Question

Without router middleware, once the server side receive the post data, it could log it normally:

var express = require('express');
var app = express.createServer();
app.configure(function () {
    app.use(express.static(__dirname + '/static'));
    // app.use(app.router);
    app.use(express.bodyParser());
})

app.get('/', function(req, res){
    res.send('Hello World');
});

app.post('/', function(req, res){
    console.log('body:', req.body);
    res.send(req.body);
});

app.listen(8000);

But once I use the router middleware, the log result is undefined and response nothing

Why? How can I solve this problem?

Answer 1

The problem is the order you called router

bodyParser must be called before router

app.configure(function () {
  app.use(express.static(__dirname + '/static'));
  app.use(express.bodyParser());
  app.use(app.router);
});
