我正在创建一个wordpress插件，它从我的一个wordpress站点中获取一篇文章，然后将其发布到不同的wordpress站点。出于测试目的，我希望它随机抽取一篇文章，然后每隔30秒抽取一篇文章来创建一篇新文章。

如果没有计划的事件，下面的代码可以正常运行。换句话说，如果我将“create\\u blog\\u post”替换为“activate”，它将能够检测到其他博客帖子，并将创建一个帖子调用“this blog article ready exists”。然而，当我把它放在30秒计时器上时，什么都没有发生。

我尝试了其他方法，如按标题获取页面，并将与计划的事件一起运行。然而，它并没有检测到任何博客帖子，只有页面。

  //activation of plugin
  register_activation_hook( __FILE__,  \'activate\'  );
  //deactivation of plugin
  register_deactivation_hook( __FILE__,  \'deactivate\'  );

    function bgs_add_cron_recurrence_interval( $schedules ) {
        $schedules[\'every_30_seconds\'] = array(
                \'interval\'  => 30,
                \'display\'   => __( \'Every 30 Seconds\', \'textdomain\' )
        );
        return $schedules;
    }
    add_filter( \'cron_schedules\', \'bgs_add_cron_recurrence_interval\' );

    function activate() {
      if ( ! wp_next_scheduled( \'30_second_action\' ) ) {
         wp_schedule_event( time(), \'every_30_seconds\', \'30_second_action\' );
      }
    }
    add_action(\'30_second_action\', \'create_blog_post\');


    function create_blog_post(){
      $jsondata    = file_get_contents(\'http://blog.hansenlighting.com/wp-json/wp/v2/posts?per_page=20\'); //pulls json data from hansenlighting blog
      $json        = json_decode($jsondata,true); //turns json data into something that php can understand
      $ranNum      = rand(1,10); //generates random number between 1-10
      $blogTitle   = $json[$ranNum][title][rendered];
      $blogContent = $json[$ranNum][content][rendered];

      global $wpdb;

      if ( post_exists($blogTitle) ) {
        $page = array( //creates post content
            \'post_title\' => \'this blog article already exists\',
            \'post_content\' => \'this is a test post\',
            \'post_status\' => \'publish\',
            \'post_author\' => 1,
            \'post_type\' => \'post\',
        );
        wp_insert_post( $page ); //creates post
      } else {
        $page = array( //creates post content
            \'post_title\' => $blogTitle,
            \'post_content\' => $blogContent,
            \'post_status\' => \'publish\',
            \'post_author\' => 1,
            \'post_type\' => \'post\',
        );
        wp_insert_post( $page ); //creates post
      }
    }
    function deactivate(){
      //wp_clear_scheduled_hook(\'my_hourly_event\');
      flush_rewrite_rules(); //may not need this since its not a custom post type
    }
    function uninstall(){
