简略记一下，便于自己以后查阅。

安装Nginx

转发路径假设为/ws，配置文件添加

  location /ws
    {
      proxy_pass http://127.0.0.1:1080;
      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 REMOTE-HOST $remote_addr;
      proxy_redirect off;
      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection "upgrade";

      add_header X-Cache $upstream_cache_status;

      add_header Cache-Control no-cache;
    }

其中127.0.0.1:1080是开在本地的一个ws端。
