golang chromeDp 使用

借助谷歌开发者工具协议（CDP，Chrome DevTools Protocol）远程与浏览器交互

在Go中实现了Chrome DevTools协议的知名第三方库是 chromedp

linux 界面搭建 chromeDp 环境

docker-compose 搭建 headless-shell

version: '3.1'
services:
  chrome:
    image: chromedp/headless-shell:latest
    ports:
      - "9222:9222"

获取信息

curl localhost:9222/json/version
{
   "Browser": "Chrome/114.0.5735.199",
   "Protocol-Version": "1.3",
   "User-Agent": "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.5735.199 Safari/537.36",
   "V8-Version": "11.4.183.25",
   "WebKit-Version": "537.36 (@581ada08cf738a4eb44f712c6f8cd40030e5c1a0)",
   "webSocketDebuggerUrl": "ws://localhost:9222/devtools/browser/5b3453d9-d437-4d7d-8f23-633d10b96a15"
}

golang 使用

func main() {
    // arg : ws://url:9222/

    c, cancel := chromedp.NewRemoteAllocator(context.Background(), os.Args[1])
    defer cancel()

    ctx, cancel2 := chromedp.NewContext(c)
    defer cancel2()

    ... // logic
}
