Windows主机无法访问在虚拟框中运行的烧瓶服务器

Question

我尝试从host ='0.0.0.0'运行它，但仍然无法访问。 我可以从虚拟机ping我的Windows机器IP 192.168.1.109，但不能从Windows端从ifconfig 10.0.2.15 ping我的Ubuntu VirtualMachine ip。 如果有帮助，我正在使用virtualbox。

运行

#!flask/bin/python
from app import app
app.run(host='0.0.0.0',port=5000, debug=True)

初始化 .py

当我在主界面中更改此行时，它对我有用

app.run()

至

app.run(host='192.168.163.128', port=5000)

Answer 2

您必须重新配置来宾，使其可以获取自己的IP地址：

步骤 ：

1. 关闭来宾计算机。
2. 在来宾的VirtualBox设置中，选择“网络”，然后将网络适配器类型切换为“桥接”。
3. 重新启动来宾。
4. 做完了
