这就是我到目前为止所做的，如果有更好的方法我还不知道，我不会把它标记为正确答案。

add_action(\'wp_enqueue_scripts\',array( $this, \'remove_all_actions\'), 99);
public function remove_all_actions(){
        if( \'custom-template.php\' != get_page_template_slug( get_queried_object_id() ))
            return;
        global $wp_scripts, $wp_styles;

        $exceptions = array(
            \'admin-bar\',
            \'jquery\',
            \'query-monitor\'
        );

        foreach( $wp_scripts->queue as $handle ){
            if( in_array($handle, $exceptions))
                continue;
            wp_dequeue_script($handle);
        }

        foreach( $wp_styles->queue as $handle ){
            if( in_array($handle, $exceptions) )
                continue;
            wp_dequeue_style($handle);
        }

        // Now remove actions
        $action_exceptions = array(
            \'wp_print_footer_scripts\',
            \'wp_admin_bar_render\',

        );

        // No core action in header
        remove_all_actions(\'wp_header\');

        global $wp_filter;
        foreach( $wp_filter[\'wp_footer\'] as $priority => $handle ){

            if( in_array( key($handle), $action_exceptions ) )
                continue;
            unset( $wp_filter[\'wp_footer\'][$priority] );
        }

    }
