使用SAM创建API网关代理资源

问题描述

我在SAM（亚马逊的无服务器应用程序模型）中创建代理资源的要求很简单。实际上如此简单，以至于亚马逊的文档似乎将其保留为

I have an apparently-simple requirement to create a proxy resource in SAM (Amazon's Serverless Application Model). So simple in fact that Amazon's documentation appears to leave this as an exercise to the reader!
I want to create an AWS API Gateway catch-all endpoint to proxy everything to another HTTP service.
In the AWS Console, the configuration I am trying to build looks as follows:
I have seen this excellent post by Christian Johansen and his related Stack Overflow question here for how to do the same thing in CloudFormation. I suppose I could just use that code in SAM, however, SAM has its implicit and explicit APIs, so I want to avoid creating explicit resources if the "right way" is to refer to implicit resources.
Does anyone know how to do this?
 解决方案 
After a lot of playing around, I believe I found the answer in an example here. The diff relative to the Hello World example that SAM sets up for you out of the box is:
diff --git a/sam-app/template.yaml b/sam-app/template.yaml
index 02cd901..f349dcc 100644
--- a/sam-app/template.yaml
+++ b/sam-app/template.yaml
