amazon-web-services - 使用 CloudFormation 添加对 AWS websocket API 的集成响应

Question

AWS recently released Cloudformation support for templating websocket API gateways 。我部署了一个工作示例，但我无法弄清楚如何打开代理集成响应(有关如何在控制台中完成此操作的屏幕截图)。有谁知道什么 cloudFormation 设置可用于打开 lambda 代理集成的默认集成响应？

Answer 1

请尝试以下步骤

1- 在 Route 中添加 RouteResponseSelectionExpression 作为 $default(目前仅支持一个)

2-为所有路由创建RouteResponse(双向)注意:- RouteResponseKey: $default//只能是默认值

3-添加ConnectIntegResponse(可选)

下面是经过测试的 CFN 片段，请随意使用
