body: <p>$doc has a link. for example </p>
  
  <pre><code>$doc = /storage/source/logo.jpg
  </code></pre>
  
  <p>I have a view like this below.</p>
  
  <pre><code>&lt;a class="dropdown-item" href="{{url('admin/download/take')}}/{{$doc}}"&gt;{{$doc}}&lt;/a&gt;
  </code></pre>
  
  <p>i have this route below</p>
  
  <pre><code>Route::get('download/take/{link})','IncomingController@getGo');
  </code></pre>
  
  <p>and this is my function</p>
  
  <pre><code>    public function getGo(Request $request, $link){
      print_r($link);
