如何下载安全镜像

Question

我正在尝试下载一个安全的图像，我可以下载除以下链接以外的其他图像。

https://store.bbcomcdn.com/images/store/skuimage/sku_EVL4900077/image_skuEVL4900077_largeImage_X_450_white.jpg

下面是我的代码：

<?php
    function downloadFile ($url, $path) {

  $newfname = $path;
  $file = fopen ($url, "rb");
  if ($file) {
    $newf = fopen ($newfname, "wb");

    if ($newf)
    while(!feof($file)) {
      fwrite($newf, fread($file, 1024 * 8 ), 1024 * 8 );
    }
  }

  if ($file) {
    fclose($file);
  }

  if ($newf) {
    fclose($newf);
  }
 }

downloadFile ("https://store.bbcomcdn.com/images/store/skuimage/sku_EVL4900077/image_skuEVL4900077_largeImage_X_450_white.jpg", "name.jpg");
?>
