Node.js express - POST 请求的正文始终为空

Question

I am trying to read the body of POST request using Express in Node.JS framework. I send a HTTP POST request using HTML form. I detected a POST request on WireShark with the following data:

This shows that the request is sent successfully. I expected JSON format, which is the one that Express successfully parsed for me, but this format just doesn't seem to work no matter what I tried. My current implementation goes like this:

var express = require('express');
var bodyParser = require('body-parser');
var app = express();
var jsonParser = bodyParser.json()

//Import static files
app.use(express.static('../public'))

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));

app.post('/', jsonParser, (req, res) => {
    console.log(req.body);
    res.send(200);
});

app.listen(port, () => console.log("Server started"));

No matter what I try from other posts, it still does not seem to return me any data.

Does anyone have an idea how to fix this problem?

Why to you use 'jsonParser' in the app route? Try something like:

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

const app = express();
app.use(bodyParser.urlencoded({ extended: true }));

app.post('/post-test', (req, res) => {
    console.log('Got body:', req.body);
    res.sendStatus(200);
});
