selenium/standalone-chrome 使用 selenium 4.0.0 return DNS 错误

Question

配置：Python3.10/selenium 3.141.0/selenium/standalone-chrome：最新作品！

但是

当我将 selenium 版本更改为 4.0.0 时：配置：Python3.10/selenium 4.0.0/selenium/standalone-chrome:latest

服务器 return 当我尝试使用 remoteWebDriver 和 selenium 4.0.0 时出现 DNS 错误

Chrome 选项：

opt = Options()
        opt.add_argument('--disable-popup-blocking')
        opt.add_argument('--no-sandbox')
        opt.add_argument("--window-size=1920,1080")
        opt.add_argument("--start-maximized")alse)
        opt.headless = True

RemoteDrvcall:

结果会话未创建且构建失败（仅适用于 selenium 4.0.0）

如有任何想法，我将不胜感激

Answer 1

尝试：

self.wd = webdriver.Remote("http://chrome:4444", options=opt)

而不是

self.wd = webdriver.Remote("http://chrome:4444/wd/hub", options=opt)

他们改变了网格的界面。

Answer 2

谢谢@pcalkins。已在评论中回答

存在issue：selenium 4.0.0 + gitlab

在gitlab-ci.yml重新定义no_export变量

export no_proxy="为 SELENIUM STANDALONE 添加您的别名（例如 chrome）"
```
services:
  - name: selenium/standalone-chrome:98.0
    alias: chrome
```

selenium/standalone-chrome 使用 selenium 4.0.0 return DNS 错误

selenium/standalone-chrome with selenium 4.0.0 return DNS ERROR

dns
