我使用 CloudFormation
设置了 APIGateway
,它将一个方法暴露为 /customers/{customerId}
. 该方法调用 dynamodb
service而不是使用任何lambda,如果缺少映射,则返回带有空对象的 HTTP 200
或带有 HTTP 200
的 customer
对象 .
现在,我想为我的 prod
阶段设置缓存 . 我有一个现有的api,我使用AWS APIGateway Web UI创建并创建了prod阶段 . 我想在CF中复制这些属性 . 这就是我在旧api中所拥有的
Cache Settings
缓存状态:可用
缓存容量:0.5GB
缓存生存时间(TTL):300
Per-key cache invalidation
需要授权:checked处理未经授权的请求:忽略缓存控制头;在响应标头中添加警告
Default Method Throttling
启用限制:已选中
费率:1000
爆裂:200
我尝试设置这样的第一部分(缓存设置),但它没有像我期望的那样产生所需的prod阶段设置 . 如何使用CloudFormation实现所需的上述输出?

在每个阶段的属性中你需要设置
"CacheClusterEnabled": true
,即:以下是文档:API Gateway Stage(CacheClusterEnabled):http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-apigateway-stage.html#cfn-apigateway-stage-cacheclusterenabled
API网关方法设置(注意,首先必须在舞台上启用缓存):http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-apigateway-stage-methodsetting.html#cfn-apigateway-stage-methodsetting-cachingenabled
