Applying AuthenticationFunc for subrouter

[katyatrue]

Hi.

I'm using your great library in combination with https://github.com/deepmap/oapi-codegen in order to migrate custom endpoints to openApi one by one.
To reach this I defined openApi endpoints in yml file and used dedicated subrouter.
The problem was that authentication was not properly applied for endpoints defined on subrouter (while on the main router it was working fine).

So for the options:

import (
   chi_middleware "github.com/deepmap/oapi-codegen/pkg/chi-middleware"
)
opts := chi_middleware.Options{
		Options: openapi3filter.Options{
			AuthenticationFunc: func(ctx context.Context, input *openapi3filter.AuthenticationInput) error {
				return openapifilterAuthenticationFunc(ctx, input)
			},
		},
	}

used like that:

 v2r := mux.NewRouter().PathPrefix("/api/test").Subrouter()
 v2r.Use(chi_middleware.OapiRequestValidatorWithOptions(doc, &opts))

my authentication test doesn't pass

while if I am defining options for the whole router:
mux.NewRouter().Use(chi_middleware.OapiRequestValidatorWithOptions(doc, &opts))
then authentication tests are passed

I want to authenticate with AuthenticationFunc on subrouter as it provides much more flexibility on migration scenarios

Is there a way to fix it?

Were you able to find some help over at chi_middleware ?

Hey both - I think this question was largely around "can we tweak the openapi3filter.Filter to only match against a subpath within the router, or does it have to be applied to the whole path", hence why we raised it here instead of at oapi-codegen
