Python 从windows浏览器访问ubuntu虚拟机主机

我有一台virtualbox ubuntu机器运行hellow world flask应用程序

我试着让应用程序显示在127.0.0.1:5000和0.0.0.0:5000上

但当我尝试在我的windows浏览器上加载时，这两个问题都无法解决

当我在ubuntu虚拟机中运行ifconfig时，我得到以下信息：

但由于某些原因，当我在windows浏览器中转到192.168.56.1时，它会加载一个白色页面。如果我转到192.168.56.1:5000，它会说它无法连接

在我的虚拟盒子里，我把它“附加到：NAT” 和端口转发规则显示

ssh TCP 127.0.0.1主机端口2222来宾ip为空，来宾端口为22

我的烧瓶应用程序显示

 * Running on http://0.0.0.0:5000/ (Press CTRL+C to quit)
 * Restarting with stat

也试过了

 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
 * Restarting with stat

您可以在VirtualBox文档中找到问题的答案： 6.3.1. 使用NAT配置端口转发

您可以将端口5000从来宾操作系统（Ubuntu）转发到主机操作系统。在主机端，您可以使用相同的端口号（如果它没有被其他人占用，当然）

您可能还需要转发端口5000。@GregHNZ是否有一个默认端口，我也可以更改它？我已经读了几遍，仍然感到困惑。所以我研究了端口转发规则，并建立了一个新的规则，包括端口和ip？你的回答帮助我实现了这一点。非常感谢。我相信你。我需要做的是进入virtualbox中vm的端口转发规则，然后单击端口转发规则设置主机端口为1234，来宾端口为5000。
