使用SAM创建API网关代理资源 [英] Create an API Gateway Proxy Resource using SAM

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

我见过Christian Johansen撰写的这篇出色的帖子及其相关的Stack Overflow问题，了解如何在CloudFormation中执行相同的操作。我想我可以在SAM中使用该代码，但是SAM具有其隐式和显式的API，因此如果正确的方法是指隐式资源，则我想避免创建显式资源。

有人知道怎么做吗？

解决方案

经过很多次尝试，我相信我在示例中找到了答案此处。相对于SAM开箱即用的Hello World示例的差异是：

  diff --git a / sam-app / template.yaml b / sam-app / template.yaml 
索引02cd901..f349dcc 100644

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?

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

--- a/sam-app/template.yaml
+++ b/sam-app/template.yaml
