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。
