laravel 下载响应文件名不变

Question

我正在使用 laravel 并尝试下载文件并更改文件名。 文档告诉我，我可以使用第二个参数作为新文件名，但文件名不会以某种方式更改为“testdownload.zip”。我做错了什么？

https://laravel.com/docs/5.8/responses#file-downloads

    // routes
    Route::group(['middleware' => ['web']], function()
    {
        Route::group(['namespace' => 'App\Http\Controllers'], function()
        {
            Route::group(['middleware' => ['role:root|admin|store|user']], 
function()
            {
                // download purchase
                Route::get('dashboard/order/downloadfile', [
                    'as'    => 'order-download',
                    'uses'  => 'Post\PostController@download'
                ]);
            });
        }
    }

    // method in Controller
    public function download(Request $request)
    {
        return response()->download(storage_path('app/lorem-ipsum-shop-1.zip'), 'testdownload.zip', ['Content-Type: application/zip']);
    }

当我做 dd(response()->download(storage_path('app/lorem-ipsum-shop-1.zip'), 'testdownload.zip', ['Content-Type: application/zip']) ) 返回以下内容（可能是 perms / 权限 0100666？我在 Windows 上）：

始终清除缓存...我认为它在重命名之前存储了文件名。
