how to forward request_uri from ingress to backend pods via service

Question

I am sharing my ingress file and also working nginx conf file

not working ingress for path based routing

apiVersion: networking.k8s.io/v1

kind: Ingress

metadata:

  name: originqa-ingress

  namespace: logging

  annotations:

    nginx.ingress.kubernetes.io/rewrite-target: /$1

    nginx.ingress.kubernetes.io/use-regex: "true"

spec:

  ingressClassName: nginx

  rules:

  - host: originqa-test.example.com

    http:

      paths:

      - backend:

          service:

            name: svc-originqa

            port:

              number: 5000

        path: /

        pathType: Prefix

      - backend:

           service:

             name: svc-originqa-sitemap

             port:

               number: 80

        path: /(.+\.(?:xml))$

        pathType: Prefix

and given below nginx.conf is producing correct result which I have translated to above ingress. but if any request coming to / then it is working. but I have created a regex "/(.+.(?:xml))$" which basically is, if anything ends with .xml just after / like "/sitemap_index.xml" then it is not working. it is happening because ingress is not forwarding $requst_uri to backend pods via svc-originqa-sitemap service.

So can anyone please help me with this?

Problem:- nginx-ingress is not forwarding $request_uri to backend pods via svc-originqa-sitemap service.

desired solution:- svc-originqa-sitemap:80$request_uri

################# working nginx conf ###############################

server {

    listen       80;

    server_name  sitemaptest.example.com;



   

    error_log  /var/log/nginx/sitemap.error.log;

    access_log  /var/log/nginx/sitemap.access.log;



    location ~ /(.+\.(?:xml))$ {

        proxy_pass http://10.0.1.44:202$request_uri;

}

}
