i Ajax für das gerade versucht, aber es nicht

@include('partials.navbar')

<link rel="stylesheet" type="text/css" href="http://localhost:8000/assets/css/search.css">

      var dload = JSON.parse(msg)[0];

}); 

mein Controller:

public function dloadFile($id) 
    { 
     $files = Files::where('id',$id) 
        ->get(); 
     return json_encode($files); 
    } 

    public function getDownload() 
    { 
     $id = Input::get('id'); 
     $files = Files::where('id',$id) 
        ->first(); 
     $ftype = $files->file_type = Input::get('type'); 
     $filename = $files->upload = Input::file('filename'); 
     $file= public_path(). "uploads/{$ftype}"; 

     $headers = array(
       'Content-Type: => application/pdf', 
      ); 

     return Response::download($file, '{$filename}', $headers); 


    } 

meine Route:

Route::get('/downloadfile/{id}', 'FileController@dloadFile'); 
Route::get('/download', array('uses' => 'FileController@getDownload')); 

Jede Idee wird viel mehr geschätzt Vielen Dank im Voraus !.

Answer 1

es gibt keine Notwendigkeit, Ajax zum Download zu verwenden. Es gibt meinen Code, um Produktbild herunterzuladen. In der Ansichtsdatei gibt es einen Downloadlink.

<a data-id="{{ $product->id }}" href="/productCRUD/{{$product->id}}/download" class="btn btn-primary btn-xs dload-button" ><i class="fa fa-download">Download</i></a> 

in routes.php

Route::get('productCRUD/{product}/download', 'ProductCRUDController@download'); 

in productCRUDController.php

public function download($id) 
{ 

    $files = Product::where('id',$id) 
       ->first(); 
    $ftype = $files->file_type = Input::get('type'); 
    $fullPath= public_path(). "/uploads/{$files->filePath}"; 
    $headers = array(
      'Content-Type: => application/jpg', 
     ); 
    return Response::download($fullPath,$files->filePath, $headers); 

} 

mit diesem Code, wenn Sie Download-Link klicken Sie die Datei in Ihrem Download-Ordner erhalten.
