Nginx 反向代理 wss

加上 map 和 相关内容就可以了。如：

map $http_upgrade $connection_upgrade {
 default upgrade;
 '' close;
}

server {
    listen 80;
    server_name ssh.caoaman.cn;

    location / {
      proxy_redirect off;
      proxy_set_header Host $host;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_read_timeout 3600s;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection $connection_upgrade;
      proxy_pass http://home.caoaman.cn:5032/;
    }
}
