为什么需要。正文始终为空且为req。发送表单数据时,文件始终未定义

body-parser postman post express node.js

指数js公司

const express = require('express');
const app = express();
const mongoose = require('mongoose');
mongoose.Promise = global.Promise;
const config = require('./config/database');
const path = require('path');
const bodyParser = require('body-parser');
app.use(bodyParser.urlencoded({extended: true}));
app.use(bodyParser.json());
const router = express.Router();
const products = require('./routes/product')(router);
const port = process.env.PORT || 3030;
app.use('/products', products);

app.listen(port, () => {
    console.log('Listening on port ' + port + ' in ' + process.env.NODE_ENV + ' mode');
});

在产品中。js文件

let multer = require('multer');
let upload = multer();


module.exports = (router) => {

  router.post('/newProduct', (req, res) => {
          console.log('req');
          console.log( req.body );
          console.log( req.files );
})
}

例如

router.post('/newProduct', upload.array('files', 5), (req, res) => {
          console.log('req');
          console.log( req.body );
          console.log( req.files );
})

upload.single() upload.fields() 处理多个上传表单字段。但这一切在他们的页面中得到了更好的解释。
