我的 RequestAuthentication 是这个

apiVersion: security.istio.io/v1beta1
kind: RequestAuthentication
metadata:
  name: testing-dev-authenticator
  namespace: istio-system
spec:
  selector:
    matchLabels:
      istio: ingressgateway
  jwtRules:
  - issuer: "https://www.googleapis.com/service_accounts/v1/jwk/securetoken@system.gserviceaccount.com"
    jwksUri: "https://securetoken.google.com/<project-name>"

我的 AuthorizationPolicy 是这个

apiVersion: security.istio.io/v1beta1
kind: AuthorizationPolicy
metadata:
 name: test-dev-authorizer-all-svc
 namespace: dev
spec:
 action: ALLOW
 rules:
 - from:
   - source:
       notRequestPrincipals: ["*"]
   to:
   - operation:
       notPaths: ["/message/ping"]

我的要求是我不希望 jwt auth 检查 healthz（我的情况是 /message/ping），但我总是得到 上面的响应是“RBAC：访问被拒绝”

我希望对部署在“dev”命名空间中的所有 pod 进行身份验证，除了运行状况检查，它的路径是 path : ["/user/ping", "/message/ping"] 但我无法同时提供两者

我已经复制了您的问题，并且我认为它正在按照您希望的方式工作。

有我的 RequestAuthentication 和 AuthorizationPolicy yamls。

apiVersion: security.istio.io/v1beta1
kind: RequestAuthentication
metadata:
  name: testing-dev-authenticator
  namespace: istio-system
spec:
  selector:
    matchLabels:
      istio: ingressgateway
  jwtRules:
  - issuer: "testing@secure.istio.io"
    jwksUri: "https://raw.githubusercontent.com/istio/istio/release-1.8/security/tools/jwt/samples/jwks.json"

apiVersion: security.istio.io/v1beta1
kind: AuthorizationPolicy
metadata:
  name: require-jwt
  namespace: istio-system
spec:
  selector:
    matchLabels:
      istio: ingressgateway
  action: ALLOW
  rules:
  - from:
    - source:
        requestPrincipals: ["*"]
    to:
    - operation:
        paths: ["/productpage"]
  - to:
    - operation:
        paths: ["/api/v1/products"]

您可以使用以下内容从 JWT 中排除路径（例如“/api/v1/products”），当“/productpage”需要 JWT 时，将拒绝所有没有令牌的请求。

如果您想排除多个路径，那么这应该有效：

paths: ["/api/v1/products","/login"]

所以在你的情况下

paths: ["/user/ping", "/message/ping"]

我已经在bookinfo应用程序上测试了上述配置。

有我用过的token

TOKEN=$(curl https://raw.githubusercontent.com/istio/istio/release-1.8/security/tools/jwt/samples/demo.jwt -s)

测试：

api/v1/products
Without token
200
With token
200
------------------------------------------------------------------
/productpage
Without token
403
With token
200

您还提到您想在特定的命名空间中执行此操作，然后您可以尝试使用这些 RequestAuthentication 和 AuthorizationPolicy yamls。

apiVersion: security.istio.io/v1beta1
kind: RequestAuthentication
metadata:
  name: testing-dev-authenticator
  namespace: dev
spec:
  jwtRules:
  - issuer: "testing@secure.istio.io"
    jwksUri: "https://raw.githubusercontent.com/istio/istio/release-1.8/security/tools/jwt/samples/jwks.json"

apiVersion: security.istio.io/v1beta1
kind: AuthorizationPolicy
metadata:
 name: test-dev-only-authorized-api
 namespace: dev
spec:
 action: DENY
 rules:
 - from:
   - source:
        notRequestPrincipals: ["*"]
   to:
   - operation:
       paths: ["/productpage"]

同样基于bookinfo应用程序。

测试：

api/v1/products
Without token
200
With token
200
------------------------------------------------------------------
/productpage
Without token
403
With token
200
