Question

当我第一次调用此函数然后文件已下载但刷新页面后，它显示我的浏览器屏幕上有一些不理解的字符

    // Controller Code

     public function actionDownload($id)
       {
                $model = $this->findModel($id);
                $file ='../frontend/uploads/users/'.$model->image;

                if(file_exists($file))
                {
                 return Yii::$app->response->sendFile($file);
                 exit;
                }

    //Button Code
[
             'attribute'=>'resume',
             'label'=>'Resume',
             'format'=>'raw',
             'value'=>function($data)
             {
                   if($data->resume != null)
                   {
//                      $url = Yii::$app->params['application_base'].'admin/user/download/'.$data->id;
                      return Html::a('Download', ['download','id'=> $data->id]);
                   }
                   else
                   {
                      return 'NA';
                   }
             },

            ],

Answer 1

尝试省略pjax amd use

return Html::a('Download', ['download','id'=> $data->id, 'data-pjax' => 0]);

而不是

return Html::a('Download', ['download','id'=> $data->id]);

Yii2文件下载错误
