我找到丢失的内容（$wp\\u query->queryed\\u object\\u id；），答案如下：

$current_browsing_author = $wp_query->queried_object_id; // Get current browsing author
$sticky = get_option( \'sticky_posts\' ); 
rsort( $sticky ); 
$sticky = array_slice( $sticky, 0, 5000 );
query_posts( array(
\'post__in\' => $sticky,
\'author\' => $author,
\'orderby\' => \'rand\',
\'post_type\' => \'post\',
\'post_status\' => \'publish\', 
\'posts_per_page\' => 5,
\'caller_get_posts\'=> 5
) );
