amazon-web-services - 获取 CDK 文档中定义的 key 的 'extraneous key is not permitted'

Question

我正在尝试从 CDK 在我的 Cloudformation 堆栈中设置 DefaultCacheBehaviorProperty。按照此处的官方文档:link

代码如下:

const defaultCacheBehaviour: CfnDistribution.DefaultCacheBehaviorProperty = {
            compress: true,
            viewerProtocolPolicy: "redirect-to-https",
            targetOriginId: "api-gw-origin",
            forwardedValues: {
                queryString: true
            },
            lambdaFunctionAssociations: [
                {
                    eventType: LambdaEdgeEventType.VIEWER_REQUEST,
                    lambdaFunctionArn: this.getLambdaEdgeArnString(CHECK_AUTH_LAMBDA_EDGE_ARN_PARAM_NAME)
                }
            ],
            defaultTtl: 0,
            minTtl: 0,
            maxTtl: 0
        }

cloudfrontDistribution.distribution.addPropertyOverride("DistributionConfig.DefaultCacheBehavior",
            defaultCacheBehaviour
        );

现在在 Cloudformation 中部署时，我收到错误:

Properties validation failed for resource CloudfrontDistributionECD with message:
#/DistributionConfig/DefaultCacheBehavior: extraneous key [minTtl] is not permitted
#/DistributionConfig/DefaultCacheBehavior: extraneous key [compress] is not permitted
#/DistributionConfig/DefaultCacheBehavior: extraneous key [maxTtl] is not permitted
#/DistributionConfig/DefaultCacheBehavior: extraneous key [viewerProtocolPolicy] is not permitted
#/DistributionConfig/DefaultCacheBehavior: extraneous key [forwardedValues] is not permitted
#/DistributionConfig/DefaultCacheBehavior: extraneous key [lambdaFunctionAssociations] is not permitted
#/DistributionConfig/DefaultCacheBehavior: extraneous key [defaultTtl] is not permitted
#/DistributionConfig/DefaultCacheBehavior: extraneous key [targetOriginId] is not permitted

似乎文档已经过时了？有什么解决办法吗？

Answer 1

您尝试设置的许多字段已被弃用。如果您查看链接的文档中的字段描述，它就写在那里。

补充:你为什么选择 L1 结构？您可以更轻松地使用 L2 构造 Distribution创建您的 CloudFront 分配并在其中设置默认行为属性。

除此之外，也按照文档中的建议，您应该使用cachePolicy 来定义缓存行为，例如最小、最大、默认 ttl
