4.2. 第 2 步 - 为您的 API 设置 HTTPRoute

流程

1. 输入以下命令为您的 Toystore 应用程序 API 定义 HTTP 路由：

   kubectl apply -f - <<EOF
   apiVersion: gateway.networking.k8s.io/v1
   kind: HTTPRoute
   metadata:
     name: toystore
     labels:
       deployment: toystore
       service: toystore
   spec:
     parentRefs:
     - name: ${gatewayName}
       namespace: ${gatewayNS}
     hostnames:
     - "api.${rootDomain}"
     rules:
     - matches:
       - method: GET
         path:
           type: PathPrefix
           value: "/cars"
       - method: GET
         path:
           type: PathPrefix
           value: "/dolls"
       backendRefs:
       - name: toystore
         port: 80
     - matches:
       - path:
           type: PathPrefix
           value: "/admin"
       backendRefs:
       - name: toystore
         port: 80
   EOF

   使用这个 HTTPRoute 时，部署的服务现在由网关公开。

2. 您可以通过 HTTPS 访问 API 端点，如下所示：

   export INGRESS_HOST=$(kubectl get gtw ${gatewayName} -o jsonpath='{.status.addresses[0].value}' -n api-gateway)
   
   curl --resolve api.${rootDomain}:443:${INGRESS_HOST} "https://api.${rootDomain}/cars"
