title: Request body in express is undefined?
body: <p>I am making a simple POST request using Alamofire (in iOS) and handling it in node using express. 
  My code in iOS: </p>
  
  <pre><code>    let boop: [String: AnyObject] = ["username":"fakeuser"];
  Alamofire.request(.POST,"http://localhost:3000/test", parameters: boop, encoding: .JSON)
  </code></pre>
  
  <p>And this is my code in node:</p>
  
  <pre><code>    var app = require('express')();  
  var http = require('http').Server(app);  
  app.post('/test', function(req, res){
   console.log("THE SERVER HAS RECEIVED THE POST! \n")
   console.log(req.body);
  });
  
  http.listen(PORT, function(){
    console.log('listening on *:3000');
  });
  </code></pre>
  
  <p>My terminal console prints out "the server has received the post" , so I know that the post is actually triggered. The issue is that instead of logging the req.body, it instead prints out "undefined". I've looked around and it seems like a "body parser" thing needs to be configured but apparently that is obsolete with the new version of express. So I am lost as to what to do. </p>
  
  <p>Any advice?</p>
