我想在我的主机ubuntu虚拟机上配置nginx作为反向代理，指向运行在docker端口8888上的jupyterhub。我使用子路径，而不是子域，我的公司防火墙只允许我访问端口80和443，所有其他端口都被阻止，这就是为什么我不能使用rewrite。这可以工作，但不显示来自jupyter hub的资源（css文件、图像等）页面路径myservername.com/jphubdisplays，但资源从myservername.com加载（没有子路径/jphub）Ex（徽标从www.example.com加载myservername.com/hub/logo而不是myservername.com/jphub/hub/logo。
有人知道我这样做是否正确吗？我应该在配置中更改什么？

upstream jupyter {
        server localhost:8888;
        keepalive 32;
}
server {
  listen 80;
  server_name myservername.com;
  ssl_certificate  /etc/ssl/cert-request/cert.pem;
  ssl_certificate_key /etc/ssl/private/cert.key; 
  ssl_prefer_server_ciphers on;

location /jphub/ {
    proxy_pass http://jupyter/;
    proxy_http_version 1.1;
proxy_redirect default;
proxy_redirect / /jphub/;
proxy_redirect  http://jupyter/ https://$host/jphub/;
