body-perser 没有在 express.js 中解析我的请求

Question

I am trying to use Controller here.

This is my app.js:

var express = require('express');
var app = express();
const routes = require('./Routes/route');
const bodyParser = require('body-parser');

app.use('/', routes);

// support parsing of application/json type post data
app.use(bodyParser.json());

//support parsing of application/x-www-form-urlencoded post data
app.use(bodyParser.urlencoded({extended: true}));

var server = app.listen(8081); 

This is my route.js:

const express = require('express');

const router = express.Router();

const controller = require('../Controllers/controller');

router.get('/counter', controller.showCount);
router.post('/addcount', controller.addCount);

module.exports = router;

This is my controller.js:

    const db = require('../db-connect');

const showCount = (req, res) => {
    if(db.state === 'disconnected'){
        res.send('Server not connected');
    }
    else{
        db.query('select * from Count', (err, rows, fields) => {
            if (err) throw err

            res.send(rows);
        });
    }
};

const addCount = (req, res) => {
    console.log(typeof(req.body));
    res.send(req.body);
}

module.exports = {showCount, addCount};

Problem: It seems like requests are not being parsed. Not sure why.

I am using post man to send request. I am sending data as 'form-data' by postman.

Answer 1

you must add app.use('/', routes); under the bodyParser middleware

// support parsing of application/json type post data
app.use(bodyParser.json());

//support parsing of application/x-www-form-urlencoded post data
app.use(bodyParser.urlencoded({extended: true}));

app.use('/', routes);
