URL 重写

目录

基本概念

ALB 可以在将请求转发到后端之前重写请求 URL。您可以使用正则表达式捕获组来重写 URL。

配置

通过 ingress 注解

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  nginx.ingress.kubernetes.io/rewrite-target: /$2
  name: demo
spec:
  ingressClassName: alb
  rules:
  - http:
      paths:
      - backend:
          service:
            name: frontend
            port:
              number: 8080
        path: /(prefix-x)(/|$)(.*)
        pathType: ImplementationSpecific

通过 rule

apiVersion: crd.alauda.io/v1
kind: Rule
metadata:
  labels:
    alb2.cpaas.io/frontend: alb-00080
    alb2.cpaas.io/name: alb
  name: demo
  namespace: cpaas-system
spec:
  dslx:
  - type: URL
    values:
    - - REGEX
      - ^/(prefix-x)(/|$)(.*)
  rewrite_base: /(prefix-x)(/|$)(.*)
  rewrite_target: /$3

示例：客户端请求 /prefix-x/abc；后端接收到 /abc。
