API v4 basePath configuration

[lutangar]

The API prefix is currenlty configured via route prefix in config/routes/api_platform.yaml:

api_platform:
    resource: .
    type: api_platform
    prefix: /v4

The problem is when dumping the OpenAPI definition :

docker-compose exec php bin/console api:openapi:export --yaml --output=oas.yaml

The server baseUrl is still set to /:

servers:
  -
    url: /
    description: ''
paths:
  '/v4/contributors/{id}':

We can manually set the baseUrl in a custom OpenApiFactory:

$context[ApiPlatformOpenApiFactory::BASE_URL] = '/v4/';

But this doesn't get rid of the prefix on the paths...

Ideally there should be a way to configure a baseUrl in ApiPlatform configuration and this baseUrl would then be used in the OpenAPI generation.

This would result in the following:

servers:
  -
    url: /v4/
    description: ''
paths:
  '/contributors/{id}':

Maybe if there was a way to override the api_platform.router we could set the router.request_context.base_url to v4 there.
