express 抛出错误为`body-parser deprecated undefined extended`

all

在我的节点应用程序中,我使用的是 express。一切正常,但我在cmd. 我使用的都是更新的模块…

我的代码:

var express = require('express');
var bodyParser = require('body-parser');
var jade = require('jade');
var app = express();
app.set('view engine', 'jade');
app.set('views', __dirname + '/views');
app.use(express.static(__dirname + '/public'));


app.use(bodyParser.json()); // to support JSON-encoded bodies
app.use(bodyParser.urlencoded()); // to support URL-encoded bodies


app.get('/',function(req,res){
    res.render('index.jade');
});

app.get('/login',function(req,res){
    res.render('index.jade');
});

app.post('/login',function(req,res){
    console.log(req.body);
});

app.get('/signup',function(req,res){
    res.render('signup.jade');
});

var env = process.env.PORT || 3000;


app.listen(env, function(req, res){
    console.log('i am working!');
});

错误:

D:\myLogin>node app
body-parser deprecated undefined extended: provide extended option app.js:11:20 //why i am getting this?
i am working!
{ username: 'jbarif@gmail.com', password: 'pass' } // i am getting response

有什么可以帮助我理解这个问题吗?

您必须明确设置extended为,bodyParser.urlencoded()因为默认值将在下一个主要版本中更改body- parser。例子:

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

express4.16.0 开始,您还可以执行以下操作:

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