Express.js req.body 什么都不返回

Question

I am learning node and express to create an api for an angular app I will be creating.

When I try and post something the req.body seems to be blank.

This is my server.js file

'use strict';

var express = require('express'),
  app = express(),
  mongoose = require('mongoose'),
  router = require('./api'),
  bodyParser = require('body-parser');

mongoose.connect('mongodb://localhost/my_db');

app.use(bodyParser.json());
app.use('/api', router);

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

app.listen(3001, function() {
  console.log('Listening on port 3001');
});

and this is my api/index.js file:

'use strict';

var express = require('express'),
    Todo = require('../models/todo'),
    router = express.Router();

router.get('/todos', function(req, res) {
  Todo.find({}, function(err, todos) {
    if(err) {
      return console.log(err);
    }
    res.json({todos: todos});
  });
});

router.post('/todos', function(req, res) {
  var todo = req.body;
  res.json({todo: todo});
});


module.exports = router;

when I use postman to post this to http://localhost:3001/api/todos :

{
    'name': 'Walk the Dog',
    'completed': false
}

my response is:

{
  "todo": {}
}

I can't see why this would be blank, any help is appreciated.

UPDATE

Turns out I was posting text in postman instead of JSON .

use this in your server.js file

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