在Laravel 5.1中，当我发送标题Content-type来下载文件时，我是否必须将die（）放在最后？

Question

This is my helper

function fileDownload(EloquentFile $file, bool $stream): bool {

    $file_dir = $file->dir . '/';
    $file_url = $file_dir . $file->id;

    $stream = $stream === true ? 'attachment' : 'inline';

    if (Storage::disk('s3')->has($file_url)) {
        header('Content-type: ' . $file->mime);
        header('Content-Disposition: ' . $stream . '; filename=' . $file->name);
        header('Content-Length: ' . $file->size);
        echo Storage::disk('s3')->get($file_url);

        //die(); do I have to put die here?
    }

    abort(404);
}

Question - does commented die() is required here or can I skip it?

Answer 1

I would suggest against using any die or exit statements and just directly return the response.

For your example it would be

return Storage::disk('s3')->get($file_url);
