Questions about CORS on HTTP (Api Gateway V2) APIs: HTTP_PROXY integrations

Hi There

Looking at your documentation provided, it says:

When you enable CORS and authorization for the $default route, there are some special considerations. The $default route catches requests for all methods and routes that you haven't explicitly defined, including OPTIONS requests. Now, the CLI example provided is the basic for enabling CORS on the $default route, which takes care of all the other routes.

Looking at the documentation for the APIv2 CLI, you can use the --route-selection-expression parameter.

The route selection expression for the API. For HTTP APIs, the routeSelectionExpression must be ${request.method} ${request.path}. If not provided, this will be the default for HTTP APIs. This property is required for WebSocket APIs.

So if you would like to add CORS to a specific route, your CLI would look something like this:

aws apigatewayv2 update-api --api-id api-id --route-selection-expression ${request.method} ${request.path} --cors-configuration AllowOrigins="https://www.example.com"

Hope that helps.
