start_web.php增加ajax功能报错

rikeylin

问题描述

截图
我使用最简版聊天室进行修改,修改start_web.php,增加响应前端ajax功能,响应后依据获取到的id进行数据库读取并反馈结果给前端;很奇怪的问题是:使用守护模式php start.php -d运行后,ajax功能失效,但是如果使用php start.php运行后,ajax功能是正常的;不知道问题出在哪里,请大神帮忙指导下,谢谢!~~~

按照文档数据库初始化放到onWorkerStart里

  • rikeylin 2024-06-17

    好的,我试下看看,谢谢!~~~

  • rikeylin 2024-06-17

    我在Events.php中public static function onWorkerStart($worker)
    {

        self::$db = new \Workerman\MySQL\Connection('127.0.0.1', '3306', 'user', 'pass', 'db');}使用这种方式进行初始化,那我在Start_web.php中调用是不是就采取$result = Events::$db->query("select * from eq where id=".$id);//这种方式进行读取就可以了,但是实际运行不行,报错“Error: Call to a member function query() on null in /var/www/html/Applications/Chat/start_web.php:66”,应该怎么引用?
  • walkor 2024-06-17
    $web->onWorkerStart = function(){
        Events::$db = new \Workerman\MySQL\Connection(...);
    };
  • rikeylin 2024-06-17

    感谢大神!~~~就是要在start_web.php里面采取$web->onWorkerStart = function(){
    Events::$db = new \Workerman\MySQL\Connection(...);
    };这种方式对数据库进行读写才可以,否则对AJAX会造成影响,已解决!~~~
