如何使用Datatables Yajra在Laravel上下载文件

composer require yajra/laravel-datatables-oracle

Yajra\DataTables\DataTablesServiceProvider::class,

'DataTables' => Yajra\DataTables\Facades\DataTables::class,

php artisan vendor:publish --provider="Yajra\DataTables\DataTablesServiceProvider"

php artisan make:datatable FilesDataTable --model=App\Models\File

namespace App\DataTables;

use App\Models\File;
use Yajra\DataTables\Services\DataTable;

class FilesDataTable extends DataTable
{
    public function dataTable($query)
    {
        return datatables()
            ->eloquent($query)
            ->addColumn('download', function ($file) {
                return '<a href="' . route('files.download', $file->id) . '">Download</a>';
            });
    }

    public function query(File $model)
    {
        return $model->newQuery();
    }

    public function html()
    {
        return $this->builder()
            ->columns($this->getColumns())
            ->parameters([
                'dom' => 'Bfrtip',
                'buttons' => ['csv', 'excel', 'pdf'],
            ]);
    }

    protected function getColumns()
    {
        return [
            'id',
            'name',
            'size',
            'created_at',
            'updated_at',
            'download',
        ];
    }
}

Route::get('files/{file}/download', 'FileController@download')->name('files.download');

php artisan make:controller FileController

namespace App\Http\Controllers;

use App\Models\File;
use Illuminate\Support\Facades\Storage;

class FileController extends Controller
{
    public function download(File $file)
    {
        $path = Storage::disk('public')->path($file->path);
        return response()->download($path, $file->name);
    }
}

namespace App\Http\Controllers;

use App\DataTables\FilesDataTable;
use App\Models\File;

class HomeController extends Controller
{
    public function index(FilesDataTable $dataTable)
    {
        return $dataTable->render('files.index');
    }
}
