title: Laravel Request doesn't have parameters
body: <p>I have a route like this:</p>
  
  <pre><code>Route::get('page/{id},{time}', 'OpController@op');
  </code></pre>
  
  <p>Now my method is simply:</p>
  
  <pre><code>public function op(Request $request, $id, $time)
  {
  
          dump($request-&gt;all());
          dump($id);
  }
  </code></pre>
  
  <p>If I call that with <code>/op/hello,123</code> I get this dump:</p>
  
  <pre><code>$request-&gt;all() -&gt; []
  $id -&gt; "hello"
  </code></pre>
  
  <p>Is there any reasons that <code>$request</code> doesn't have the parameters?</p>
  
  <p><code>$request-&gt;input('id')</code> returns <code>null</code></p>
