我已经找到了解决方案

$current_user = wp_get_current_user();
$userID       = $current_user->ID;

  $args =array( \'author\' => $userID,\'post_type\' => \'custom_post\' ) ;
  $authors_posts = get_posts($args);


    foreach ( $authors_posts as $authors_post ) {
        $content= $authors_post->post_title;
    }

echo $content;
