科尔多瓦文件传输不会下载没有错误控制台

Question

我正在使用 Framework7 ，并使用laravel 4.2生成pdf文件，但是当我单击按钮时，会在控制台上显示此文件：

下载完成：file：///data/user/0/com.aotour.driver/files/constancia_99469.pdf

但是什么也不要下载

$$('button').click(function(){

  var servicio_id = $$(this).attr('data-id');

  var fileTransfer = new FileTransfer();

  var uri = encodeURI(urlserver+"descargarconstancia/"+servicio_id);

  var fileURL = cordova.file.dataDirectory+'constancia_'+servicio_id+'.pdf';

  fileTransfer.download(
    uri,
    fileURL,
    function(entry) {
      console.log("download complete: " + entry.toURL());
    },
    function(error) {
      console.log("download error source " + error.source);
      console.log("download error target " + error.target);
      console.log("download error code" + error.code);
    },
    false,
    {
      headers: {
          "Authorization": token
      }
    }
  );

});

laravel代码

Route::get('descargarconstancia/{id}', function($id){

  $servicio = Servicio::find($id);

  $pdfName = 'constancia_'.$servicio->id.'.pdf';

  $pdfPath = 'biblioteca_imagenes/constancias/';

  $view = View::make('servicios.plantilla_constancia_vieja')->with(['servicio' => $servicio]);

  $view = preg_replace('/>\s+</', '><', $view);

  File::put($pdfPath.$pdfName, PDF::load($view, 'A4', 'portrait')->output());

  header("Content-type:application/pdf");

  return Response::download($pdfPath.$pdfName);

});
