ApiGatewayResolver: Avoid having to configure strip_prefixes with pathParameters.proxy

[kbakk]

Hi,

I'm trying to find a way to have the ApiGatewayResolver app be unaware of what the parent resource configured is.

In AWS API Gateway I've configured these resources:

I would like if possible to not have to configure strip_prefixes when creating ApiGatewayResolver. Is that an option?

From the logging I've set up, I see that the message being handled contains a pathParameters.proxy - would there be an option to use that when resolving path?

  ...
  "message": {
    "body": null,
    "httpMethod": "GET",
    "path": "/control/health/ping",
    "pathParameters": {
      "proxy": "health/ping"
    },
    "requestContext": {
      "path": "/control/health/ping",
      "resourcePath": "/control/{proxy+}",
    ...

Many keys omitted

Edit: Related discussion (aws-powertools/powertools-lambda#34) though it doesn't seem like a conclusion on whether to use pathParameters.proxy was made.

hey @kbakk, I'll come back to you later this week on this. Challenge we had was the discrepancy between REST API Gateway, HTTP API Gateway, and ALB -- when Custom Domain and mapping are used, the payload changes and that proxy key wasn't consistent (I need to go back in time to look at payloads again).

The closest to what you're after is using a route prefix: https://awslabs.github.io/aws-lambda-powertools-python/latest/core/event_handler/api_gateway/#route-prefix
