H5的WebSocket 怎么和服务端建立连接,网上找了几个例子都不好使,具体应该怎么做
个人理解的是
1、了解websocket的协议和请求规范;
2、使用PHP的socket函数库来处理websocket的请求;
3、处理websocket的数据帧。
下面是我写的一个小例子,里面的注释我觉得也挺详细的了,对帧的处理我没有完善,处理41字节以上的内容,要了解各种字处理。。。待补。

弄明白这些基本的应该能简单的应用了,但是要是用在项目中,还是建议用已经成熟的扩展类workerman或swoole。
使用的话,这要看你的服务器配置了,
服务器端:$ws=new WebSocket("127.0.0.1","8080");
客户端:var ws = new WebSocket("ws://127.0.0.1:8080");
照这么看的话,放在哪里都是无所谓的。。。运行时先用一个窗口运行服务器端,保持监听,然后用另一个窗口运行客户端连接。
我这个是简单版,消息推送弄得跟HTTP响应一样。。。应答没有再次转发,直接服务器返回的,但原理都是一样的。
你需要一个websocket 的服务,可以使用 workman 或者swoole作为websocket服务。
用传统lnmp实现socket不现实。
我都是用node做服务

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.

Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
