前言
本文纯属经验备注，有许多地方未进行测试，请勿照搬，仅供参考。
之前专门花了几天时间测试了websocket，当时只记得踩了许多坑，但是没有对测试流程进行记录，导致长时间未使用从而无从下手。
今天就简单记录一下使用流程。
环境介绍
流程
1、安装长连接框架：composer require workerman/gateway-worker
2、配置基本参数
配置为文件为 config/gateway_worker.php（必须使用对应命令才能启动）
配置端口startPort，pingData，eventHandler，其它默认就好
eventHandler配置为app\index\logic\events\Events.php类，用于处理监听后的业务逻辑
3、启动服务
启动命令为：php think worker:gateway
4、 nginx服务配置以支持/wss方式访问
参考配置：
location /wss
{
proxy_pass http://127.0.0.1:2000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
proxy_set_header X-Real-IP $remote_addr;
}
5、JavaScript客户端建立连接并访问
ws = new WebSocket("wss://boomim.playone.cn/wss");//这种访问方式需要nginx配置
ws.onopen = function() {
alert("连接成功");
ws.send('hello,thinkphp');
alert("给服务端发送一个字符串：hello,thinkphp");
详细配置参考(gateway_worker.php)
