浏览器cdp协议-通过在命令中指定 sessionId 属性，实现对会话的“平面”访问-只连接一次ws客户端

浏览器cdp协议-通过在命令中指定 sessionId 属性，实现对会话的“平面”访问

1.指定端口启动浏览器，如"C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" --remote-debugging-port=9333，可以自己设置一下，这样打开的浏览器才可以连接成功，端口设置为了--9333---

2.获取浏览器主程序的ws网址  如：http://localhost:9333/json/version ------》   
"webSocketDebuggerUrl": "ws://localhost:9333/devtools/browser/2ef636d7-05f1-48c8-a786-f4c2c16cd9b1" 

{
   "Browser": "Edg/144.0.3719.82",
   "Protocol-Version": "1.3",
   "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/144.0.0.0 Safari/537.36 Edg/144.0.0.0",
   "V8-Version": "14.4.24.5",
   "WebKit-Version": "537.36 (@f6f6e1fcd9e657331ac288db133ef45210223f60)",
   "webSocketDebuggerUrl": "ws://localhost:9333/devtools/browser/2ef636d7-05f1-48c8-a786-f4c2c16cd9b1"
}

3.通过ws客户端连接浏览器服务端=》ws://localhost:9333/devtools/browser/2ef636d7-05f1-48c8-a786-f4c2c16cd9b1
