操作

以下代码示例演示如何使用 batch-put-message

Amazon CLI

向 Amazon IoT Events 发送消息(输入)

以下batch-put-message示例向 Amazon IoT Events 系统发送了一组消息。每个消息有效载荷都将转换为您指定的输入 (inputName),并输入到任何监视该输入的检测器中。如果发送了多条消息,则无法保证消息的处理顺序。为了保证顺序,您必须逐一发送一条消息,然后等待成功响应。

aws iotevents-data batch-put-message \ --cli-binary-format raw-in-base64-out \ --cli-input-json file://highPressureMessage.json

highPressureMessage.json 的内容:

{ "messages": [ { "messageId": "00001", "inputName": "PressureInput", "payload": "{\"motorid\": \"Fulton-A32\", \"sensorData\": {\"pressure\": 80, \"temperature\": 39} }" } ] }

输出:

{ "BatchPutMessageErrorEntries": [] }
