当我在websocket-server

Question

Nginx配置

upstream websocketserver {
    server localhost:8080;
}

server {
    server_name wss.website.test;

    listen 443 ssl;
    ssl_certificate /etc/nginx/ssl/nginx.crt;
    ssl_certificate_key /etc/nginx/ssl/nginx.key;

    access_log  /app/vagrant/nginx/log/wss-access.log;
    error_log   /app/vagrant/nginx/log/wss-error.log;
    location / {
        proxy_pass http://websocketserver;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;

        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto https;
        proxy_read_timeout 86400; # neccessary to avoid websocket 
        proxy_redirect off;
   }
}

有一个WS-server在端口8080上运行（它不使用任何TLS证书等）并基于Ratchet（http://socketo.me/）。

所以问题是真正的WSS或者这只是通常的而不是安全的WS与nginx语法糖的某些部分？
