我已经使用Docker Toolbox和Docker Quickstart Terminal在docker上设置了启动画面。它给出了这个输出：

我按照Splash指南的说明进行操作：
Splash UI提供了一种简单的尝试脚本的方法：Lua的代码编辑器和提交脚本以执行的按钮。访问http://127.0.0.1:8050/（或Splash正在收听的任何主机/端口）。
但我无法打开地址。从日志中：

由于奇怪的格式，我无法识别日志记录的时间。有人能说出没有打开启动UI的问题在哪里？
我找到了一个解决方案，我在这里报告因为该指南对初学者来说有点误导......它暗示：
Splash UI提供了一种简单的尝试脚本的方法：Lua的代码编辑器和提交脚本以执行的按钮。访问http://127.0.0.1:8050/（或Splash正在收听的任何主机/端口）。
一个不了解Docker的人可能会认为它默认情况下可以在127.0.0.1获得。事实上，作为一个虚拟机，它有适当的IP地址，可能与localhost不同。因此，您必须插入XX.XX.XX.XX：端口，将XX替换为vm的正确位置以及您已设置的端口。
