你好，我有django应用程序让我们假设我的网站uri是example.com现在我想路由我的管理 Jmeter 板到另一个端口，就像如果用户类型abc.example.com它自动路由到我的应用程序的主页，但我想有abc.example.com:445/admin/*是可能的解决方案，我尝试了

server {
  listen 443 ssl;
  server_name abc.example.com;
  client_max_body_size 500M;

  ssl_certificate /etc/nginx/my.crt;
  ssl_certificate_key /etc/nginx/server.key;

  location / {
    proxy_set_header   X-Forwarded-For $remote_addr;
    proxy_set_header   Host $http_host;
    proxy_set_header   Upgrade $http_upgrade;
    proxy_set_header   Connection "upgrade";
    proxy_pass http://localhost:3001;
  }
} 
server{
  listen 445 ssl;
  server_name abc.example.com;
  client_max_body_size 500M;

  ssl_certificate /etc/nginx/my.crt;
  ssl_certificate_key /etc/nginx/server.key;

  location /admin {
    proxy_set_header   X-Forwarded-For $remote_addr;
    proxy_set_header   Host $http_host;
    proxy_set_header   Upgrade $http_upgrade;
    proxy_set_header   Connection "upgrade";
    proxy_pass http://localhost:3001;
  }
}

server {
  listen 80;
  server_name abc.example.com;
  return 301 https://$host$request_uri;
}

但这本身路由到端口443和/管理页面也有，所以如何避免这种任何可能的解决方案.
