这里有一个编程方法。它的作用是检查ajax请求是否正在运行，以及useragent是否在定义的白名单中，如果在白名单中，它将继续正常加载wp，否则它将死亡。我使用registered\\u分类法，因为它是钩子加载过程中的第二个钩子：

/* Disable AJAX for Spiders */
add_action( \'registered_taxonomy\' , \'disable_ajax_for_spiders\' );

function disable_ajax_for_spiders() {

    if ( !defined(\'DOING_AJAX\') || !DOING_AJAX ) {
        return;
    }

    if ( !isset($_SERVER[\'HTTP_USER_AGENT\']) )  {
        return;
    }

    $visitor_useragent = strtolower($_SERVER[\'HTTP_USER_AGENT\']);

    $useragents[] = \'msie\';
    $useragents[] = \'firefox\';
    $useragents[] = \'webkit\';
    $useragents[] = \'opera\';
    $useragents[] = \'netscape\';
    $useragents[] = \'konqueror\';
    $useragents[] = \'gecko\';
    $useragents[] = \'chrome\';
    $useragents[] = \'songbird\';
    $useragents[] = \'seamonkey\';
    $useragents[] = \'flock\';
    $useragents[] = \'AppleWebKit\';
    $useragents[] = \'Android\';
    $useragents[] = \'Lynx\';
    $useragents[] = \'Dillo\';

    /* If useragent in list then bail - else die() immediately*/ 
    if ($visitor_useragent)
    {
        foreach ($useragents as $k=>$useragent)
        {
            $useragent = trim($useragent);
            if ($useragent)
            {
                if(stristr($visitor_useragent, $useragent)||$useragent==\'*\')
                {
                    return;
                }
            }
        }
    }

    die();
}
