您可以挂接到输出并在那里修改URL。

add_filter( \'post_thumbnail_html\', \'my_post_image_html\', 10, 5 );

function my_post_image_html( $html, $post_id, $post_thumbnail_id, $size, $attr ) {

  $upload_dir = wp_upload_dir();
  $base_url = $upload_dir[\'baseurl\'];

  // Change the default upload directory to AWS Bucket link
  $AWSBucket = \'http://s3.amazonaws.com/bucket\';
  $html = str_replace($base_url, $AWSBucket, $html);

  return $html;
}

输出图像

echo get_the_post_thumbnail ();

然后，您必须将uploads文件夹指向相同的位置。您可以通过在wp-config.php 文件

打开wp配置。php文件，位于WordPress安装的根目录下，并添加以下代码：

define(\'UPLOADS\', \'http://amazon_url/uploads\'); //Replace the url here with folder in Amazon

codex规定，应该将其添加到表示require\\u once（ABSPATH.wp-settings.php）的行之前；。

确保uploads folder is writable.
