45.3. 使用方法
本节论述了如何使用 protobuf-deserialize-action
。
45.3.1. Knative 操作
您可以使用 protobuf-deserialize-action
Kamelet 作为 Knative 绑定中的中间步骤。
protobuf-deserialize-action-binding.yaml
apiVersion: camel.apache.org/v1alpha1 kind: KameletBinding metadata: name: protobuf-deserialize-action-binding spec: source: ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: timer-source properties: message: '{"first": "John", "last":"Doe"}' steps: - ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: json-deserialize-action - ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: protobuf-serialize-action properties: schema: "message Person { required string first = 1; required string last = 2; }" - ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: protobuf-deserialize-action properties: schema: "message Person { required string first = 1; required string last = 2; }" sink: ref: kind: Channel apiVersion: messaging.knative.dev/v1 name: mychannel
45.3.1.1. 前提条件
请确定您已将 "Red Hat Integration - Camel K" 安装到您连接的 OpenShift 集群中。
45.3.1.2. 使用集群 CLI 的步骤
-
将
protobuf-deserialize-action-binding.yaml
文件保存到您的本地驱动器中,然后根据需要编辑它。 使用以下命令运行操作:
oc apply -f protobuf-deserialize-action-binding.yaml
45.3.1.3. 使用 Kamel CLI 的步骤
使用以下命令配置并运行操作:
kamel bind --name protobuf-deserialize-action-binding timer-source?message='{"first":"John","last":"Doe"}' --step json-deserialize-action --step protobuf-serialize-action -p step-1.schema='message Person { required string first = 1; required string last = 2; }' --step protobuf-deserialize-action -p step-2.schema='message Person { required string first = 1; required string last = 2; }' channel:mychannel
这个命令会在集群的当前命名空间中创建 KameletBinding。
