AWS recently released Cloudformation support for templating websocket API gateways https://aws.amazon.com/about-aws/whats-new/2019/02/automate-websocket-api-creation-in-api-gateway-with-cloudformation/. I have a working example deployed, but I can't work out how to turn on the proxy integration response (see screenshot for how this is done in the console). Does anyone know what cloudFormation setting can be used to turn on a default integration response for lambda proxy integrations?
请尝试以下步骤
1- 在 Route 中添加 RouteResponseSelectionExpression 作为 $default（目前仅支持一种）
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）
以下是经过测试的 CFN 片段，请随意使用
