我只能按单个角色列出用户。当我尝试在下面的代码中添加一个数组时，我只会得到一个所有作者的列表。我肯定我错过了一些直接的东西。

    $wp_user_query = new WP_User_Query($args);
    $wp_user_query->query_orderby = str_replace( \'user_login\', \'lsjs_usermeta.meta_value\', $wp_user_query->query_orderby );
    $wp_user_query->query();

    $authors = $wp_user_query->get_results();
