开箱即用，使用核心可用挂钩和API，you can\'t have more than 100 items per response on WordPress REST API 出于性能原因。对于问题的第二部分，您可以使用_fields 您可以在examples of the handbook:

    // option a: using comma separated fields names.
    https://example.com/wp-json/wp/v2/posts/?_fields=author,id,excerpt,title,link

    // option b: using array syntax.
    https://example.com/wp-json//wp/v2/posts?_fields[]=author&_fields[]=id&_fields[]=excerpt&_fields[]=title&_fields[]=link

if(!function_exists(\'wpse_382314_post_filter_data\')) :
    function wpse_382314_post_filter_data($response, $post) {
        $response->data[\'post_title\'] = \'\';
        $response->data[\'post_content\'] = \'\';
    }
}

add_filter(\'rest_prepare_post\', \'wpse_382314_post_filter_data\', 10, 3);
