我们有一个可以通过http和https协议访问的服务。由于我们有一些基于http和https协议的授权模块，我们需要将http请求重定向到端口号80和基于https的请求分别重定向到443端口号。
例如：
是否也可以允许收听多个端口（例如443和80），然后将传入的请求转发到https://demo.example.com到service1，将http://demo.example.com转发到service2？
我们已将Nginx Ingress控制器配置如下：
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: lenspiingress
namespace: nginx-ingress
annotations:
kubernetes.io/ingress.class: "nginx"
ingress.kubernetes.io/affinity: "cookie"
ingress.kubernetes.io/session-cookie-name: "route"
ingress.kubernetes.io/session-cookie-hash: "sha1"
ingress.kubernetes.io/ssl-redirect: "false"
spec:
tls:
- hosts:
- demo.example.com
secretName: tls-secret
rules:
- host: demo.example.com
http:
paths:
- path: /
backend:
serviceName: apidemo
servicePort: 80
我们的服务就像，
apiVersion: v1
kind: Service
metadata:
labels:
run: demodeployment
name: apidemo
namespace: nginx-ingress
spec:
ports:
- name: port-1
nodePort: 31120
port: 80
protocol: TCP
targetPort: 80
- name: port-2
nodePort: 30850
port: 443
protocol: TCP
targetPort: 443
selector:
run: demodeployment
type: NodePort
使用Nginx入口控制器时，我们可以重定向到80或443端口中的任何一个。
是否可以设置入口将http请求重定向到端口80，将基于https的请求重定向到端口443？我们的意思是我们可以在“Ingress”中设置监听端口并根据端口重定向。< / p>
