This module is 'request <https://github.com/mikeal/request>

I think i'm following every step but i'm missing an argument.. 

```
var request = require('request');
request.post({
        url: 'http://localhost/test2.php',
         body: "mes=heydude"
         }, function(error, response, body){
            console.log(body);
    });

```

on the other end i have 

```
echo $_POST['mes'];

```

And i know the php isn't wrong...
