如何从公共文件夹中获取图像文件作为 Laravel 中的响应？

Question

These are different ways I have tried in my controller to get image as response.

My images resides in public folder/img .

switch ($document->ext) {

    case 'doc':
        $img = File::get(url('/img/doc.png'));
        break;

    case 'docx':
        $img = File::get(asset('/img/docx.jpg'));
        break;

    case 'pdf':
        $img = File::get(public_path('/img/pdf.png'));
        break;

    case 'ppt':
        $img = File::get(url(public_path('/img/ppt.png')));
        break;

    default:
}
return new Response($img, 200);

Answer 1

I guess it is a better way in case we change the public_path

        case 'doc':
        return response()->file(public_path('img/doc.png'));
        exit;

Answer 2

在文件夹名称之前添加 public

$img = File::get(url('public/img/doc.png'));

Answer 3

Use this to download a file from public folder with the option to setting a name

public function downloadSample(){
        return Response::download(public_path("folder/my_file.xlsx"),
                     'your_file_name_when_downloaded.xslx');
    }
