelper = require("../helpers/multer_helper");

router.post('/upload/:userid',multerHelper, function(req, res) {
    console.log(req.files);
    console.log(req.body);
     res.json("Hi");
})
