首先需要准备一个Lambda function(Lambda->Functions)

还要准备一个证书，要覆盖子域名（AWS Certificate Manager->Certificates）。

1、API Gateway->Create API->REST API->Build->API endpoint type( Edge-optimized )->Create API

2、Resources->Create method->Method type(GET)->Integration type(Lambda function)->

Create method

3、Resources->/->GET(/ - GET - Method execution)->Test->结果正确否

4、Resources->Deploy API->Stage(*New Stage*)->Stage name(prod)

5、Stages->prod->/->GET->Invoke URL(https://xxxxxxxx.execute-api.us-east-1.amazonaws.com/prod/)，复制地址能访问否

至此，API Gateway已创建完毕

6、CloudFront->Distributions->Create distribution->Origin domain(你的API Gateway)->Origin path - optional(/prod)->Viewer protocol policy(HTTPS only)->Web Application Firewall (WAF)(Do not enable security protections)->Price class(Use only North America and Europe)->Alternate domain name (CNAME) - optional->Add item(abc.yourdomain.com)->Custom SSL certificate - optional->Create distribution

7、CloudFront->Distributions->Domain name(xxxxxx.cloudfront.net)->复制备用

8、Route 53->Hosted zones->yourdomain.com->Create record->Record name(abc)->Record type(CNAME)->Value(复制备用的xxxxxx.cloudfront.net)->Create records

9、访问abc.yourdomain.com

10、nslookup abc.yourdomain.com
