Php 使用Response:：download（）从AWS S3下载文件

给我：

未处理的异常

信息：

filesize[function.filesize]：stat在解决方案：/laravel/response.php中失败

您不能在aws文件上使用File:：size，因为File:：size===filesize，并且无论出于何种原因，该函数都无法绘制S3文件的图形

public function get_download($record_id)
{
    $record = Record::find($record_id);
    $file_name = $record->with_value('File Upload')->name;

    // something like https://s3.amazonaws.com/webapp/uploads/laravelsauce.png
    $file_url = read_file($record->with_value('File Upload')->value);

    return Response::download($file_url, $file_name);

    /*
    // works but why not the above
    header('Content-Type: application/octet-stream');
    header("Content-Transfer-Encoding: Binary");
    header("Content-disposition: attachment; filename='{$file_name}'");
    readfile($file_url);
    exit;
    */
}
