SAM Template for AWS Api Gateway Integration with S3 as AWS Service

问题

I am writing SAM templates and I want to create an API Gateway with the path as follows:-

http:///userFlights/airlines/static/images/{airlineName}.

This should be able to download the file from S3 bucket. The {airlineName} may have value like IndiGo.jpg.

I am able to create this manually. Nevertheless, the problem is I am not able to find the appropriate Documentation for SAM templates. I need to automate my API Gateway with SAM.

The values are as follows:- Integration type - AWS Service

AWS Region- eu-west-3

AWS Service - Simple Storage Service (S3

Http Method - GET

Path override- airlines/static/images/{airlineName}

You have to make use of an OpenAPI definition using DefinitionBody in your SAM template that defines the API configuration. Check out the S3 proxy example here. I have built an API with the simplest and minimum Swagger definition and deployed via SAM.
