    请注意,当调用wp_get_attachment_metadata()时,从“file”返回的数组索引是相对于 wp-content/uploads 的文件路径。

    若你们想链接域名的url,可以使用下面的代码段

    $upload_dir = wp_upload_dir();
    $attachment_metadata = wp_get_attachment_metadata( $attachment_id );
    echo var_dump( $upload_dir['url'] . '/' . $attachment_metadata['sizes']['medium_large']['file'] );
