无法从Windows主机访问在虚拟框中运行的flask服务器

Question

我尝试从host ='0.0.0.0'运行它，但它仍然无法访问。我可以从我的虚拟机中ping我的Windows机器ip 192.168.1.109，但我无法从我的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。

run.py

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

当我在主界面中更改此行时，它对我有用

app.run()

到

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

Answer 2

您必须重新配置来宾，以便它可以获得自己的IP地址：

<强>步骤：

  

  
1. 关闭来宾计算机。
  
2. 在来宾的VirtualBox设置中，选择“网络”并切换网络   适配器类型为“Bridged”。
  
3. 重新启动来宾。
  
4. 完成。
