aws-api-gateway - 使用 CloudFormation 为 APIGateway 设置阶段环境(缓存)

Question

我已经设置APIGateway使用CloudFormation其中公开了一种方法 /customers/{customerId} 。该方法调用dynamodb服务而不是使用任何 lambda 并发回 HTTP 200如果映射丢失或 customer 则为空对象对象 HTTP 200 。

现在，我想为我的 prod 设置缓存阶段。我有一个使用 AWS APIGateway Web UI 创建的现有 api 并创建了生产阶段。我想在 CF 中复制这些属性。这是我的旧 api 中的内容

缓存设置

缓存状态:可用

缓存容量:0.5GB

缓存生存时间 (TTL):300

每键缓存失效

需要授权:已选中处理未经授权的请求:忽略缓存控制头；在响应 header 中添加警告

默认方法限制

启用节流:选中

价格:1000

爆发:200

我尝试像这样设置第一部分(缓存设置)，但它没有像我预期的那样产生所需的产品阶段设置。我如何使用 CloudFormation 获得所需的上述输出？

在每个阶段的属性中需要设置"CacheClusterEnabled": true，即:

"TestStage" : {
        "Type" : "AWS::ApiGateway::Stage",
        "Condition":"CreateTestStage",
        "Properties" : {
            "DeploymentId" : {"Ref":"ApiDeployment"},
            "Description" : "Test Stage",
            "RestApiId" : {"Ref":"MyAPI"},
            "StageName" : "test",
            "CacheClusterEnabled": "true"
        }
    },
