学习express之实现Json的Post请求

1）引入模块body-parser

var bodyParser = require(‘body-parser‘);

// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({extended: false}));

// parse application/json
app.use(bodyParser.json());

2）post方法

router.post(‘/group‘, function(req, res, next) {
    console.log(‘post group redpack‘);
    console.log(req.headers[‘content-type‘])
    res.send(req.body);
});

3）注意事项

**bodyParser模块，应放在路由之前

var bodyParser = require(‘body-parser‘);

// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({extended: false}));

// parse application/json
app.use(bodyParser.json()); 

...

app.use(‘/‘, routes);
app.use(‘/app‘, apps);
