我正在编写一个Cloudformation配置文件以一次性创建一个网站。这包括创建lambda函数，创建API网关，设置S3存储桶，创建Route 53区域和记录。
至今：
- 创建Lambda函数及其角色（有效）
- 创建API网关，它的部署及其角色（有效）
- 创建一个S3存储桶及其策略（有效）
- 创建站点的Route 53区域和DNS记录（有效）
- 为API网关创建一个域（不知道我在做什么）
因此，domain.com可以毫无问题地提供S3存储桶中的文件。将AWS URI用于API网关可以正常工作https://trydsoonjc.execute-api.us-west-2.amazonaws.com/app/path/here。
我要设置的是api.domain.com指向API网关以访问服务器的API。
如何将Route 53连接到API Gateway？
我现在的Cloudformation是这样的：

自定义域名（主机名）没有直接指向API网关端点。它指向基础的CloudFront分发，该分发是在 API Gateway配置为期望/支持自定义域名之后由API Gateway创建/拥有/控制的。这比简单地在Route 53中创建记录要复杂得多。除非您已经熟悉此过程，否则您将需要复审使用自定义域名作为API网关API主机名。

作为配置的一部分，您还需要为自定义主机名提供SSL证书，或从Amazon Certificate Manager获取一个证书，因为API Gateway要求启用HTTPS。
