有两个函数可以根据彼此获取不同的附件参数，但粗略看一下并不能表明有一个函数可以根据附件页面URL获取附件参数。

您可以尝试使用$wpdb 类，然后将该ID放入wp_get_attachment_image_src() 作用像这样的事情会让你开始：

function get_attachment_id_by_url( $url ){
    global $wpdb;

    $url   = trim( $url, \' /\' ); // Trim whitespace and trailing slash
    $parts = explode( \'/\', $url ); 
    $name  = end( $parts ); // We only want the last part

    if( ! $result = $wpdb->get_row( $wpdb->prepare( "SELECT ID FROM $wpdb->posts WHERE post_name = %s", $name ) ) ) // potentially replace post_name with post_title
        return false;

    return $result->ID;
}

// Attachment URL we want to utilize
$image_url = \'https://example.com/attachment/name_of_photo/\';

// Get the ID using our function above
$image_id  = get_attachment_id_by_url( $image_url );

// Get the SRC parameters from that ID (use whatever `$size` args you want)
$image_src = wp_get_attachment_image_src( $image_url, \'full\' );

/**
 * var_dump($image_src) Output:
 * 
 * array(4) {
 *    [0]=> string(48) "https://example.com/attachment/name_of_photo.png"
 *    [1]=> int(640)
 *    [2]=> int(480)
 *    [3]=> bool(true)
 * }
