如何強制 Nginx Ingress 控制器回應 HTTP 426 已棄用的路由

Question

我在 Kubernetes 上的命名空間有以下入口和路徑/api/1.0/重定向到我的舊服務，其餘的重定向到新服務。在棄用和刪除我的舊服務之前，我希望 Nginx 僅在以下位置回應 HTTP 426 重定向錯誤代碼：/api/1.0/路徑。

我怎樣才能做到這一點 ？

apiVersion: networking.k8s.io/v1
kind: Ingress

  name: xxx-ingress
  namespace: xxx-ingress

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

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