此处的“已验证”是指根据is_user_logged_in() 功能，即用户是否登录，无论用户角色如何。

此部分来自admin-ajax.php 文件，解释了所有内容：

if ( is_user_logged_in() ) {
        /**
         * Fires authenticated AJAX actions for logged-in users.
         *
         * The dynamic portion of the hook name, `$_REQUEST[\'action\']`,
         * refers to the name of the AJAX action callback being fired.
         *
         * @since 2.1.0
         */
    do_action( \'wp_ajax_\' . $_REQUEST[\'action\'] );
} else {
        /**
         * Fires non-authenticated AJAX actions for logged-out users.
         *
         * The dynamic portion of the hook name, `$_REQUEST[\'action\']`,
         * refers to the name of the AJAX action callback being fired.
         *
         * @since 2.8.0
         */
    do_action( \'wp_ajax_nopriv_\' . $_REQUEST[\'action\'] );
