Splash UI 未在 windows 开始
Splash UI doesn't start on windows
我已经使用 Docker 工具箱和 Docker 快速启动终端在 docker 上设置了 splash。它给出了这个输出：
$ docker run -p 8050:8050 scrapinghub/splash

Splash UI provides an easy way to try scripts: there is a code editor for Lua and a button to submit a script to execute. Visit http://127.0.0.1:8050/ (or whatever host/port Splash is listening to).
但是我打不开地址。

由于格式奇怪，我无法识别记录的时间。谁能告诉我打不开 splash 的问题出在哪里 UI?
我找到了一个解决方案，我在这里报告是因为该指南对初学者的误导性很小...
它建议：
Splash UI provides an easy way to try scripts: there is a code editor for Lua and a button to submit a script to execute. Visit http://127.0.0.1:8050/ (or whatever host/port Splash is listening to).
不了解 Docker 的人可能会认为它在默认情况下可在 127.0.0.1 访问。事实上，作为一个虚拟机，它有自己的 IP 地址，可能与 localhost 不同。因此，您必须改为插入 XX.XX.XX.XX:port，将虚拟机的正确位置和您设置的端口替换为 XX。
