Using Cloudfront with an HTTP API Origin

Question

I want to redirect HTTP traffic to HTTPS. So I want to put my app, which runs on an API Gateway, behind Cloudfront. But I want to use aws_cdk.aws_cloudfront to launch my Cloudfront instance.

self.distribution = cloudfront.Distribution(
    self,
    construct_id,
    default_behaviour=cloudfront.BehaviorOptions(
        origin=cloudfront_origins.RestApiOrigin(api),
        ...

This would be my ideal implementation. But my api is of type HttpApi; I am using aws_apigatewayv2_alpha.

Is there any way I can use an HttpApi as the origin of my Cloudfront distribution, using aws_cloudfront?

You can create Origins from any HTTP endpoint like below, given the domain name, and optionally, other origin properties.

# Creates a distribution from an HTTP endpoint
cloudfront.Distribution(self, "myDist",
    default_behavior=cloudfront.BehaviorOptions(origin=origins.HttpOrigin("www.example.com"))
)

Thanks. Yes I'm currently following that method, but I don't want to hardcode my URL. I'm creating the API using the cdk, so I have an api_stack.py that runs apigw.HttpApi(...), and I'm then taking that instance's property url and trying to pass it into HttpOrigin. The problem is that the url value looks like this ${Token[TOKEN.622]}.execute-api.eu-west-2.${Token[AWS.URLSuffix.8]}/ (https:// prefix manually removed).

I presume these Tokens are a way of waiting for AWS to resolve values, though they're new to me.

It also seems it would be very possible using the console, though I want to keep it all in code.

Here's an example of a dynamically passed url (though they're using RestApi). I presume they don't have Token issues.

Sorry, I couldn't understand your concerns can you please explain a bit more clearly?
