如何强制 Nginx Ingress 控制器对已弃用的路由响应 HTTP 426

Question

我在 Kubernetes 上的命名空间有以下入口，路径如下/api/1.0/重定向到我的旧服务，其余重定向到新服务。在弃用和删除我的旧服务之前，我希望 Nginx 仅在以下情况下响应 HTTP 426 重定向错误代码：/api/1.0/路径。

我怎样才能做到这一点 ？

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: xxx-ingress
  namespace: xxx-ingress

    nginx.ingress.kubernetes.io/proxy-body-size: "0"

    nginx.ingress.kubernetes.io/proxy-pass-headers: "Content-Length"
