无法用vs-代码连接到容器中运行的django进程。

Question

我在连接使用vs代码生成的容器中运行的django进程时遇到了问题。一切似乎都正常，我得到了服务器的启动消息，但是当连接到localhost:8000时，我没有得到响应.

启动容器时，我会收到一条已发布的端口消息：

发布的端口: 8000/tcp -> 127.0.0.1:8000

在启动launch.json调试时，也是一个干净的开始。

系统检查没有发现任何问题(0被沉默)。2019年10月13日-17:45:45:05 Django版本2.2.6，使用设置‘fpl django.set’在http://127.0.0.1:8000/启动开发服务器，退出带有CONTROL的服务器。

为什么我不能访问这个网站: localhost:8000？

devcontainer.json：

    // For format details, see https://aka.ms/vscode-remote/devcontainer.json or the definition README at

尝试使用这个param：0.0.0.0:8000运行manage.py runserver，这将告诉您的应用程序侦听来自任何主机的请求。就像这样：

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