我试图从图库中检索URL，而不是整个图像对象。我被困住了，因为我要么只能通过以下方式获得全尺寸的图像：

wp_get_attachment_url

因为它不接受任何参数，或者img 通过以下方式标记各种内容：

wp_get_attachment_image

有没有办法获取URL？我现在的代码如下所示：

<?php
    $query_images_args = array(
                               \'post_type\' => \'attachment\',
                               \'post_mime_type\' => \'image\',
                               \'post_status\' => \'inherit\',
                               \'posts_per_page\' => -1,);

    $query_images = new WP_Query( $query_images_args );

    class image {
        public $thumbnail_url;
        public $full_url;
    }
    $images = array();
    foreach ( $query_images->posts as $picture ) {
        $image = new image();
        $image->thumbnail_url = wp_get_attachment_image( $picture->ID, \'thumbnail\' );
        $image->full_url = wp_get_attachment_image( $picture->ID, \'full\' );
        array_push($images, $image);
    }

    foreach($images as $image) {
        $thumbnail_url = $image->thumbnail_url;
        $full_url = $image->full_url;
?>

我希望能够正确填写：

<li><img data-full-url="<?php echo $full_url ?>" src="<?php echo $thumbnail_url; ?>" /></li>

   $thumbnail_src = wp_get_attachment_image_src( $picture->ID );
   $image->thumbnail_url = $thumbnail_src[0];
   $full_src = wp_get_attachment_image_src( $picture->ID, \'full\' );
   $image->full_url = $full_src[0];
