support for stage variables in lambda and https integration

❓ General Issue

How to pass a stage variable to lambda function field in API Gateway?

I have an API Gateway that triggers a lambda function specified by a stage variable stageVariables.lbfunc.

How can I create this API Gateway with AWS CDK?

It looks like that I should create a special handler for LambdaRestApi.

But I can’t find any example code for doing this.

The following is my current code. I wish that LambdaIntegration’s handler can be determined by a stage variable.

# dev_lambda_function should be replaced by something else
dev_lambda_function = lambda_.Function(self, "MyServiceHandler",
            runtime=lambda_.Runtime.PYTHON_3_7,
            code=lambda_.Code.asset("resources"),
            handler="lambda_function.lambda_handler",
            description="My dev lambda function"
            )
stage_options = apigateway.StageOptions(stage_name="dev", 
    description="dev environment", 
    variables=dict(lbfunc="my-func-dev")
)
# What should I pass to the handler variable so that LambdaRestApi triggers the lambda function specified by the stage variable "stageVariables.lbfunc"?
api = apigateway.LambdaRestApi(self, "my-api",
            rest_api_name="My Service",
            description="My Service API Gateway",
            handler=dev_lambda_function,    
            deploy_options=stage_options)

Environment

• CDK CLI Version: 1.22.0 (build 309ac1b)

Any update on this issue? We are currently blocked with this and would like to know if there are any alternative approach?

Agree with rampatina - the inability to pass stage variables negates the ability to utilize API-GW stages as they were designed/intended to be used, forcing sub-optimal design of multiple GWs; one per stage.
