node js / express 获取发布的数据

Question

如何从我的 api 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 来接受使用节点 js 发布的数据并表达

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");
}

我发布数据使用

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

我可以看到指纹

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

但是如果我使用

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

我明白了

{}
undefined
undefined

这意味着我没有从中获取用户名和名称

req.body

我如何从

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'));
});

Answer 1

添加这个：

App.use(express.bodyParser());

确保在所有路线之前设置它。

Answer 2

您可以使用 bodyParser 方法从 post 请求中获取数据

// Configure server
app.configure(function() {
app.use(express.bodyParser());
}
