title: req.params is not a function
body: <p>my api url:</p>
  
  <pre><code>{{url}}/api/v1/users/updateHome?access_token={{access_token}}
  </code></pre>
  
  <p>I am trying to access the property <code>access_token</code>. I have tried the following ways to access it but it returns error:</p>
  
  <ol>
  <li><code>req.params('access_token'); //returns req.params is not a function</code></li>
  <li><code>req.params.access_token; //returns undefined</code></li>
  </ol>
  
  <p>Since <code>req.param('access_token')</code> which works but now deprecated, how can I access the property <code>access_token</code> ?</p>
