nginx反向代理导致jupyter 或jupyterlab 无法输出

代码运行能力依赖于websocket，因此需要设置nginx的反向代理

server {
    server_name DOMAIN IP_ADDRESS; # 服务器域名和 IP 地址
    listen 80;
    location / {
        proxy_pass http://127.0.0.1:JUPYTER_PORT/; # JUPYTER_PORT 为 Jupyter 运行端口
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_redirect off;
    }
}
