针对某些响应禁用 nginx 入口控制器中的缓存控制

Question

我有这个入口配置，但所有 html 和 json 响应页面都不包含添加的标头：

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: {{ $app }}-ingress
  labels:
    app: {{ $app }} 
    chart: chart-{{ $app }}
    app.kubernetes.io/managed-by: Helm
  annotations:
    meta.helm.sh/release-name: {{ $app }}
    meta.helm.sh/release-namespace: {{ .Release.Namespace }}
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/proxy-body-size: "{{ $proxy_body_size }}"
    nginx.ingress.kubernetes.io/proxy-read-timeout: "{{ $proxy_read_timeout }}"
    nginx.ingress.kubernetes.io/proxy-connect-timeout: "{{ $proxy_connect_timeout }}"
    nginx.ingress.kubernetes.io/proxy-send-timeout: "{{ $proxy_send_timeout }}"
    nginx.ingress.kubernetes.io/proxy-buffer-size: "{{ $proxy_buffer_size }}"
    nginx.ingress.kubernetes.io/rewrite-target: /$1
    nginx.ingress.kubernetes.io/configuration-snippet : |
        if ($request_uri ~* \.(html|json)) {
           add_header Cache-Control "no-cache,no-store";
        }
spec:
  tls:
    - hosts:
        - {{ $alias }}
  rules:
    - host: {{ $alias }}
      http:
        paths:
          - path: /(.*)
            backend:
              serviceName: {{ $app }}-service
              servicePort: http-back

我只想禁用 html 和 json 内容响应的缓存控制。当我删除 if ($request_uri ~* .(html|json)) 条件时，所有响应都具有添加的标头。所以这意味着配置片段中的条件不正确。

你能帮忙吗？

Answer 1

我遇到了同样的问题，这样的事情对我有用：

      if ($request_uri ~* \.(?:html|json)$) {
        add_header Cache-Control "no-store,no-cache";
        add_header Pragma "no-cache";
      }

Answer 2

这对我有用：

  if ($request_uri ~* \.(?:html|json)$) {
    add_header Cache-Control "no-store, no-cache" always;
    add_header Pragma "no-cache" always;
  }

  if ($request_uri ~*
  \.(?:js|css|png|jpg|jpeg|gif|ico|svg|webp|woff|woff2|ttf)$) {
    add_header Cache-Control "public, max-age=3600" always;
  }
