如何设置 websocket 服务器以及两个 laravel 后端和一个 spa

Question

我在不同的路由上设置了两个 laravel 后端。并且根目录上有一个 spa。现在我想设置一个 websocket 服务器。这是我的 website.conf

    location ~ /\.(?!well-known).* {

该location /ws块取自 laravel websockets 文档。但此位置块给出 404 未找到错误。但这个 nginx 配置不起作用。我的 laravel 网站项目在 localhost 上运行良好。

这是输出lsof -i :80,443,6001
