K8S ingress中添加X-Frame-Options SAMEORIGIN

以下是在K8S ingress中添加X-Frame-Options SAMEORIGIN的配置示例：

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: example-ingress
  annotations:
    nginx.ingress.kubernetes.io/configuration-snippet: |
      more_set_headers "X-Frame-Options: SAMEORIGIN";
spec:
  rules:
  - host: www.example.com
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: exampleService
            port:
              number: 80

这个配置示例中，我们在Ingress资源的annotations中添加了nginx.ingress.kubernetes.io/configuration-snippet注释，并使用more_set_headers指令来添加X-Frame-Options: SAMEORIGIN响应标头。
