用于与S3作为AWS服务的AWS Api Gateway集成的SAM模板 [英] SAM Template for AWS Api Gateway Integration with S3 as AWS Service

问题描述

我正在编写SAM模板，我想创建一个API网关，其路径如下:-

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

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

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

这应该能够从S3存储桶下载文件.{airlineName}的值可能类似于 IndiGo.jpg .

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

我能够手动创建它.但是，问题是我找不到适合SAM模板的文档.我需要使用SAM自动化我的API网关.

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.

值如下:-集成类型-AWS服务

AWS Region- eu-west-3

AWS服务-简单存储服务(S3

Http方法-GET

路径覆盖-航空公司/静态/图片/{airlineName}

推荐答案

您必须使用

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.
