workerman 怎么实现mysql数据库里面的一个表一旦有新的数据的加入,就把新的数据发送到前端?
我的需求是这样的,使用workerman 来做前后端的长链接,然后mysql的一张表一旦有了新的数据,就把新的数据发送到前端,发送的数据是个数组,我该怎么实现?如果我的描述不够清楚,请再问,本人在线等,谢谢大神帮忙解决了.

可以通过workerman的phpsocket.io推送

可以在Worker中开一个text端口推送

利用workerman的gatewayWorker推送,使用GatewayClient
什么时候触发以及怎么触发需要自己控制
我一般使用redis来解决。
在插入表的地方进行判断,是否需要把数据发送给前端
使用触发器吧,先创建自定义函数,函数会访问你需要回调的程序的端口,然后触发器里面调用该函数----我说的是mysql触发器,mysql diy函数可以直接用c来写,方便又快捷,php装一个多线程模块,监听两个端口,一个用于与前端websocket进行交互,一个用于接收mysql触发器发送过来的数据,可以在数据库中建立一个socketid表用来关联各个线程,其实这种破事用.net会比较好写
可以定时查下数据库,如果有数据,就调workerman的接口发过去
我当年遇到这个需求,需要数据库主动推送数据给应用程序通知,然并未发现啥解决方案,这个要问dba是不是有这种手段,我解决方案当时用的定时任务,轮训的数据库~
另外,数据的录入过程那里能不能给你系统个通知啥的,具体可以聊聊设计
没接触过workerman,代码也写得少,仅仅提供一种思路:
<code>在写入数据 的代码那里加一个 拦截函数,起到通知workerman的作用</code>
这个有个局限性,就是数据库有多个写入口的话,这样就很蛋疼。
尽量不要与mysql结合

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
