title: Why does req.params return an empty array?
body: <p>I'm using Node.js and I want to see all of the parameters that have been posted to my script. To get to my function, in my <code>routes/index.js</code> I'm doing:</p>
  
  <pre><code>app.post('/v1/order', order.create);
  </code></pre>
  
  <p>Then in my function, I have:</p>
  
  <pre><code>exports.create = function(req, res, next) {
   console.log( req.params );
  </code></pre>
  
  <p>But it's returning an empty array. But when I do:</p>
  
  <pre><code>exports.create = function(req, res, next) {
   console.log( req.param('account_id') );
  </code></pre>
  
  <p>I get data. So I'm a bit confused as to what's going on here.</p>
