使用端口模式启动浏览器
找到chromium安装位置，默认位置如下
C:\Users\user\AppData\Local\pyppeteer\pyppeteer\local-chromium\588429\chrome-win32
cmd 执行chrome.exe --disable-infobars --remote-debugging-port=9222
在打开的chromium 浏览器输入http://localhost:9222/json查看连接信息
[ {
"description": "",
"devtoolsFrontendUrl": "/devtools/inspector.html?ws=localhost:9222/devtools/page/6CB00490AAA1F35C7B5BCBE39D487B6B",
"id": "6CB00490AAA1F35C7B5BCBE39D487B6B",
"title": "随时随地使用 Chromium",
"type": "page",
"url": "http://localhost:9222/json",
"webSocketDebuggerUrl": "ws://localhost:9222/devtools/page/6CB00490AAA1F35C7B5BCBE39D487B6B"
} ]
webSocketDebuggerUrl就是要在程序中连接的地址（即下方测试demo中的连接参数browserWSEndpoint）
