在 Docker 内执行的 Selenium Grid 不会自动下载文件

Question

我正在尝试部署一个使用 Selenium 从网页下载 PDF 文件的应用程序。如果我在本地运行容器，一个使用 Python 应用程序，另一个使用 Selenium Grid，它会正常工作并在指定目录中自动生成预期的文件。

但是当我在远程服务器内运行同一组容器时，出于部署目的，它会显示一个查找器菜单，要求我确认文件的下载，有人知道如何解决这个问题吗？

更改文件的目录，我正在尝试自动下载文件。

您需要检查卷部分中正确的文件夹映射。

volumes:
      - "/home/user/Downloads:/home/docker-image/downloads"
