nodejs/express获取发布的数据

如何从我的api中获取发布的数据。我正在使用快递3.4.4

我正在做一个resful api，使用node js和express 接受发布的数据

exports.mypost = function(req, res) {
    console.log(req.body);
    console.log(req.body.username);
    console.log(req.body.name);
    var user = new UserInfo({name:"dsd", username:"dsdsds"})
    user.save();
    res.send("user created");
}

我使用发布数据

 curl --data "username=dsds&name=dsd" http://localhost:3000/mypost

我可以看到打印

{ username: 'dsds', name: 'dsd' }
dsds
dsd

但是如果我使用

 curl --form "username=dsds&name=dsd" http://localhost:3000/mypost

我看到

{}
undefined
undefined

这意味着我没有从中获取用户名和名称

req.body

如何从获取数据

 curl --form "username=dsds&name=dsd" http://localhost:3000/mypost

我正在发布我的app.js:

/**
 * Module dependencies.
 */
var express = require('express');
var routes = require('./routes');
var user = require('./routes/user');
var http = require('http');
var path = require('path');
var express = require('express');
var mongoose = require('mongoose');
var app = express();
// all environments
app.set('port', process.env.PORT || 3000);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.json());
app.use(express.urlencoded());
app.use(express.methodOverride());
app.use(express.cookieParser('your secret here'));
app.use(express.session());
app.use(app.router);
app.use(require('stylus').middleware(path.join(__dirname, 'public')));
app.use(express.static(path.join(__dirname, 'public')));
app.use(express.bodyParser());
mongoose.connect('mongodb://localhost/data');
// development only
if ('development' == app.get('env')) {
  app.use(express.errorHandler());
}
app.get('/', routes.index);
app.get('/users', user.list);

var api = require('./controllers/api.js');
app.post('/mypost', api.mypost);
http.createServer(app).listen(app.get('port'), function(){
  console.log('Express server listening on port ' + app.get('port'));
});
