Node/Express - bodyParser empty for PUT requests

Question

I'm getting an error with Express in bodyParser is failing to parse any PUT requests... my config is set up like so:

 app.use(express.bodyParser());
 app.use(express.methodOverride());
 app.use(express.query());
 app.use(app.router);

However everytime I make a PUT request to an endpoint, req.body returns as 'undefined'.

I've tried making request through Chromes REST console, and also via jQuery ajax requests like so:

 $.ajax({
     url: 'https://localhost:4430/api/locations/5095595b3d3b7b10e9f16cc1',
     type: 'PUT',
     data: {name: "Test name"},
     dataType: 'json'
 });

Any ideas?

You also need to set the Content-Type to application/json. Your jQuery request should be:

$.ajax({
     url: 'https://localhost:4430/api/locations/5095595b3d3b7b10e9f16cc1',
     type: 'PUT',
     contentType: 'application/json',
     data: JSON.stringify({name: "Test name"}),
     dataType: 'json'
 });

Otherwise, the body parser won't attempt to parse the body.

EDIT: here is my test code

1. Run express test

2. Add a /test route in app.js:

app.all('/test', routes.test);

and routes/index.js:

exports.test = function (req, res) {
  console.log(req.body);
  res.send({status: 'ok'});
};

1. Link jQuery and the following script in index.jade:

$(function () {
  $('#test').click(function () {
    $.ajax({
      url: '/test',
      type: 'PUT',
      contentType: 'application/json',
      data: JSON.stringify({name: "Test name"}),
      dataType: 'json'
    });
  });
});

When I run this, I get the following log:

Express server listening on port 3000
GET / 200 26ms - 333
GET /stylesheets/style.css 304 2ms
GET /javascripts/test.js 304 1ms
{ name: 'Test name' }
PUT /test 200 2ms - 20
