我正在尝试使用频道建立一个 django 实例。我已经成功部署在一个开发环境中，我可以使用 django runserver 将数据服务到本地主机。在我的 prod 环境中，我使用 apache 作为启用了 mod_proxy_wstunnel 的 proxypass 服务器。服务器启动正常，但是当我在浏览器中打开时，在 runserver 控制台中出现以下错误：

我相关的 apache 配置是这样的：

RewriteEngine On
DocumentRoot /var/www/html/django-ui
ProxyPass /static/ !
Alias /static/ /var/www/html/django-ui/cyberSA/static/
  <Location "/">
    ProxyPass "ws://localhost:8000/"
  </Location>

我试图在 http_protocol 文件中隔离问题，它似乎与协议对象有关。我在这里想念什么？
