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…
cmd
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:
extended
bodyParser.urlencoded()
body- parser
app.use(bodyParser.urlencoded({ extended: true }));
从express4.16.0 开始,您还可以执行以下操作:
express
app.use(express.urlencoded({ extended: true }))
