我不知道如何编辑问题，我发现了这样一个问题：但这样我就不能指定我的请求，有没有办法修改这个代码以便我可以指定它？

 function check_api_data() {    
  if(isset($_GET[\'api\']) ) {
  if ($_GET[\'api\'] == \'json\'){
           $args = array(  
               \'post_status\' => \'publish\', 
               \'nopaging\'    => true,
               \'orderby\'     => \'title\',
               \'order\'       => \'ASC\'
           );
           $query = new WP_Query( $args ); // $query is the WP_Query Object
           $posts = $query->get_posts();   // $posts contains the post objects

           $output = array();
           foreach( $posts as $post ) {    // Pluck the id and title attributes
               $output[] = array( 
                \'id\' => $post->ID, 
                \'title\' => $post->post_title, 
                \'content\' => $post ->post_content,
                \'imageurl\' => wp_get_attachment_url( get_post_thumbnail_id($post->ID) )
                );
           }
           echo json_encode( $output );
       }
   exit();
   }  
}
