尝试将nginx中的一个页面重定向到http，将所有其他页面重定向到https

Question

我在Ubuntu 16和nginx中使用CakePHP 2.9，我有一个安装了ssl证书的vps，我想使用带有php棘轮的javascript websockets。问题是它们无法开箱即用。例如，在不改变firefox中的某个设置about：config的情况下，我不能在浏览器中使用ws websockets（如果我希望其他人能够使用它，那就不好了）。但我也无法让PHP Ratchet接受wss websockets。所以，我正在尝试将websockets将要运行的页面重定向到http，所以我可以使用常规的ws并连接到PHP棘轮。

问题是，我似乎无法让我的nginx配置文件顺利完成。我将它重定向到我想要使用websockets的页面上，但它似乎给出了404错误。这可能是我的网站DNS的问题，但这里是我正在使用的nginx配置：

server {
    listen 80;
    listen [::]:80;

    server_name server.com;

    location /websocket_path {
    }

    location / {
        return 301 https://$server_name/web/$request_uri/;
    }
}

    listen 443 ssl http2 default_server;
    listen [::]:443 ssl http2 default_server ipv6only=on;

    location / {

对此事的任何帮助将不胜感激。谢谢。
