下载的文件在S3中显示零字节

Question

我已经完全允许该文件。并从php代码下载...以这种方式......

 while (ob_get_level() > 0) {
  ob_end_clean();
}
header("Content-Disposition: attachment; filename=" . urlencode(basename($filepath)), true);
header("Content-Transfer-Encoding: Binary", true);
header("Content-Type: application/force-download", true);
header("Content-Type: application/octet-stream", true);
header("Content-Type: application/download", true);
header("Content-Description: File Transfer", true);
header("Content-Length: " . filesize($filepath), true);
flush();

$fp = fopen($filepath, "r");
while (!feof($fp)) {
  echo fread($fp, 65536);
  // ob_clean();
  flush();
}
fclose($fp);    

但下载的文件显示zerobytes.Im无法得到完美的答案，你可以帮忙
