Managed Service for Apache Flink API 示例代码

本主题包含Managed Service for Apache Flink操作的示例请求块。

要使用 JSON 作为 AWS Command Line Interface (AWS CLI) 操作的输入，请将请求保存在 JSON 文件中。然后，使用 --cli-input-json 参数将文件名传递给该操作。

以下示例说明了如何将 JSON 文件与操作一起使用。


$ aws kinesisanalyticsv2 start-application --cli-input-json file://start.json

有关将 JSON 与一起使用的更多信息 AWS CLI，请参阅AWS Command Line Interface 用户指南中的生成 CLI 框架和 CLI 输入 JSON 参数。
