Feature request: Add support for cookie parameters in OpenAPI schema

[leandrodamascena]

Use case

Original discussion: https://github.com/aws-powertools/powertools-lambda-python/discussions/3609

OpenAPI supports Cookies parameters and we must add support for this!

https://swagger.io/docs/specification/describing-parameters/

Cookie Parameters

Operations can also pass parameters in the Cookie header, as Cookie: name=value. Multiple cookie parameters are sent in the same header, separated by a semicolon and space.

Solution/User Experience

Add Cookie in https://github.com/aws-powertools/powertools-lambda-python/blob/develop/aws_lambda_powertools/event_handler/openapi/params.py

Hi @sthulb, the main challenge here is that you need to identify each payload you have when working with proxies, such as multi-value headers and single-value headers, ALB, APIGateway REST/HTTP, VPC LATTICE v1 and v2, and Lambda function URLs.

For example, when working with ALB, you have this payload for single-value headers:

'headers': {'accept': '*/*', 'cookie': 'power=tools'...

But when working with multi-header values, you have this:

'multiValueHeaders': {'accept': ['*/*'], 'cookie': ['power=tools']..

What I suggest is creating a Lambda and connecting each proxy and variants that work with Lambda and dumping the event, so you can observe how cookies are sent differently in each situation.
