how to convert $resource to $http?
<p>How can my use of <code>$resource</code> be converted to instead leverage the raw <code>$http</code> service? And what exactly does <code>$resource</code> do that <code>$http</code> does not?</p>

<pre><code>return $resource(API_LINK+'/api/users/', {
   id: '@_id'
 },
 {
   changePassword: {
     method: 'PUT',
     params: {
       controller:'password'
     }
   },
   get: {
     method: 'GET',
     params: {
       id:'me'
     }
   })
</code></pre>
