Question

req.body就是{}。所有表单数据都不在req.body中。请注意，它在邮递员中很有用。

以下是服务器代码：

const _ = require('lodash');
const express = require('express');
const hbs = require('hbs');
const bodyParser = require('body-parser');
const {ObjectID} = require('mongodb');
const {mongoose} = require('./db/mongoose');

var {authenticate, authenticateAdmin} = require('./middleware/authenticate');

const port = process.env.PORT;
var app = express();

app.use(bodyParser.json());

app.set('view engine', 'hbs');

app.post('/users', (req, res) => {
    var body = _.pick(req.body, ['email', 'password']);
    console.log(body)
});

app.listen(port, () => {
    console.log(`Server is up on port ${port}`);
});

以下是相关的html部分：

<form action="/users" method="post">
    <input type="email" name="email">
    <input type="password" name="password">
    <button type="submit">Done</button>
</form>

谢谢！

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

您需要为编码正文添加此行。

req.body就像{}一样空
