我用 Selenium 制作了一个容器图像。我用了ubi image来自 RedHat 作为基础镜像。
我安装了以下版本的 geckodriver 和 Mozilla Firefox
我可以在 Firefox 上成功运行 Selenium 测试。当我运行 headless 测试时，出现了问题:

这些壁虎驱动程序不支持 Mozilla Firefox 68.9.0esr 吗？或者可能是因为 headless 模式不起作用的另一个原因？
最佳答案
此错误消息...
selenium.common.exceptions.WebDriverException: Message: <html><body><h1>504 Gateway Time-out</h1>
The server didn't respond in time.
504 Gateway Timeout 错误是不确定的，因为它们表明您的网站发生了什么，但它们并没有传达到底出了什么问题，因此很难分析根本原因并解决问题。但是，错误 504 Gateway Time-out 背后的原因可能有很多。解决该问题的几种方法如下:
这个用例
但是，在此用例中，此错误消息...
1593770085639 geckodriver::marionette DEBUG Waiting 60s to connect to browser on 127.0.0.1:34835

解决方案
根据 comment在讨论中(firefox:28877): GConf-WARNING **: Client failed to connect to the D-BUS daemon: Address does not contain a colon解决方案是恢复到以前版本的 Firefox ESR 构建。
关于python - 在 GeckoDriver Selenium 和 Python 的 headless 模式下使用 Firefox 68.9.0esr 时出现 504 网关超时错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/64070220/
