我有一个简单的函数，它返回具有给定pageID的页面内容：

function get_page_content(){

    $id = $_REQUEST[\'id\'];

    $page_data = get_page($id);

      echo apply_filters(\'the_content\', $page_data->post_content);
    //echo do_shortcode($page_data -> post_content);
    wp_die();
}
add_action( \'wp_ajax_nopriv_get_page_content\', \'get_page_content\' );
add_action( \'wp_ajax_get_page_content\', \'get_page_content\' );

但在更新WP和一些插件后，返回的内容仍然包含以下未解决的短代码：

[vc_row row_type=“row“ use_row_as_full_screen_section=“no“ type=“grid“ text_align=“left“ background_image_as_pattern=“without_pattern“][vc_column width=“1/1″]

这些短代码来自一个名为Visual Composer （在此过程中更新至最新版本）

Question:在返回内容之前，如何呈现短代码？我两个都试过了

echo apply_filters(\'the_content\', $page_data->post_content);

以及

echo do_shortcode($page_data -> post_content);

function get_page_content(){

    $id = $_REQUEST[\'id\'];

    $page_data = get_page($id);

    WPBMap::addAllMappedShortcodes();

    echo apply_filters(\'the_content\', $page_data->post_content);
    wp_die();
}
add_action( \'wp_ajax_nopriv_get_page_content\', \'get_page_content\' );
add_action( \'wp_ajax_get_page_content\', \'get_page_content\' );

function get_page_content(){
    global $post;

    $id = $_REQUEST[\'id\'];

    $post = get_page($id);
    setup_postdata($post);
      echo apply_filters(\'the_content\', $post->post_content);
    //echo do_shortcode($page_data -> post_content);
    wp_die();
}
add_action( \'wp_ajax_nopriv_get_page_content\', \'get_page_content\' );
add_action( \'wp_ajax_get_page_content\', \'get_page_content\' );
