我有应用程序“test.abc.com“。我想在不同的服务之间传输请求。

示例或预期输出

• 当用户点击test.abc.com--〉时，它将转到abc-demo-frontend-external服务
• 当用户点击test.abc.com/main.js或test.abc.com/main.css或任何.css/ .js文件--〉时，将转到abc-demo-frontend服务

我添加了以下配置

apiVersion: networking.k8s.io/v1
        kind: Ingress
        metadata:
          name: test-demo-frontend-ingress
          annotations:
            kubernetes.io/ingress.class: nginx
            nginx.ingress.kubernetes.io/ssl-redirect: 'false'
            nginx.ingress.kubernetes.io/use-regex: "true"
        spec:
          rules:
            - host: "test.abc.com"
              http:
                paths:
                  - path: /[^\/#?]+\.(?:css|js)(?![^\/?#])
                    pathType: ImplementationSpecific
                    backend:
                      service:
                        name: abc-demo-frontend
                        port:
                          number: 80
                  - path: /
                    pathType: ImplementationSpecific
                    backend:
                      service:
                        name: abc-demo-frontend-external
                        port:
                          number: 80

添加[^\/#?]+\.(?:css|js)(?![^\/?#])路径后，我得到503，为什么？
当我添加下面路径时，我得到503，为什么？

- path: /[^\/#?]+\.(?:css|js)(?![^\/?#])
                        pathType: ImplementationSpecific
                        backend:
                          service:
                            name: abc-demo-frontend
                            port:
                              number: 80
