无法使用 vs 代码连接到容器中的 django 进程运行

Question

我无法连接到使用 vs-code 生成的容器内的 django 进程运行。一切似乎都在工作，我收到了服务器的启动消息，但是当连接到 localhost:8000 时，我没有收到任何响应...

我在启动容器时收到已发布的端口消息：

Published Ports: 8000/tcp -> 127.0.0.1:8000

并且在启动 launch.json 调试时也是一个干净的开始

System check identified no issues (0 silenced). October 13, 2019 - 17:45:05 Django version 2.2.6, using settings 'fpl-django.settings' Starting development server at http://127.0.0.1:8000/ Quit the server with CONTROL-C.

为什么我无法访问网站：localhost:8000？

尝试使用此参数运行 manage.py runserver：0.0.0.0:8000，这将告诉您的应用程序监听来自任何主机的请求。像这样：

{
      "name": "Python: Django",
      "type": "python",
      "request": "launch",
      "program": "${workspaceFolder}/manage.py",
      "console": "integratedTerminal",
      "args": [
        "runserver",
        "0.0.0.0:8000",
        "--noreload",
        "--nothreading"
      ],
      "django": true
}
